Salmonella Infections Linked to Chicken Distributed by Ruby's Pantry Pop-up Location
Four people in two states have become ill
The Wisconsin Department of Health Services (DHS), Minnesota Department of Health (MDH), Wisconsin Department of Agriculture, Trade and Consumer Protection (DATCP), Minnesota Department Agriculture (MDA), and local health departments are investigating at least four cases of salmonellosis affecting three Wisconsin residents and one Minnesota resident. All four of the patients received frozen breaded chicken products at a Ruby's Pantry pop-up location before their illnesses. Specifically, a raw breaded chicken product, that may look fully cooked, was distributed to Ruby's Pantry patrons without cooking instructions or labels stating that the product was raw.
Anyone who received any unlabeled chicken products from any Ruby's Pantry location(link is external) is advised to either discard any remaining product or cook it to an internal temperature of 165ºF. These products may be raw even if they appear cooked. Ruby's Pantry is cooperating with investigators and has voluntarily agreed to not distribute any unlabeled chicken products.
Raw chicken products can be contaminated with Salmonella or other pathogens. When handling raw chicken products, it is important to take steps to protect you and your family.
The following tips are recommended for the safe handling of raw poultry.
- Wash hands and surfaces often when handling raw poultry.
- Separate raw meats and poultry from other foods in the refrigerator.
- Refrigerate or freeze raw poultry promptly after purchasing.
- Cook all raw poultry to an internal temperature of 165ºF.
- Always follow manufacturer's instructions provided on product packaging.
- Place cooked poultry on a clean plate or platter before serving.
- Report suspected food poisoning to your local health department.
The Centers for Disease Control and Prevention has information on safe handling of raw breaded chicken products(link is external)on its food safety webpage.
Salmonellosis is caused by Salmonella bacteria that are spread by eating or drinking contaminated food or water, or by direct or indirect contact with fecal matter from infected people or animals. Symptoms include diarrhea, abdominal pains, fever, and vomiting that lasts for several days. Bloodstream infections can occur, but are rare, and can be quite serious in the very young and older people. Most people recover from salmonellosis on their own, but may require extra fluids to prevent dehydration.
If you have consumed chicken from a Ruby's Pantry and are experiencing symptoms of salmonellosis, contact your health care provider. Ill consumers in Wisconsin should also contact their local health department and ill Minnesotans should contact the Minnesota Department of Health.

ISO 45001: A New Standard in Global Occupational Health and Safety
In a global economy where your suppliers can be across town or half way around the world it can be difficult to determine if those businesses are adhering to the same health and safety standards that you are. Think of the Rana Plaza tragedy in Bangladesh in 2013 when 1,129 people were killed when the 8-story factory where they were working collapsed due to structural issues that had gone ignored. Though the global companies that bought the clothing made in this factory may have had their own safety standards, processes and programs, they had little control over the conditions and health and safety practices of the factory thousands of kilometers away.
To combat the problem, the International Organization for Standardization (ISO) has developed and released the new standard, ISO 45001:2018, Occupational health and safety management systems – Requirements with guidance for use, which provides a set of processes for improving workplace practices globally. It is intended to help organizations of all sizes and industries improve employee safety, reduce workplace risks, and create better, safer working conditions all over the world.
ISO is a United Nations recognized non-governmental organization that works in 162 countries. This standard was developed by a committee of occupational health and safety experts and takes into account other international standards such as the internationally applied OHSAS 18001 standard for occupational health and safety management systems, the International Labour Organization ILO-OSH Guidelines and the ILO's international labour standards and conventions. The ISO 45001 will replace OHSAS 18001, the world's former reference for health and safety.
Who it's for
The new standard is applicable to all organization, regardless of size, industry or nature of business. It provides government agencies, industry and other affected stakeholders with guidance for improving worker safety in countries around the world. It can help organizations provide a safe and healthy work environment for workers and visitors by continually improving their occupational health and safety functions.
Key Elements
The system takes a risk-based approach and encourages proactive prevention through the identification of activities and processes that can harm workers as well as meet legal compliance requirements. Additionally, there is an emphasis placed on the responsibilities of senior management. The system can't work without their commitment and key role in the system's implementation, maintenance, development, and promotion. This active role played by management can help to embed the management system into the culture and day-to-day operation of the business. Worker involvement is fundamental in the system's implementation through their participation in decision making, evaluating procedures and providing feedback.
Benefits
This management system provides a structured approach to protecting workers.
Potential benefits from the use of the standard include:
- Eliminating or minimizing risks
- Reduction of workplace accidents
- Reduced absenteeism and staff turnover
- Reduced cost of insurance premiums
- Creation of a health and safety culture, whereby employees are encouraged to take an active role in their own occupational health and safety
- Reinforced leadership commitment to proactively improve occupational health and safety performance
- Ability to meet legal and regulatory requirements
- Improved staff morale through commitment to safety and encouraging participation
Supply Chain
Under ISO 45001, when production is outsourced, the parent company's occupational health and safety standards must be applied. This means that companies that have traditionally outsourced difficult and dangerous activities to locations where the cost of production is lower and labour laws are lenient will no longer be able to do so. Suppliers and subcontractors must apply the same standards as the principal business so that the parent company stays in compliance. Adopting ISO 45001 requires that an organization assess its safety standards throughout their entire supply chain to prevent accidents.
Certification and compliance to ISO 45001 is not mandatory but is a way to provide valid proof that a contracting or outsourcing organization adheres to the same standards as its host or client. The steps involved in adhering to the standard can facilitate continuous improvement and this recognized certification can help support business expansion into global markets and ensure that the safety standards adhered to at the organization's home are followed by suppliers, regardless of location.

EPA extends deadline to apply for $5.5 billion in water infrastructure projects loans.
WASHINGTON –– Today, the U.S. Environmental Protection Agency (EPA) Administrator Scott Pruitt announced at a meeting with water sector associations that the deadline to submit letters of interest for Water Infrastructure Finance and Innovation Act (WIFIA) loans has been extended to July 31, 2018. Administrator Pruitt also sent a letter highlighting the deadline extension to governors of 56 states and territoriesas well as tribal leadership.
"By extending the deadline to apply for a WIFIA loan, even more entities will be able to bring critical water infrastructure improvements to their communities, including projects that keep lead and other contaminants out of drinking water," said EPA Administrator Scott Pruitt. "These projects create jobs, protect public health, and help ensure that all Americans continue to have access to clean and safe water."
EPA's announcement comes as part of Infrastructure Week and highlights the importance of working together with the water sector on a variety of topics, including affordability, governance, and the Clean Water and Drinking Water State Revolving Funds (SRFs).
Also in conjunction with Infrastructure Week, the Agency released a new interactive website that showcases leading efforts by states, public water systems, and communities to replace lead service lines.
Background
Established by the Water Infrastructure Finance and Innovation Act of 2014, the WIFIA program is a federal loan and guarantee program at EPA that aims to accelerate investment in the nation's water infrastructure by providing long-term, low-cost supplemental loans for regionally and nationally significant projects. WIFIA can provide up to 49 percent of the financing for a project and a state SRF could provide additional financing for the remaining eligible project costs. The WIFIA program received $63 million in funding in the Consolidated Appropriations Act, 2018, which was signed into law by President Donald Trump on March 23, 2018.
On April 4, 2018, EPA announced the availability of additional WIFIA funding that could provide as much as $5.5 billion in loans, leveraging over $11 billion in water infrastructure projects. This year's WIFIA Notice of Funding Availability highlights the importance of protecting public health, including reducing exposure to lead and other contaminants in drinking water systems and updating the nation's aging infrastructure.

Fire Surge: Why Are We Witnessing A 93% Increase In Waste & Recycling Facility Fires In First 4 Months of 2018
The Scope of the Problem:
In the past 12 months, we have seen 347 unique reported waste and recycling facility fire incidents in the US & Canada. When you factor in my extremely conservative assumptions that we are under-reporting waste and recycling facility fires by about 5:1, (Source:https://www.linkedin.com/post/edit/how-many-recycling-fires-have-occurred-us-canada-within-ryan-fogelman) we are looking at a reasonable number of fire incidents in the US and Canada at 1700+.
In the same time period (May 2016-Apr 2017) we encountered 277 waste and recycling facility fire incidents in the US and Canada. Using the Environmental Research & Educations Foundations data, EREF's Municipal Solid Waste In The US, published in 2016: In 2013 there were 3,913 recycling facilities and 81 WtE facilities. That would equate to 40% of Waste & Recycling Facilities have had a "Fire Incident" in the past 12 months, increasing from the 30% I had shared at WasteExpo in 2017. I realize this number might seem high to some, but when put in the context of Rumpke's reporting, of 12 fires in 2017 reported in just two of their facilities, you can see the numbers start to add up quickly.

Particulate Matter Assessment for Construction Activities
As the public is getting aware of the health implications of Dust/Particulate Matter and other pollutants, governments are expecting better pollutant management from industries. This guide provides a brief overview of a Dust pollution risk management plan for the Construction industry as well as some best practices to help mitigate the impacts.
Introduction
Construction, an important industry for global economic growth, also contributes significantly to air pollution in the form of dust. Although the exhaust from the construction vehicles and machinery adds to the NO2 levels as well, its impact is not as strong as Dust.
In scientific terms, Dust is referred to as Particulate Matter or PM. Other than being an annoyance by soiling surfaces (explanation), PM has major health and environmental implications. The WHO and the governments all around recognize PM10 and PM 2.5 (size in microns) among the most harmful pollutants. While the larger and heavier PM more commonly affect the construction site vicinity, the wind carries the lighter PM10 and 2.5 thus affecting people and vegetation miles away. Construction vehicles on the open ground further dissipate PM and carry it to farther distances.
PM is emitted at all stages of construction:
- demolition;
- earthworks;
- construction; and
- track out (The transportation of dust and dirt from the construction site onto the public road network, where it may be deposited or suspended by vehicles using the network).
The PM impact depends on factors such as the size of the construction site, duration of activity, weather conditions, the direction of the wind, proximity of people and vegetation, etc.
Harmful effects of PM
Health effects from some particles are immediate while others take years to develop. Particles greater than 10 microns cause eye, mouth, and skin irritations but PM10 and smaller are much more harmful. Europe and U.S. attribute hundreds and thousands of deaths every year to PM 2.5 and PM 10.
PM10 affects the upper respiratory system by aggravating asthma and bronchitis. PM 2.5 penetrates deeper into the respiratory tract, dissolves into the blood and compromises immunity. When dust originates from activities on a formerly contaminated site, PM10-2.5 combine with heavy metals present in soil and cause toxicity in addition. Lead and asbestos toxicity from PM is fairly common.
PM also affects the ecosystem by wilting plants as dust on leaves prevents photosynthesis.
Major construction projects over a long duration also increase the long-term PM10 concentrations in cities.
An effective assessment forms the basis of a well-planned and environment friendly construction.
But you can drastically reduce dust emission with proper measures. The mitigation controls depend on the effective assessment of dust emission prior to construction activities. An effective assessment forms the basis of a well-planned and environment friendly construction.

$54.3 Million in Brownfield Grants to Assess and Clean Up Brownfields
FARMER Program to help farmers upgrade equipment, $135 million for purchase of cleaner agricultural trucks, pump engines, tractors and more
SACRAMENTO — Funds will soon be available to expedite the purchase and use of cleaner agricultural equipment to help farmers reduce their exposure to harmful diesel exhaust, improve local air quality, and reduce greenhouse gas emissions, the California Air Resources Board has announced.
The "Funding Agricultural Replacement Measures for Emission Reductions" (FARMER) Program provides $135 million for farmers to acquire cleaner heavy duty trucks, harvesting equipment, agricultural pump engines, tractors and other equipment used in agricultural operations. The funds, available this summer, will be administered through California's regional air districts.
"Emissions from agricultural equipment are a significant source of air pollution, especially in the San Joaquin Valley. Reducing that pollution is necessary to protect public health and meet air quality standards," CARB Executive Officer Richard Corey said. "Although tough new engine standards are in effect now and will eventually lower emissions, most agricultural equipment lasts for decades. We cannot wait for the older dirtier equipment to phase out naturally, so we are taking action to improve air quality sooner by helping farmers to buy cleaner farm equipment now. This will help improve air quality throughout the state, but particularly in the San Joaquin Valley which suffers from unacceptably high levels of fine particle pollution."
FARMER funding allocations come from proceeds from the state's cap-and-trade program ($85 million), the Air Quality Improvement Fund ($15 million) and the Alternative and Renewable Fuel and Vehicle Technology Fund ($35 million). The California Legislature directed funds from these three sources to reduce emissions from the agricultural sector through grants, rebates and other financial incentives.
Because the San Joaquin Valley has the vast majority of California's agricultural operations and experiences the greatest negative health impacts from agricultural emissions, 80 percent of the funding — $108 million — will be distributed by the San Joaquin Valley Air Pollution Control District to farmers in the region.
Legislators placed special emphasis on purchasing vehicles and equipment that use advanced technologies such as clean diesel or electricity in order to accelerate improvements in air quality.

FREE Webinar: Taking Safety to the Next Level with Lockout Leadership
Time: 2:00 p.m. EDT (GMT -4, New York)
Duration: 1 Hour
Event Type: Live Webinar
Cost: Free
Description
Summary: Lockout tagout is perennially one of OSHA's top 10 violations and a leading cause of serious injuries in the workplace. What makes the difference in influencing workplace safety culture is a mentor-based leadership program. Lockout leaders perform hands-on training, day-to-day coaching, and effective inspections. This can make the difference by reinforcing the routine incorporation of energy control strategies into each task where sudden startup hazards exist.
Key Points:
- How hands-on training makes the difference when delivered by instructors embedded on the work floor
- Why having knowledgeable coaches keeping an ongoing eye on lockout practices drives continuous improvement
- How to turn auditing from a difficult chore to manage to an ongoing method of positive reinforcement
- Why lockout leadership skills can be a great start for a much broader Safety Champion program

Sarcoidosis Among U.S. Navy Enlisted Men, 1965-1993
In 1974, a 21-year-old black enlisted man had sarcoidosis diagnosed based on a chest radiograph indicating bilateral hilar adenopathy without parenchymal disease; noncaseating granulomata were present on lymph node biopsy. He had a history of shortness of breath, cough, and chest and joint pain, which he related to his work of grinding antiskid materials from aircraft carrier decks during the preceding 2 years. He received a medical discharge for sarcoidosis in 1975. In 1987, physicians at the U.S. Department of Veterans Affairs diagnosed pneumoconiosis in this patient after mineral-dust deposits were identified in a lung biopsy; the mineral-dust deposits were attributed to the same work exposures aboard the aircraft carrier. In October 1992, the patient asked the USN to request NIOSH to investigate whether his sarcoidosis diagnosis and other cases diagnosed in persons with whom he had served in the USN may have been associated with environmental exposures during their USN service. Because of the possibility of an association between risk for sarcoidosis-like illnesses and environmental exposures during service in the USN and because the underlying cause(s) of sarcoidosis is unknown, in December 1992 the USN requested that NIOSH evaluate the potential relation between sarcoidosis and the USN work environment.

Cellphone Radiation Linked to Brain and Heart Tumors studies are reproducible
In 2011 the International Agency for Research on Cancer (IARC) classified cellphones as a Group 2B "possible carcinogen,"1 and the evidence supporting the theory that electromagnetic field (EMF) radiation from cellphones can trigger abnormal cell growth and cancer2,3 just keeps growing and getting stronger.
In February, the findings of two government-funded animal studies4 were published. Curiously enough, the published interpretation of this $25 million research (conducted by the National Toxicology Program (NTP), an interagency research program currently under the auspices of the National Institute of Environmental Health Sciences) significantly downplays the actual findings of the studies.
Cellphone Radiation Linked to Brain and Heart Tumors
The NTP research includes two studies: one on mice and one on rats. Male rats were more likely to develop heart tumors, while female rats and newborns exposed to high levels of radiation during pregnancy and lactation were more likely to have low body weight. DNA damage and damage to heart tissue were also observed in both male and female rats, but not mice. Other types of tumors did occur in both types of animals, though, including brain, prostate, liver and pancreatic tumors.
According to the researchers, if these results can be confirmed, then cellphone radiation may indeed be a "weak" carcinogen. As you'll see below, that confirmation was delivered last month, in the form of published research by the Ramazzini Institute.
The animals in the NTP studies were exposed to cellphone radiation for nine hours a day for two years (basically the full life span of a rat). As noted by The New York Times,5 the heart tumors (malignant schwannomas) found in male rats are "similar to acoustic neuromas, a benign tumor in people involving the nerve that connects the ear to the brain, which some studies have linked to cellphone use."
The scientists also expressed surprise at the finding of DNA damage, as the conventional belief is that nonionizing radiofrequency radiation cannot harm DNA. "We don't feel like we understand enough about the results to be able to place a huge degree of confidence in the findings," John Bucher, Ph.D.,6 senior scientist at the NTP told reporters. Such statements fly in the face of warnings issued by NTP researchers two years ago.
NTP and Ramazzini Show Effects Are Reproducible
The NTP-funded studies found rats exposed to RF radiation began developing glial cell hyperplasias — indicative of precancerous lesions — around week 58; heart schwannomas were detected around week 70. Ramazzini's study confirms and reinforces these results, showing RF radiation increased both brain and heart tumors in exposed rats. This, despite the fact that Ramazzini used much lower power levels.
While NTP used RF levels comparable to what's emitted by 2G and 3G cellphones (near-field exposure), Ramazzini simulated exposure to cellphone towers (far-field exposure). In all, the Ramazzini Institute exposed 2,448 rats to 1.8 GHz GSM radiation at electric field strengths of 5, 25 and 50 volts per meter18 for 19 hours a day, starting at birth until the rats died either from age or illness.
To facilitate comparison, the researchers converted their measurements to watts per kilogram of body weight (W/kg), which is what the NTP used. Overall, the radiation dose administered in the Ramazzini study was up to 1,000 times lower than the NTP's — yet the results were strikingly similar. As in the NTP studies, exposed male rats developed statistically higher rates of heart schwannomas than unexposed rats.
They also found some evidence, although weaker, that RF exposure increased rates of glial tumors in the brains of female rats. As noted by Ronald Melnick, Ph.D., a former senior NIH toxicologist who led the design of the NTP study and current senior science adviser to the Environmental Health Trust:19
"All of the exposures used in the Ramazzini study were below the U.S. FCC limits… In other words, a person can legally be exposed to this level of radiation. Yet cancers occurred in these animals at these legally permitted levels. The Ramazzini findings are consistent with the NTP study demonstrating these effects are a reproducible finding. Governments need to strengthen regulations to protect the public from these harmful non-thermal exposures."
The NTP's conclusion that there's no cause for concern is also challenged by an independent review panel, which concluded its review of the two NTP studies March 28. According to this panel of experts, there's "clear evidence" linking RF radiation with heart schwannomas and "some evidence" linking it to brain gliomas. It remains to be seen whether the NTP will accept or reject the panel's conclusions in its final report.
Why Evidence of Rodent Schwannomas Could Spell Trouble for Human Health
As explained by Louis Slesin, Ph.D., editor and publisher of Microwave News, the increased incidence of schwannomas in rodents exposed to RF is no mere coincidence, and is of great concern for public health:20
"Schwann cells play a key role in the functioning of the peripheral nervous system. They make the myelin sheath, which insulates nerve fibers and helps speed the conduction of electrical impulses. There are Schwann cells just about everywhere there are peripheral nerve fibers. They are present in most organs of the body — whether mice, rats or humans. Schwann cell tumors are called schwannomas.
The NTP found schwannomas in many other organs, in addition to the heart, of rats chronically exposed to cellphone radiation. These included a variety of glands (pituitary, salivary and thymus), the trigeminal nerve and the eye … The NTP also saw schwannomas in the uterus, ovary and vagina of female rats. The brain has no Schwann cells —the brain is part of the central nervous system. There, glial cells play a similar function. In fact, Schwann cells are a type of glial cell …
Tumors of the glial cells are called gliomas. The NTP also saw an increase in glioma among the male rats exposed to GSM and CDMA radiation. Higher rates of glioma have been reported in a number of epidemiological studies of cellphone users. The other tumor linked to cellphone radiation in human studies is acoustic neuroma, a tumor of the auditory nerve … formally called a vestibular schwannoma.
While schwannomas and gliomas are commonly noncancerous tumors, they can develop into malignant schwannomas or glioblastomas … The implication is that instead of searching for consistency in RF's ability to cause cancer in specific organs, the emphasis should now be on specific cell types — beginning with Schwann cells in the periphery and glial cells in the brain."

EPA Announces New Funding for Water Infrastructure Projects
"Thanks to the President's leadership, this WIFIA funding will spark new investments to repair our nation's crumbling water infrastructure," said EPA Administrator Scott Pruitt. "EPA will play a key role in the President's infrastructure efforts by incentivizing states, municipalities, and public-private partnerships to protect public health, fix local infrastructure problems, create jobs, and provide clean water to communities."
The WIFIA program received $63 million in funding in the Consolidated Appropriations Act, 2018, which was signed into law by President Donald Trump on March 23, 2018. This more than doubles the program's funding from 2017. Leveraging private capital and other funding sources, these projects could support $11 billion in water infrastructure investment and create more than 170,000 jobs. This year's Notice of Funding Availability (NOFA) highlights the importance of protecting public health including reducing exposure to lead and other contaminants in drinking water systems and updating the nation's aging infrastructure.
"An investment in water infrastructure is an investment in our communities," said Dr. Andrew Sawyers, director of the Office of Wastewater Management. "The WIFIA program helps improve water quality and protect public health while supporting the local economy."
The WIFIA program will play an important part in making vital improvements to the nation's water infrastructure and implementing the President's Infrastructure Plan, which calls for increasing the program's funding authorization and expanding project eligibility.
Background
Established by the Water Infrastructure Finance and Innovation Act of 2014, the WIFIA program is a federal loan and guarantee program at EPA that aims to accelerate investment in the nation's water infrastructure by providing long-term, low-cost supplemental loans for regionally and nationally significant projects.
WIFIA credit assistance can be used for a wide range of projects, including:
- Drinking water treatment and distribution projects;
- Wastewater conveyance and treatment projects;
- Enhanced energy efficiency projects at drinking water and wastewater facilities;
- Desalination, aquifer recharge, alternative water supply, and water recycling project; and
- Drought prevention, reduction, or mitigation projects.
EPA will evaluate proposed projects described in the LOIs using WIFIA's statutory and regulatory criteria as described in the NOFA. Through this competitive process, EPA will select projects that it intends to fund and invite them to continue to the application process.
In 2017, for WIFIA's inaugural round, EPA invited 12 projects in 9 states to apply for more than $2 billion in WIFIA loans.

Improved Tool Decreases Dangerous Airborne Silica Dust

During sand transport, a visible cloud of dust containing crystalline silica floats past this top sand-mover operator station. Photo courtesy of Barbara Alexander, NIOSH.
An improved, NIOSH-developed tool, or engineering control, can help reduce the amount of dangerous, airborne crystalline silica dust generated during sand moving for oil and gas extraction, according to research published in the Journal of Occupational and Environmental Hygiene.
During hydraulic fracturing for oil and gas extraction, workers use equipment that pumps millions of pounds of water and sand into rock formations deep underground. The purpose of this pressurized mixture is to create and maintain cracks in the rock to extract the oil and gas trapped within. The problem is that the sand usually contains crystalline silica dust, which, when inhaled, can cause severe illness, including lung cancer and the deadly lung disease silicosis. During certain tasks, such as moving and mixing sand at hydraulic-fracturing sites, airborne crystalline silica dust poses a serious risk to workers' health.
Engineering controls are a critical part of preventing worker exposure to airborne crystalline silica dust. In fact, respirable crystalline silica standard 29 CFR 1910.1053 from the Occupational Safety and Health Administration will require hydraulic-fracturing companies to adopt engineering controls for crystalline silica dust by June 23, 2021.
NIOSH investigators who study and develop these engineering controls showed in previous research that a NIOSH-developed control effectively reduced levels of airborne crystalline silica dust released from inspection hatches on top of sand movers. Known as the NIOSH mini baghouse, it comprises four large bags made of filter material and a baseplate that clamps to the openings on top of sand movers. It is unique in that it has no moving parts, requires no power source, and can retrofit to existing sand movers.
In a study of the third generation of the mini baghouse, investigators tested it at an Arkansas sand mine during May 19–21, 2015. They collected 168 air samples at 12 locations on and near a sand mover, both with the mini baghouse installed and without it, and then measured the levels of respirable crystalline silica dust in the air samples. The measurements showed that air samples taken with the mini baghouse installed contained 98%–99% less respirable crystalline silica dust than those taken without the mini baghouse. In addition, other tests showed that the crystalline silica dust probably contained freshly fractured quartz, which is an especially dangerous type of crystalline silica dust.
Compared to earlier versions, this third-generation mini baghouse performed significantly better due to improvements, such as a larger surface area of a "slipperier" filter fabric. Now, the investigators are studying additional design improvements, including a cover to offer protection from the weather. They also are planning future trials looking at long-term use of the mini baghouse.
