The Environment Agency has reportedly held a series of meetings with the pharmaceutical industry to determine whether there are any risks from Prozac to the environment or to human health.
A spokesman for Britain's Drinking Water Inspectorate tried to calm fears, reporting that the traces found were unlikely to be a danger to health. Several sources report this spokesman as saying that "It is extremely unlikely that there is a risk, as such drugs are excreted in very low concentrations. Advanced treatment processes installed for pesticide removal are effective in removing drug residues." Britain's Liberal Democrats have already criticized the Inspectorate's statement. Environment spokesman Norman Baker is quotes as saying that it looked "like a case of hidden mass medication upon the unsuspecting public".
