Washington (CNN) -- The U.S. government is not fully guarding against the contamination of meat by traces of antibiotics, pesticides or heavy metals, a new report warns.
The U.S. Department of Agriculture's inspector general said federal agencies have failed to set limits on many potentially harmful chemical residues, which "has resulted in meat with these substances being distributed in commerce."
When it comes to pesticide traces, only one type is tested for, according to the report. There are also no set limits for some heavy metals, like copper.
In 2008, Mexican authorities turned away an American shipment of beef, because it did not meet Mexico's limits when tested for copper traces. But the very same rejected meat could be sold in the United States, since no limit has been set, the analysis says.
That example shows "the government has fallen down on the job here," said Tony Corbo of the consumer advocacy group Food and Water Watch.
"Some of the residues that the inspector general cited could be carcinogenic, as they accumulate over a period of time in the body," he said.
The study focused on contamination by chemical residues, rather than bacteria. While bacteria like E. coli and Salmonella can cause an illness that is acute but brief, chemical residues are more like to build up over time, and no amount of cooking will destroy them.
