FDA only tolerates contamination for human food but not animal food products

Why are conditions in Florida food processing facilities allowed contamination and protected from recalls but not animal food manufacturers and distributors ?

Filthy conditions, failure to correct violations prompted action at Kentucky facility
At the request of the U.S. Food and Drug Administration, U.S. marshals today seized livestock and horse feeds stored under filthy conditions at the Bi-County Farm Bureau Cooperative Association, Inc., in Florence, Ky.

“The FDA will not tolerate a company’s failure to adequately control and prevent filth in its facility,” said Michael Chappell, the FDA’s acting associate commissioner for regulatory affairs. “The FDA is prepared to use whatever legal means are necessary and appropriate to keep potentially contaminated products out of the marketplace.”

During a recent inspection of the Bi-County feed mill, FDA investigators discovered live and dead mice and evidence of bird activity throughout the facility. FDA laboratory analysis of samples collected during the inspection confirmed the presence of rodent urine, rodent feces, rodent hairs, and rodent-gnawed holes in bags, in and around food products.
