Now it turns out some chicken feed was tainted with melamine, the ingredient that's linked to the pet food poisonings and most recently turned up in some pork feed. The Agriculture Department and the Food and Drug Administration "said they believed the likelihood of illness to people eating contaminated chicken was low because the contamination was most likely diluted. Without evidence of harm to humans, the agencies said they were not issuing recalls of any of the processed chicken products." Doesn't look like this mess is going to end anytime soon.
