The U.S. Department of Agriculture (USDA) and the U.S. Food and Drug Administration (FDA) have learned that by-products from pet food manufactured with contaminated wheat gluten imported from China have been used in chicken feed on some farms in the state of Indiana.
This information came to light as part of the continuing investigation into imported rice protein concentrate and wheat gluten that have been found to contain melamine and melamine-related compounds.
At this time, the investigation indicates that approximately 30 broiler poultry farms and eight breeder poultry farms in Indiana received contaminated feed in early February and fed it to poultry within days of receiving it. All of the broilers believed to have been fed contaminated product have since been processed. The breeders that were fed the contaminated product are under voluntary hold by the flock owners.
As with exposure from hogs fed contaminated pet food and for similar reasons related to the dilution of the contamination, FDA and USDA believe the likelihood of illness after eating chicken fed the contaminated product is very low.
Because there is no evidence of harm to humans associated with consumption of chicken fed the contaminated product, no recall of poultry products processed from these animals is being issued. Testing and the joint investigation continue. If any evidence surfaces to indicate there is harm to humans, the appropriate action will be taken.
Because the poultry being held have been fed adulterated products, USDA cannot knowingly approve products derived from these poultry for human consumption.
USDA is offering to compensate producers who euthanize this poultry. USDA is also offering the expertise and assistance of Animal and Plant Health Inspection Service (APHIS) personnel in carrying out depopulation activities, to ensure adherence to federal and state laws.
FDA and USDA anticipate that as the investigation continues additional farms will likely be identified that received contaminated feed. As indicated in previous updates, FDA and USDA have also traced contaminated feed to swine farms in several states.
The same procedures are being followed in relation to both swine and poultry; animals are being quarantined by state order or voluntarily held by the owners and USDA is offering compensation for depopulation and disposal of both swine and poultry that have been fed contaminated products.
USDA and FDA continue to conduct a full, comprehensive examination to protect the nation's food supply and will provide updates as new information is confirmed.
