Federal regulators said a Cargill livestock feed plant involved in a sizable aflatoxin-related recall last year violated food-safety regulations.
The U.S. Food and Drug Administration (FDA) this week posted a "warning letter" to Cargill, saying a feed plant in North Carolina didn't adhere to requirements for good manufacturing practices, hazard analysis and "risk-based preventive controls."
Cargill said in a statement that it "aggressively implemented" corrective measures after the recall and an ensuing FDA inspection.
"We have since provided a written response to the FDA updating them with the systematic improvements that have been put in place."
The FDA inspected the plant in June following voluntary recalls in May by Cargill of 24 million pounds of horse, cattle, poultry, goat and sheep feed.
The recalls stemmed from elevated levels of aflatoxin, which is found on moldy crops. If eaten, aflatoxin can be deadly to animals.
The North Carolina Department of Agriculture discovered the aflatoxin contamination when testing a specific Cargill product.
Minnetonka-based Cargill traced the problem to moldy corn from a supplier to its plant in Cleveland, N.C.
