GRAND ISLAND, Neb. — The discovery of E. coli in beef produced Wednesday at the JBS meatpacking plant in Grand Island caused the plant to cease full production until Friday.
“This doesn't happen very often,” JBS spokesman Chandler Keys said. “But when it does, we have processes in place to rework and clean.”
Keys said JBS tests “every bit of trim” meat in the plant. The trim meat is the “indicator meat” for all meat processed. Trim meat tests on Wednesday found that some of the cattle brought into the plant had E. coli and that E. coli had gotten onto produced meat cuts.
Although the plant has a tracking system to indicate exactly which cuts of meat and carcasses tested positive for E. coli, the policy is to clean and retreat all the meat processed within a half-day of the positive test, Keys said.
