Slivered

A specific ingredient has not been confirmed as the source of the outbreak, but the US Food and Drug Administration says that the slivered onions or beef patties on Quarter Pounder sandwiches are the likely source of contamination.

For its part, McDonald’s claims that the slivered onions potentially behind the outbreak were sourced by a single supplier serving three distribution centers.

However, the slivered onions topping, which are uncooked, are processed at a facility and then sent to McDonald’s.

McDonald’s stopped using fresh slivered onions and quarter-pound beef patties in several states while an investigation is ongoing to identify the ingredients causing the illness.

The outbreak was linked to slivered onions served in Quarter Pounders, and McDonald's has since found a different onion supplier.

Almonds are available in many forms, such as whole, sliced (flaked, slivered), and as flour.
