slivered

In October, McDonald’s faced a major setback after it found itself at the center of an E. coli outbreak linked to slivered onions in its Quarter Pounders.

Last fall, the fast-food giant landed in hot water after a deadly E. coli outbreak was traced back to fresh, slivered onions served on its Quarter Pounder hamburgers.

The burgers were temporarily removed from some locations before they made a comeback, albeit without slivered onions.

Fresh, slivered onions at McDonald’s were the likely source of the outbreak, the CDC said, in line with previous reports.

The recent releases come after McDonald’s said it plans to invest $100 million in hopes of bringing back customers following an E. coli outbreak linked to slivered onions on the Quarter Pounder hamburgers.
