They killed someone in the UK. McDonald’s literally just killed someone with bad quarter pounders.

To add context, the CDC announced the cause to be the yellow onions [1] in the quarter pounders; McDonalds stopped serving onions in their quarter pounders and stopped sourcing onions from that supplier facility “indefinitely” (Taylor Farms in Colorado Springs) [2].
