The US Centers for Disease Control and Prevention issued a food safety alert Tuesday regarding an E. coli outbreak that it says is linked with McDonald’s Quarter Pounders.
Do you realize just how much shit has to be on your meat grinder to get people sick from a McDonald's hamburger? It's not like you can order those things rare.
FWIW it's probably not the burger meat, more likely some uncooked produce item like onions or lettuce. If it was the burger meat, it wouldn't be exclusive to the quarter pounder.
Unless something has changed, "1:4 meat" comes shipped frozen in big boxes just like "1:10 meat". I don't think I've ever seen fresh not frozen burger at a McDonald's.
They are kept unfrozen next to the grill, unlike the regular patties that remain frozen. It is not the same, even if they are shipped the same. My point being, if its not the patties then what is it? The onions/pickles are on other sandwiches as well so its unlikely to be completely unrelated to how the burgers are handled.
Not just that: it’s only one specific strain of E.Coli that does it and you also have to undercook the burger. Imagine how much cooked, otherwise safe shit is in the average burger
