What is a clever, witty and insulting way to counter this statement?

So my friend said something stupid and I want a funny reply (it was his facebook status):

lol so the news is saying that beef is getting recalled because it has E Coli on it... R THEY FUCKING STUPID? ALL, literally ALL beef has E Coli on it, that's why you COOK IT you stupid mother fuckers. another prime example of corporations getting blamed for peoples IDIOCY. if you don't cook beef, and you get sick, it's yo own damn fault.

Too much e coli in the meat can't be cooked away. In other words, this is why the FDA doesn't hire dumb f#cks like you.
