That's a recall not an outbreak. Testing caught it before people actually got sick. E. Coli is prevalent in a lot of the animals guts already. It's all about how it was processed at the plants. It's not in the meat it's in the gut and careless processing causes contamination. Ground beef is a problem because the E. Coli is on the surface of the meat cuts. Grind it up and the contamination is spread all over. Steaks on the other hand the contamination can be on the surface so that's why you can do rare usually without and issue.
