This is the first time the exact cause of the outbreak, which occurred in April and Mayhas been disclosed to the public.
The outbreak was first publicly reported by federal health authorities on May 19,with an announcement that ground beef produced by Detroit-based Wolverine Packing Company had sickened at least 12 people in 4 states.

Other patients ordered burgers from a brew pub in St. Each of the restaurants received Wolverine beef, although documents do not specify how those burgers were cooked. Chapman is currently leading a nationwide study to assess how well restaurants inform their customers about the risks of undercooked burgers.

To start, restaurants need strict supplier control, Costa said. They should only buy beef from suppliers who perform microbial testing and provide certificates of analysis. When asked if he knew of any restaurants performing both those steps, Costa said he did not.
Another option, Theno said, is to use cold-pasteurized beef. Through processes such as irradiation and electron-beam pasteurization, beef suppliers and restaurants can eliminate any bacteria and parasites from raw beef.
While some restaurants and grocery stores now offer cold-pasteurized beef, the practice is still far from mainstream. But what about the segment of the population who are fully aware of the risk and still want to enjoy a medium-rare, irradiation-free burger?
If they get sick despite knowing the risk, are they responsible for their illness, or is the restaurant still on the line?
Legally speaking, the restaurant is ultimately responsible.
Ultimately, Costa said, consumers are the ones who risk illness and injury from a contaminated burger, and everyone should do the best they can to educate themselves on the risks and make informed choices.
