E. coli in steak: What you need to know
Is it always safe to eat a steak served rare? Seems like a simple question.
But a Dec. 24 National Steak and Poultry recall of almost 250,000 pounds of blade-tenderized beef forced consumers and health officials to reevaluate the question—especially after government agencies associated the recalled beef with 21 cases of E. coli in 16 states.
Typically, ground beef comes to mind when considering meat that could be tainted with E. coli. But this outbreak involved blade-tenderized, or what health officials call “non-intact” beef, which included steaks, beef medallions and sirloin tips. “Blade-tenderized” or “non-intact” refers to meat that has been punctured with needles or blades to break down the tissue and make a tougher cut of muscle more tender. Any pathogen (like E. coli) on the surface of the beef is normally killed in the cooking process if the beef is intact. But the mechanical tenderization process drives pathogens inside the beef. If it isn’t cooked until the internal temperature reaches at least 140 degrees, the beef could still contain the pathogen.
Government officials and industry groups offer mixed advice on what consumers should do. The National Advisory Committee on Microbiological Criteria for Foods determined in 2002 that non-intact beef can indeed harbor infective amounts of E. coli, but that following the 140-degree rule will put you in the clear. A 2002 risk assessment by the USDA’s Food Safety and Inspection Service (FSIS) concluded there is almost no difference in risk of illness from intact versus non-intact steaks.
And yet there have been several E. coli outbreaks since then involving mechanically tenderized meat. This has put the spotlight on the issue of labeling. If non-intact steak must be cooked a certain way to guarantee its safety, then shouldn’t consumers have the right to know whether their steak is intact so they can cook it accordingly? That was the recommendation issued in a 2005 study by the Minnesota Department of Health following a 2003 outbreak of E. coli associated with blade-tenderized frozen steaks sold by door-to-door salesmen. In light of the National Steak and Poultry outbreak, U.S. Rep. Rosa DeLauro called for labeling of non-intact steaks, stating “USDA has been aware of the E. coli risks associated with mechanically tenderized steaks as early as 1999, but has refused to act…consumers should be made fully aware of the products they are receiving so they can assure that they are cooked at the appropriate temperature.”
Furthermore, does this mean every time we eat at a restaurant, we should order our steak cooked to an internal temperature of 140 degrees? The National Restaurant Association in 2000 decided that restaurant patrons asking for rare- or medium-cooked steak should be informed that non-intact steaks should be cooked to at least 145 degrees to ensure safety. But when is the last time your server told you that?
