"Raw, wild-caught shrimp from U.S., Argentina had lowest bacteria levels of all samples tested

A new Consumer Reports (CR) study released Friday found that 60 percent of 342 samples of frozen shrimp it tested contained Salmonella, Vibrio, Listeria, or E. coli, and 2 percent tested positive for the superbug MRSA (Methicillin-resistant Staphylococcus aureus).
For its new report, “How Safe is Your Shrimp?,” CR researchers bought 284 raw and 58 cooked shrimp samples for testing last March in 27 cities across the country from retailers such as Walmart, Kroger, Albertsons, Costco, Fry’s Marketplace, Hy-Vee and Sprouts Farmers Market. CR didn’t test fresh, never-frozen shrimp since U.S. consumers don’t buy much of that."
