That's the conclusion of a recent consumer report that studied the safety of frozen shrimp sold in the United States. The results were really quite horrifying. The investigators purchased 342 packages of frozen shrimp. Some were raw and some were cooked; sold ready to eat. They were all bought from major supermarket chains in the US. The shrimp were tested for disease causing pathogens like bacteria and viruses, as well as antibiotics. Antibiotics are not permitted to be used in shrimp aquaculture in the USA because they contribute to the spread of antibiotic resistant bacteria. Worryingly, antibiotics were found in 11 of the samples, which had all been imported from Asia. Approximately 94 percent of shrimp on the American market is imported, mostly from India, Thailand and Indonesia; countries that do not adhere to FDA safety guidelines. Shrimp has become so popular in the US that it is now consumed more than tuna. 60 percent of the shrimp tested in this study contained bacteria that is capable of making people sick. Even 16 percent of the cooked, ready to eat shrimp was contaminated with harmful bacteria. One type of bacteria found was vibrio, which is potentially lethal and sometimes found in raw oysters. This type of bacteria is becoming increasingly prevalent in seafood due to the rising of the temperature of the world's oceans. Very off-putting if you're a fan of shrimp, isn't it? Wild seafood is almost always preferable to farmed seafood and should be your number one choice if available and affordable.   Reference
