CANADIAN BROADCASTING CORPORATION (CBC) | Does your local supermarket sell products carrying drug-resistant bacteria? A Canadian research team set out to discover whether frozen shrimp sold in supermarkets were tainted with superbugs. Researchers found that of the 51 bags of frozen shrimp they tested, 17% contained bacteria such as E. coli and staph aureus, that showed resistance to at least one antibiotic. Although the Canadian Food Inspection Agency (CFIA) does not allow for the use of any antibiotics in domestic shrimp farming, the overuse of antibiotics in Asian shrimp aquaculture has some researchers and food inspectors concerned about the potential for antibiotic-resistant bacteria landing in Canada through imported seafood. Global demand for shrimp has exploded in recent decades, worth an estimated $39 billion US and growing. Canada alone imports about $700 million in shrimp each year, with the majority of it coming from countries like India, Vietnam, China and Thailand.
