Ten percent of 30 imported shrimp samples from various grocery stores in the US were found to contain traces of illegal antibiotics, according to a report by ABC World News. The analytical tests were conducted at Texas Tech University, and technicians there found the following US-banned antibiotics: enrofloxacin, chloramphenicol, and nitrofuranzone. Antibiotics are used in aquaculture to aid in producing a healthy population, but use of antibiotics is becoming less of norm, according to a Food Safety News article.
The FDA inspects about two percent of all imported shrimp. According to the FDA interview in the ABC news report, an occasional shrimp containing banned antibiotics is not a significant health risk. The FDA also noted its sampling methods are adequate, and that it also pressures the foreign shrimp industry to police itself in regards to ensuring shrimp exported to the US are safe.
