Farmed Shrimp Still Safe, Antibiotic Use Declining

23 May 2012, at 1:00am

GLOBAL - Despite the impression left by a recent ABC News story on farmed shrimp, the use of antibiotics is neither a common nor accepted practice in shrimp farming. In fact, great progress has been made to eliminate antibiotics, and shrimp can now be obtained from certified sources that provide the food safety assurance that consumers demand.

Shrimp imports to the United States are subject to multiple controls. The US Food and Drug Administration routinely tests imported seafood. Further, exporting countries test and screen shrimp for banned antibiotics and chemicals before it leaves their borders, and countries like China and Thailand also monitor their shrimp farms directly.

For added assurance, seafood buyers typically require their suppliers to test for illegal substances - a requirement that is now mandatory for certification programs such as Best Aquaculture Practices (BAP), which the Global Aquaculture Alliance (GAA) developed specifically to address concerns such as antibiotics.

BAP-certified farms produce 192,350 tons (174,500 metric tons) of shrimp annually. Most of this volume is sent to the United States, where it represents over a quarter of the shrimp imported to the US

"The shrimp-farming industry recognises the use of antibiotics in food production should be avoided due to concerns about food safety and the development of antibiotic-resistant bacteria," GAA President George Chamberlain said. "The technology for disease management in shrimp farming has made transformative advances."

Pathogens are increasingly managed through the use of specific pathogen-free broodstock and breeding for genetic resistance to disease. At farms, proper pond preparation, disinfection of incoming water and the application of beneficial bacteria to displace pathogens help limit diseases.

The use of banned substances has been reduced thanks to stiffer regulation and enforcement, and pressure from responsible buyers who refuse to buy suspect shrimp. Education also plays a role.

"GAA has an active educational program to assist farmers, regulators and policy makers in understanding the importance of health management through prevention," Mr Chamberlain said. "We hope further training will help move all aquaculturists further away from the use of unapproved chemicals."

Aquaculture is an increasingly important source of safe, nutritious, and sustainable seafood for people worldwide. Globally, aquaculture production must double by 2030 to keep pace with demand. These increases in demand for aquaculture products, food security considerations, and job creation have generated an increased need for skilled workers.
