Antibiotic testing in shrimp
Seafood is one of the most important exports in India with its shrimp being a staple food in many countries worldwide. However, 2017 and 2018 saw 27 shipments of shrimp refused entry into the US by the FDA. This was followed closely in January 2019, when 26 lines were refused due to the presence of two banned antibiotics, nitrofurans and chloramphenicol.
With Indian shrimp accounting for around one third of the countries seafood exports, India has expressed its concern over the rejections. It responded by calling the tests on the products ‘too stringent’.
The global shrimp industry is estimated to be worth around $30 billion and India’s market share is estimated at 13% in value terms.
Dr. Ramraj, President of the All Indian Shrimp Hatcheries Association has stated, “some of the metabolites in shrimp and crustacean shells are known to mimic antibiotics and therefore could give false results”.
The use of antibiotics in shrimp farming in India is banned. Madhusudano Rao, Principal scientist at India’s Central Institute of Fisheries Technology has said, “All shrimp hatchery operators and shrimp farmers and advised to use only these antibiotic- free inputs during shrimp farming”.
Randox Food Diagnostics offer the most comprehensive range of ELISA and Biochip tests currently on the market, specifically designed to identify and detect the smallest traces of the most prevalent antibiotics used in seafood, including nitrofurans and chloramphenicol.
Ractopamine was first developed as a treatment for asthma but was never approved according to Consumer Reports. Research later uncovered that when added to animal feed prior to slaughter, ractopamine could increase meat leanness or weight. However, ractopamine is currently banned or resisted in over 160 nations, including Russia and all European Union countries.
Ractopamine belongs to a class of drugs known as beta-agonists. These drugs mimic the effects of adrenaline, resulting in increased protein synthesis in muscle tissue during the administration period. When looking at the long-term effects of the therapeutic use of beta-agonists, side effects include a fast heart rate, widening of blood vessels, skeletal muscle tremor, nervousness, metabolic disturbances, high blood sugar and a lower than normal potassium in the blood. It is for this reason that in Europe all beta-agonists are banned for use in livestock and for improving athletic performance according to EU council directive 96/22/EC.
The United States Department of Agriculture (USDA) provide a “Never Fed Beta Agonists” program for companies that produce livestock and beef and pork products. Companies are to meet the requirements of the program if they are to supply pork or beef to customers that require verification of marketing claims that meat is derived from animals that are free of beta agonist residues.
With over 35 years’ experience within the diagnostics industry, Randox Food Diagnostics provide the highest quality products, customer service and technical support to ensure the needs of our global customer base are met. Our dedicated research and development team have therefore created our USDA approved ELISA kit for the detection of ractopamine residues. Offering excellent limits of detection, our accurate and reliable ractopamine test is applicable on urine and tissue sample types.
To ensure compliance with regulations, Randox Food Diagnostics also provide the Growth Promoter Multiple Matrix Array. Utilising our patented Biochip Array Technology, the Growth Promoter Multiple Matrix Array detects for several growth promoters in meat, including ractopamine.
