Drug residues in fish raised on feed containing trace enrofloxacin and furazolidone

Eels and tilapia were raised in aquarium for 6-month on the feed containing traces of enrofloxacin and furazolidone to determine the veterinary drug residues in the fish tissues.The result showed that,when the amount of enrofloxacin and furazolidone in feed was lower than 200 μgkg-1for tilapias and lower than 100 μgkg-1 for eels,the drug residues in the tissues of eviscerated fish was below the MRL standard for fish.Therefore,considered the feed is suitble for feeding the fish which is safe for human consumption.
