Veterinary drugs which are easy to cause excessive veterinary drug residues in animal-derived foods are mainly antibiotics, sulfonamides, furans, antiparasitic and hormone drugs.

1. Antibiotics: 

A large number of frequent use of antibiotics can make drug-resistant pathogenic bacteria in animal organisms easily infect humans; moreover, antibiotic drug residues can make bacteria in human body produce drug resistance, disturb human micro-ecology and produce various toxic and side effects. At present, the main antibiotics that easily cause excessive residues in livestock products are chloramphenicol, tetracycline, oxytetracycline and aureomycin.

2. Sulfonamides: 

Sulfonamides are mainly residues in animal-derived foods through infusion, oral administration, traumatic external use or as feed additives. The residues of sulfonamides in animal derived foods exceed the standard. They are very serious in pigs, poultry and cattle.

3. Hormones and beta-stimulants: 

Hormones and beta-stimulants commonly used in aquaculture include sex hormones, corticosteroids and clenbuterol hydrochloride. Many studies have shown that residues of hormonal drugs such as clenbuterol and diethylstilbestrol in animal-derived foods can be extremely harmful to human health. Among them, clenbuterol hydrochloride (clenbuterol hydrochloride) is easy to cause residues in animal-derived food. When the intake of clenbuterol hydrochloride is more than 20 UG in healthy people, it will be effective. When the intake of clenbuterol hydrochloride is 5-10 times, it will lead to poisoning.

4. Other veterinary drugs: 

furazolidone and nifurenone are often used in the feed of pigs or chickens to prevent diseases. They should be zero residues in animal derived foods, that is, they must not be detected. They are prohibited veterinary drugs in Chinese food animals. Benzimidazoles can accumulate in various tissues and organs of the body, and have high residues in meat, eggs and milk during the administration period.
