Antibiotics are drugs that inhibit bacterial growth or treat bacterial infections for both humans and animals. In recent years, farmers have extensively added antibiotics to feeds to prevent the occurrence of animal diseases, to promote animal growth and to increase economic efficiency. Improper use of antibiotics or failure to comply the withdrawal period makes it easier to accumulate in the animal products. The transmission of the food chain poses a serious threat to the health of the consumer.
The US FDA and the European Commission have restrictions on the maximum level of antibiotic residues in food.
The rapid test is based on the principle of immunochromatography and is convenient with fast detection speed, high specificity and accuracy. Antibiotic hapten-colloidal gold complex competing with the antibiotics in the sample displays one line (Control line) if antibiotic is present in the sample, which indicates a positive reaction. Two lines (Control and test line) indicates a negative result which means no antibiotic components detected in the sample.
