Studies on antibiotic residues in imported and locally frozen chicken meat

Poultry production plays an important role as good and cheap source of animal proteins in Egypt. The extensive and misuse of antibiotics for control of disease and growth promotion resultedin a problem of drug residues.Prevention of residues in meat and poultry is a top of priorityof the public health authorities. Recently, residues in meat andpoultry represent a major problem facing the hygienists. Now thepublic health authorities in different countries had established’regulations of the Veterinary use of the drugs in food of animals andpoultry origin.So, the present study was performed to determine the presence of antibiotic residues in locally and imported frozenchicken meat and also the detection of effect of cooking procedures(boiling, frying and roasting) on positive samples that containantibiotic residues.so, the following experiment were performed.I)Qualitative detection of antibiotic residues in randommarket froze chicken meat samples using the microbiological assay technique:A total of 120 fozen chicken samples were collected from chicken shops and supermarkets at Dakhahlia Governorate, Egypt.All samples were examined for presence of antibiotic residues usingmicrobiological inhibition test. The freshly prepared Bacillus’subtilis plates was used and incubated at 30°C for 24 hours. Theresults revealed that the incidence of antibiotic residues as follow noresidues was detected in imported frozen chicken meat but theresidues concentrated in local frozen chicken meat as follow
