Prevalence Of Antibiotic Resistant Staphylococcus Aureus In Milk, Milk By- Products And Food Handler At Retail - 2012
The present study was conducted to check the prevalence of antibiotic resistant Staphylococcus aureus in milk, milk products and food handlers at various dairy retail shops in Lahore. A total of 100 samples, 30 samples of raw milk, 30 samples of pasteurized milk, 20 samples of yogurt, 10 samples of butter and 10 hand swabs samples of dairy handlers were analyzed. Staphylococcus aureus was detected in 54% (54 out of 100) samples.
Overall high prevalence was recorded in raw milk, followed by hand swabbing samples of dairy handler, butter, pasteurized milk and yogurt. The results indicated unhygienic practices during milking and handling of milk at different critical control points such as transportation, storage, and post-pasteurization contamination. Overall high prevalence of ampicillin and amoxicillin resistant Staphylococcus aureus were recorded in all the samples of milk and milk products and the hand swabbing of dairy handlers, followed by resistant against chloramphenicol, trimethoprim, streptomycin and vancomycin respectively. All the isolates were resistant to ampicillin followed by resistance against amoxicillin, chloramphenicol, trimethoprim, streptomycin and vancomycin which were 92.6%, 37%, 33.3%, 24.1% and 22.2% respectively.
The antibiotic resistant Staphylococcus aureus in milk and milk products indicated the widespread use of these antibiotics in treating different types of infections associated in either livestock or humans which results in selection pressure of these antimicrobials and results in the emergence of these antibiotic resistant bacteria in different environmental conditions. The risk associated with human health as a result of ingestion of these antibiotic resistant bacteria can be prevented by adopting hygienic measures during milking, transport, storage and hygienic handling by the handlers so the human health can be assured.
