Two Samples

Objective: Owing to the habit of consuming ready food among the citizens of Malaysia a study was conducted to evaluate 20 samples of canned soya milk for the presence of possible microbial content. The samples were collected randomly from shopping malls, restaurants and kiosk in Ipoh Malaysia. Methods: All samples collected across Ipoh, were subjected to test for presence bacteria in nutrient agar, blood agar and macConkey media. The possible microbial load was swapped from surface and soya milk content with a sterile cotton and streaked on nutrient agar, blood agar and macConkey culture media. The streaked petri plates were incubated for 48 hours at 37oC. Results: The study revealed negative microbial growth in all except two samples from the surface and soya milk content collected from a restaurant in nutrient agar and blood agar medium. The presence of microbes was conformed as gram positive staphylococcus sp. through gram staining. The positive growth may be imputed to poor storage condition at the restaurant. Conclusion: It can be computed from the study that the majority of the samples were free from bacterial growth, suggesting strong in house quality control mechanism at the processing unit and exquisite storage conditions in malls and kiosk suggesting that soya milk available in malls and kiosk are fit for human consumption.
