Abstract
Description
A total of thirty (30) canned food samples comprising of six samples each of Sardines, Milk, Tomatoes, Meat and mixed vegetables were randomly collected from super stores, kiosks and local markets. All samples are within expiry date, none of which is bloated, leaking and/or physically damaged. Samples were analyzed by standard methods for total plate counts (aerobic and anaerobic incubations), and for spoilage, pathogenic and coliform organisms. The total aerobic plate count ranges from < 10cfu/g to 1.4x103 cfu/g. Anaerobic plate count ranges from < 10cfu/g to 1.0 x 102. Bacillus subtilis, B. coagulans, B. cereus, Clostridium perfringens, C. sporogenes, Staphylococcus aureus, Klebsiella spp and S. epidermides were isolated from some of the samples. The need for effective HACCP (Hazard Analysis Critical Control Point) is recommended to prevent under processing, pre-process and post-process contaminations, inadequate cooling, contamination from leakage through seams and pre-process spoilage
