Investigation of the microbial quality of food products, cosmetics, industrial effluents and hospital wastes in Hamedan province
Abstract
Background: The Study of the microbial health of food products, cosmetic products, industrial effluents, and hospital wastes is important because they are related to human health and hygiene in society. The main purpose of this study was to investigate the microbial quality in food, cosmetics, industrial effluents, and hospital wastes in Hamadan province. Methods: In this study, microbial tests were performed for the detection and counting of bacteria, molds, and yeasts based on the culture method in 15 food products and 5 cosmetic products. Also, industrial waste microbial tests (counting total and fecal coliforms) were used by MPN method in 38 units. Microbial tests of 14 hospital units were performed by biological vial test, and class 6 microbial test. Results: Based on the obtained results, the microbial tests in 4 food products exceeded the permissible consumption limit and the rest of the products were reported as negative. Out of 5 cosmetic-sanitary products, was not allowed only one product with microbial load. Also, were reported the results of microbial tests in industrial wastes in the winter of 1401, 6 industrial units as positive, and in the spring of 1402, 2 industrial units were reported as positive. In the investigations of hospital waste, in the winter of 1401, the microbial tests of all units were negative, and in the spring of 1402, two hospital units were positive. Conclusion: Considering the importance of health in society, the requirement of microbial tests at the level of hospitals and industries should be taken into consideration.
