Developing countries are known to dispose waste indiscriminately into their environment of which fat is one of them. These fats release awful odor making passersby uncomfortable and also breeds microorganisms. Environmental factors such as rainfall, sunlight and wind aid the migration of these fats to other sites thereby leading to contamination. Total heterotrophic plate count of pork fat ranged from 4.0 x 105 cfu/g to 4.2 x 105 cfu/g and its total coliform plate count was from 3.8 x 105 cfu/g to 4.0 x105 cfu/g while the total heterotrophic plate count of beef fat ranged from 3.1 x 105 cfu/g to 3.5 x 105 cfu/g and its total coliform plate count was from 2.4 x 105 cfu/g to 2.8 x105 cfu/g. E.coli and Salmonella sp. were the highest occurring in both fats. Pork fat had more microbial count than beef fat. Fats can be converted to useful products and this will lead to the reduction of waste in the environment. Statistical analysis showed significant difference in mean counts of pork and beef fat samples at p<=0.05.
