A total of four samples of evaporated milk (Peak, Nunu, Luna and 3 Crown) were analyzed for their microbial load when punctured and left open for 48h without proper storage. The percentage occurrence of Staphylococcus aureus and Escherichia coli obtained from Peak and Luna milk was 20% each while that of Aspergillus species was 50%. The percentage occurrence of Pseudomonas fragi, Microccus leteus, Shigella species, Klebsiella pneumoniae, Serratia marscens and Proteus mirabilis were 10% each while Rhodotorula species Penicillum chrysogenum and Rhizopus spe- cies had a frequency occurrence of 20%, 20% and 10% respectively. The study shows that it is a health risk to consume evaporated milk exposed to air for or long period after opening.
