Abstract
Summary: The microbiological contamination on porcine liver is predominantly on the surface. Storage at 5°C in air resulted in a proteolytic type of spoilage brought about mainly by Gram negative bacteria such as Alcaligenes and Pseudomonas. Other types such as Escherichia, Microbacterium thermosphactum, and lactic streptococci were also found.When stored at 5°C in polythene bags, the level of contamination was much higher in the ‘drip’, and this appears to be related to the load on the surface of the liver. The souring type of spoilage could be attributed to the predominance in the flora of lactic streptococci and Leuconostoc.Freezing was not found to change the spoilage characteristics.
