Cover Story: Clostridium estertheticum is a psychrotolerant spore-forming anaerobe, and the main cause of blown pack spoilage (BPS). BPS occurs in vacuum-packed meat without temperature abuse. BPS occurs worldwide, accounting for significant losses in the meat industry. Several factors, including animal physiology, determine the ultimate pH and glucose levels in meat, and post-slaughter exposure of meat to environmental microbial contaminants may promote BPS. The early detection and prevention of BPS has been hampered by a lack of studies, due to the poor growth of Cl. estertheticum under normal laboratory conditions. However, the few strains of Cl. estertheticum that are available have been characterized phenotypically and provided vital data that can be used to control BPS. These include growth conditions in meat juice, inactivation by peroxyacetic acid, and inhibition by lactic acid bacteria. View this paper.
