Background Psychrotrophic lactic acid bacteria (LAB) constitute a major part of microbial population in modified atmosphere packaged (MAP) meat and meat products. If allowed to grow to high levels in packaged meats, LAB may produce adverse sensory changes such as sour offodours. Leuconostoc gasicomitatum (strain DSM 15947 / CECT 5767 / JCM 12535 / LMG 18811 / TB1-10) is a psychrotrophic lactic acid Gram-positive bacterium associated with gaseous spoilage of raw tomato-marinated meat strips. This contamination is characterized by an increase in pH in conjunction with extreme bulging of the product packaging, known as "protein swell." The package bulging is caused by excessive production of gas due to amino acid decarboxylation, and the rise in pH is associated with subsequent deamination of amino acids. The consumption of marinated, raw, ready-to-cook poultry meat products has been increasing in Europe. Although these products are typically manufactured in high-quality modern processing plants, this unusual spoilage occurs occasionally during periods of quality fluctuation. Additionally to meat, L. gasicomitatum may contribute to spoilage of other chilled, nutrient-rich foods. For example, in a pickled fish and a vegetable sausage products formation of slime, gas and offodours were associated with L. gasicomitatum.
