Behavior of Salmonella typhimurium in pork minced meat and pork skin at diferent storage temperatures

Abstract

Salmonella is a common contaminant of pork and can present a health hazard to consumers. Therefore, for an effective control, the entire supply chain must be involved. The aim of this paper is to examine the survival of Salmonella Typhimurium in pork minced meat and skin at different temperatures and time. In minced meat, stored at +4 ± 0.5°C during 72 h, the number of Salmonella Typhimurium of all three examined strains A, B, and C decreased (p<0.01). In minced meat, stored at +10 ± 1°C after 72 h, the number of Salmonella strain A was significantly higher (p<0.01), while for strains B and C, no statistically significant difference was determined (p>0.05). On the skin, stored at +4 ± 0.5°C during 72 h, the number of Salmonella of strains A and B decreased (p<0.01), while for strain C, no statistically significant difference was determined (p>0.05). On the skin, stored at +10 ± 1°C during 72 h, the number of Salmonella of strains A and C decreased (p<0.01), while for strain B, no statistically significant difference was determined (p>0.05).
