Aim: To investigate Listeria monocytogenes contamination and behaviour in naturally contaminated French cold-smoked salmon (CSS).
Method And Results: Between 2001 and 2004, L. monocytogenes was detected in 104 of 1010 CSS packs, produced by nine French plants, with different prevalence (from 0% to 41%). The initial contamination, measured with a sensitive filtration method, was low (92% of contaminated products below 1 CFU g(-1)) and growth was limited.
Conclusion: Growth was consistent with results of a predictive model including microbial competition.
Significance And Impact Of The Study: To be included in a quantitative risk assessment.
