To investigate Listeria monocytogenes contamination and behaviour in naturally contaminated French cold-smoked salmon (CSS).
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.
Growth was consistent with results of a predictive model including microbial competition.
To be included in a quantitative risk assessment.
调查法国天然污染的冷熏三文鱼（CSS）中单核细胞增生李斯特菌的污染情况及特性。
2001年至2004年间，在法国9家工厂生产的1010包CSS中，有104包检测出单核细胞增生李斯特菌，不同工厂的污染率不同（从0%至41%）。采用灵敏的过滤方法测得初始污染水平较低（92%的受污染产品低于1 CFU g⁻¹），且细菌生长受限。
细菌生长情况与包含微生物竞争的预测模型结果一致。
该研究结果将纳入定量风险评估。
