食品伙伴網(wǎng)訊  據(jù)歐盟食品安全局（EFSA）消息，8月12日歐盟食品安全局發(fā)布2010-2011年度部分即食食品中李斯特菌基線調(diào)查分析B部分內(nèi)容：流行情況相關(guān)因素與探索合規(guī)性分析。

    歐盟食品安全局采用多因素分析法（廣義估計(jì)方程），研究了基線調(diào)查過程中所得幾個(gè)因素與兩個(gè)結(jié)果的統(tǒng)計(jì)學(xué)關(guān)聯(lián)性。這兩個(gè)結(jié)果為：李斯特菌流行情況與數(shù)量超過100cfu/g的肉、魚樣本比例。另外還運(yùn)用了統(tǒng)計(jì)學(xué)模型對超過100cfu/g的樣本比例進(jìn)行了分析。

    部分原文報(bào)道如下：

    A European Union-wide baseline survey on Listeria monocytogenes was carried out in 2010 and 2011. Packaged （not frozen） hot or cold smoked or gravad fish, soft or semi-soft cheeses （excluding fresh cheeses） and packaged heat-treated meat products were sampled in 26 European Union Member States and in one country not belonging to the European Union.

    Multiple-factor analysis （Generalized Estimating Equations） was used to investigate the statistical association between several factors on which information was gathered during the baseline survey, and two outcomes: prevalence of Listeria monocytogenes and proportion of samples with counts exceeding 100 cfu/g.

    Furthermore, a statistical model was developed that allowed the use of estimates of the proportion of samples with an L. monocytogenes count > 100 cfu/g obtained from a single-unit sample survey of a population of RTE foods.
