据欧盟食品安全局（EFSA）消息，8月12日欧盟食品安全局发布2010-2011年度部分即食食品中李斯特菌基线调查分析B部分内容：流行情况相关因素与探索合规性分析。
欧盟食品安全局采用多因素分析法（广义估计方程），研究了基线调查过程中所得几个因素与两个结果的统计学关联性。这两个结果为：李斯特菌流行情况与数量超过100cfu/g的肉、鱼样本比例。另外还运用了统计学模型对超过100cfu/g的样本比例进行了分析。
部分原文报道如下：
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.
