To quantify the risk associated with the presence of AFM1 in milk samples (detected/non-detected), the analysis was performed in two stages. First, all variables (general and specific questions) were compared with the dependent variable (bivariate analysis) using T-student test, Mann-Whitney test, c2 or Fisher exact test, considering the characteristic of the independent variable. In second place, logistic regression (multivariable analysis) was performed. The estimation method was maximum likelihood with a convergence criterion of 0.01 to a maximum of 10 iterations. Only variables associated with the dependent variable in the bivariate analysis (P < 0.15) were offered to the model. Colinearity between the selected variables was assessed by calculation of Spearman rank correlations (r). When two potential risk factors were associated (r > 0.6), only one was used in the multivariable analysis (i.e. the one with the smallest P-value in the univariate analysis). All statistical analyses were carried out using InfoStat software
