Abstract: This study is conducted to identify the factors which contribute to excess iodine in bulk milk tanks on Canadian dairy farms. Previous studies showed important variability in iodine content in milk in Canada (Borucki Castro et al., 2012, 2010). To prevent iodine excess in milk, Health Canada suggested an interim upper limit on milk iodine concentration of 500µg/liter. In this study, a questionnaire in both French and English was sent to 3,180 dairy farmers from four provinces from Canada and an ordered logistic model was then fitted. Results indicate that the farm management practices as well as dairy producers’ attitudes contribute to iodine excess in bulk milk tanks on Canadian dairy farms. These results are interesting for the designing of adequate programs to reduce the iodine residue variability in milk in the framework of the ongoing project «Understanding and Controlling Variability in Bulk Milk Iodine in Canada».
