Background and Aim : Today, studies have shown that a relationship is found between the presence of remaining pesticides in food and the health problems. Milk is one of the most widely consumed drinks in today's communities. Preparing mixed drinks by adding ingredients such as carrots to milk can encourage individuals to consume this healthy drink. Permethrin is widely used in agriculture.Methods : In this study, we have investigated the effect of adding lactobacillus casei on the reduction of permethrin in milk/carrot juice mix drink. Milk/carrot juice mix drink was prepared by adding ۷% carrots, sugar and pectin to the sterilized milk. ۱۵ logcfu / ml of Lactobacillus casei was added to the drink and the samples were stored in the refrigerator for ۲۱ days. The level of permethrin and the number of bacteria were determined on days ۱, ۷, ۱۴ and ۲۱ with ۳ replications. The level of permethrin was determined by the high-performance liquid chromatography method.Results : The results showed that on day ۲۱, ۳۳.۹% reduction was observed in the level of permethrin.Conclusion : It seems that the adding lactobacillus casei to the drink with carrot can be reduced the amount of permethrin.
