Antibiotics are one of the most important drugs in large animal veterinary practice. However, antibiotics and especially β-lactam can be found as residues in different animal products particularly in milk from treated cows. The present survey was conducted between July 2016 and June 2017 in four governorates from Northern Tunisia, namely Jendouba, Béja, Kef and Siliana. A total of 10.699 bulk cow’s milk samples were collected and tested for the presence of β-lactam residues using the Penzym® test. Among them, 14 were positive. Even if the contamination rate was low (0.13%), the quantity of refused milk due to presence of β-lactam residues was relatively high (102.103 L) which represents 2.6% of the total volume of refused milk (3.874.103 L). Milk samples collected from the Kef governorate showed the highest proportion of antibiotic residues (0.64%), followed by the governorate of Béja (0.13%) and the governorate of Jendouba (0.07%).The presence of β-lactam residues in milk represents a real threat to animal and human health, systematic monitoring could be implemented in Tunisia for all milk productions in order to reduce these risks.
