An exposure assessment was conducted to quantitate tetracyclines (TCs) in chickens and the risk estimates were calculated using deterministic and probabilistic approaches. The results revealed that through deterministic approach, estimated daily exposure to TCs resulted in children aged 1<y<3 and 4<y<6 (0.05919 and 0.03946 μg/kg bw/day), followed by adults (0.02847 μg/kg bw/day) and children aged 7<y<10 at 0.02631 μg/kg bw/day. Based on the probabilistic approach, dietary exposure of Malaysian adults to TCs was estimated to range from 0.00174–0.35209 μg/kg bw/day. In comparison, for the children group, the estimated exposure was higher in age 1<y<3 at 0.0137 – 1.9845 μg/kg bw/day followed by children aged 4<y<6 and 7<y<10 at 0.00718 – 1.3967 μg/kg bw/day and 0.00834 – 0.91841 μg/kg bw/day respectively. However, the estimated risk calculated for all groups was <10 % ADI. These indicate that toxicological risk with regard to the consumption of chicken meat could not be considered as a public health problem, but the result can be supportive for the safety authorities to engage policies in managing any potential risk. The occurrence of high concentration of TCs residues in small samples still warrants closer monitoring and management of the use of TCs in chicken farms in Peninsular Malaysia.
