Introduction and Objectives: In this study the effect of microwave treatment of chicken meat samples which were inoculated with Listeria monocytogeneses (1.6 × 106 cfu/ml) were investigated. Materials and Methods: Drumettes of broiler carcasses were soaked in fully growth of Listeria monocytogeneses in BHI broth. The swab samples were taken from the inoculated samples, after different times of radiation (10, 20, 30, 40, 50, 60, 70 and 80 s), using a domestic microwave oven at full power. Following exposures, viable counts and temperature measurements were performed. The bacterial counts were performed on Listeria Oxford agar. Results: Elimination of Listeria monocytogeneses cells occurred only after 50 s of microwave exposure at 73 °C. Conclusions: The results indicate that short time exposures of chicken portions to microwave heating eliminate Listeria monocytogeneses.
