Abstract
The goal of this research was to establish the occurrence of Listeria monocytogenes in several points of meat processing plants such as 01 slaughterhouse and 05 butcher's shops sited at north region of Paraná State. The United States Department of Agriculture (USDA) isolation methodology of Listeria spp. was used in 124 samples of equipments/utensils and environmental sources, with species identification by biochemical tests and confirmation by API Listeria (bioMérieux). The results showed frequencies of 6,25% for L. monocytogenes; 68,75% for L. innocua; 18,75 for L. welshimeri; 4,17% for L. seeligeri and 2,08% of L. grayi. The positive samples for L. monocytogenes were equipments of butcher's shops, as plastic boxes and tendering machine.
