- Altogether 496 samples of meat, lymph nodes, process water and swabs from different places in the abattoir were examined for the presence of Listeria spp. L. monocytogenes was isolated from 31 (6%) and other Listeria spp. from 65 (13%) samples L. monocytogenes was isolated from 2 of 10 beef meat samples, 4 of 50 pig meat samples and 1 of 21 lymph nodes of pigs. No Listeria bacteria were isolated from lymph nodes of cattle. The highest percentage of Listeria was recovered from the unclean sections (cattle 22% and pigs 27%) and the highest frequency was observed during the winter months.

Tidskriftsartikel (refereegranskat)abstract
- Altogether 323 pooled samples of neck skins from 1615 broilers from 2 processing plants (A and B) were examined for the presence of Listeria species. The broilers were sampled pre-chilling - after leaving the final rinser but before entering the chiller with chlorinated water - and post-chilling - immediately upon leaving the chiller. Free available chlorine in the chilling water varied from 2 to 15 ppm in plant A and was about 10 ppm in plant B. Listeria monocytogenes was only isolated from broilers in plant A sampled post-chilling (58% of 62 samples). L. innocua was isolated from 19% and 39% of broilers sampled pre-chilling in plants A and B, respectively. Post-chilling, L. innocua was isolated from 3% and 6% of samples from plants A and B, respectively.
