The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.

Abstract

Bacteriological examinations for Salmonella in meat cutting plants constitute an important cornerstone in the Styrian Salmonella surveillance programme for pork production. A total of 1920 bulk wipe samples were tested in 1999. Salmonella was detected in 7 samples taken prior to retail cutting (n = 720), in one sample taken after retail cutting (n = 720) and in one of the swab samples collected from cutting surfaces (n = 480). The extrapolation from the random sample to the population of pork produced and cut in Styria showed the estimated average proportion p , of Salmonella contaminated pork to be 0.15 % S = 95 %; CI 0.12 % SpS 0.18 %. Based on these results sampling was restricted to wholesale cuts and carcass halves from 8 slaughterhouses and meat cutting plants in 2000. Testing a total of 1290 bulk wipe samples Salmonella were detected in three cases (p= 0.14%, S = 95 %; CI 0.17% SpS 0.25 %). This favourable situation, which was corroborated by serological examinations of finishing pig herds, does not indicate an urgent call for action in Styrian breeding and finishing establishments.
