In the extensive ABF pig production system, pigs were reared in open fields in a barricaded area and had free access to the environment including soil and water. Under the intensive system, pigs were reared in confined barns with concrete slatted floors. A total of five finishing farms were sampled from each system over a period of 2 years from 2002 to 2004. Pigs from the two ABF systems were slaughtered at two different slaughter plants. The intensively reared pigs were slaughtered in a slaughter plant with a blast chiller system for cooling the carcass in 2 h with a temperature of –30C. The extensive pigs were slaughtered in a smaller plant using overnight chilling to cool the carcass (1–4C for ~18 h).

At every farm visit, we sampled 30 pigs and collected ~10 g of fresh faecal samples per rectum with gloved hands. Carcasssamples were collected using sterile swabs soaked in 10 mL of buffered peptone water (Becton Dickinson, NJ, USA). Ten individual carcass samples were collected at each of the three processing stages: preevisceration, post-evisceration and post-chill. Carcass samples were collected by swabbing at the jowl, belly and the ham region.
