Zoonoses Action Plan for Salmonella in slaughter-age pigs: how will changes in sampling methods influence estimates of Salmonella?

摘要

In June 2002 the British Pig Executive introduced the Zoonoses Action Plan (ZAP) Salmonella Mon1tonng Programme with the aim of reducing the prevalence of Salmonella Infection in British pigs. A serological screening programme was developed where meat juice samples were collected from p1gs at slaughter and tested using a mix-ELISA and herds were assigned a ZAP score from low to high on the basis of these results. We posed several questions concerning the predictive value of a ZAP score and how this may change if the frequency of sample collection were changed.
