[Evaluation of the sampling plan for a Salmonella monitoring program for slaughter pigs]

In the setting of the Salmonella monitoring programme of the Federal Republic of Germany the sampling plan does not take into account prevalences occuring in reality. Hence, in most farms the testing effort will increase. This particularly applies to pig farms up to 100 fatteners, for which the proportion of animals to be tested is too high. Besides, the threshold values determing the allocation to the three quality categories, less than 20%, 20-40%, and more than 40% Salmonella positive fatteners, are also chosen too high.
