Abstract
The present paper surveys the number of Salmonella isolations in animals and feedstuffs in Sweden during 1988–1992. It is the eighth in a series of reports published by the National Veterinary Institute (NVI) since 1949. During the period referred to, 602 outbreaks of Salmonella were reported in animals, both domestic and wild. Compared with the previous 5-year period there was a 20% reduction in the number of outbreaks (760). Fifty-six different serotypes were reported, 19 of which had never been isolated in any animal in Sweden previously. A temporary increase in the number of outbreaks in poultry was seen in 1991 following an extended sampling before slaughter of layers. A remarkably high prevalence (38%) of Salmonella was observed in snakes in the wild.
In 1990, the end-point testing of feeds was replaced by an approach based on HACCP (Hazard Analysis Critical Control Point) principles for the monitoring of feed mills. Significantly higher number of Salmonella positive samples were found by using this technique compared with the previous analysis of finished feed.
It is concluded that the adopted Salmonella control program has contributed to a reduced number of Salmonella outbreaks in animals in Sweden.
