| Abstract: | This survey describes the frequency of Salmonella in animals and feedstuffs isolated in Sweden 1983-1987. Since 1949 National Veterinary Institute (NVI) has published such reports every fifth year. During the period of this report 760 outbreaks of Salmonella were reported in animals. This includes both domestic and wild animals. The corresponding figure for the previous period was 1266 outbreaks. 56 different serovariants were reported, 17 of these were new to Sweden. In cattle and swine there were a decrease of outbreaks. In poultry 86 outbreaks were reported, compared with 220 outbreaks during the previous five-year period. Swedish feed producing plants are checked both voluntary and compulsory, for the presence of Salmonella in raw materials, scrape and dust samples and compound feed. During 1983-1987 a total of 236 strains at Salmonella were isolated. This is the lowest incidence found during the last 15 years. All consignments of feedstuffs of animal origin intended for import to Sweden has to be examined for the presence of Salmonella. During 1983-1987 8.6% of the consignments were positive for Salmonella and were thus not allowed to be used in Sweden. |
