“…The Salmonella serovars which were isolated in the feed‐mills were also those most widely distributed throughout the broiler flocks. Persistent contamination in the feedmills may not be readily detected by monitoring the finished products and ingredients because their contamination may be intermittent (Eld and others 1991, Malmqvist and others 1995, Davies and Wray 1997). Company A did monitor the feedmill and was aware that the cooler was contaminated, whereas company B only monitored the ingredients and the finished products and was not.…”

Observations on the distribution and control of Salmonella species in two integrated broiler companies

et al. 2001

The effectiveness of cleaning and disinfecting broiler farms and the persistence of Salmonella species in two integrated broiler companies was investigated for two years. Both companies used a cleaning and disinfection regime which included the application of a spray of phenolic disinfectant followed by fogging with formaldehyde solution, and this was highly effective in preventing carry-over of infection in the broiler houses. The disinfection of service areas and areas outside the houses was less effective but it had no influence on the Salmonella status of later flocks. Both companies had persistent problems with the contamination of pellet cooling systems in their feedmills with Salmonella 4, 12:d:- in company A, and with Salmonella binza and Salmonella ohio in company B. The hatcher incubators of both companies were also persistently contaminated with Salmonella livingstone and Salmonella thomasville in company A and with Salmonella senftenberg in company B. At both companies sites Salmonella enteritidis and Salmonella typhimurium Tr104 were also isolated occasionally from various locations.

“…Since 1990, it has varied between six and 14 cases per 100,000 inhabitants. The prevalence of Salmonella among Swedish food‐producing animals is extremely low (Mårtensson and others 1984, Eld and others 1991, Malmqvist and others 1995, Wahlström and others 1997, Anon 2001) and it is rarely found in Swedish wildlife. However, Salmonella infection is not uncommon in small passerine birds, and may cause clinical, sometimes fatal, infections, mainly during winter and early spring probably in association with their congregation at feeding stations (Hurvell and Jevring 1974, Mörner 1991).…”

Survey ofCampylobacterspecies, VTEC 01 57 andSalmonellaspecies in Swedish wildlife

et al. 2003

Samples collected from 791 wild animals (Canada geese, roe deer, hares, moose, wild boar and gulls) shot during hunting were examined for verocytotoxin-producing Escherichia coli (VTEC) O157, and thermophilic Campylobacter and Salmonella species. With the exception of one positive isolate from a wild boar, VTEC O157 was not isolated from any of the animals. Salmonella species were isolated only from the gulls, of which 4 per cent were estimated to be positive. Thermophilic Campylobacter species were commonly isolated from all the species except deer.

“…Foodborne infections caused by Salmonella in Sweden are rare and the presence of Salmonella in domestic animals is extremely low. (NVI Thal et al 1957, Rutqvist & Thal 1958, Karlsson et al 1963, Hurvell et al 1969, Gunnarsson et al 1974, Sandstedt et al 1980, Martensson et al 1984, Eld et al 1991, have become valuable instruments in the evaluation and control of Salmonella in this country. By provisions issued by the Swedish Board of Agriculture (SBA), all isolations of Salmonella must be identified and reported to SBA as well as to the State Epizootiologist.…”
