The spread of salmonellas during the slaughtering of cattle in the Berlin (West) slaughterhouse was investigated. The slaughterline was divided into 12 areas. During the first examination, which lasted eight months, the equipment and implements a t each stage of slaughter, and faeces of cattle were tested. Salmonellas were not isolated from any of the 226 samples of faeces whereas 14 isolations (1.8%) were made from the 768 swabs taken from equipment. Most isolates were obtained within the step of opening the abdominal cavity.In a second survey 61 (4.3%) of 1392 swab samples and 2 (0.75%) of 267 faeces samples were positive. Of the different processing steps, cutting off the hooves and loosening the skin of legs gave the highest recovery of salmonellas. Moderate recoveries were obtained after opening the abdominal cavity. Removal of head, loosening the skin of head, removing the hide and splitting the breastbone and the carcass did not result in the isolation of the organism. Salmonella anaturn was the most common isolate. The same serotypes were isolated from both carcasses and equipment.

“…The isolation of the same Salmonella strain from hands, clothes, tools and the carcasses indicate that the transmission might have been from animal to man or may have been from hide to tool and to carcass. The incidence of surface contamination agrees with those of other workers (Goo et al 1973;Nazer and Osborne 1976).…”

“…Contamination of red meat by salmonellae occurs at the abattoirs as there is no effective means of detecting symptomless excretors. Meat may be contaminated from such animals and salmonellae can gain access to the meat at any stage in butchering (Norval 1961). Their occurence in both, the equipment and carcasses has been well established (Nottingham et al 1974;Peel and Simmons 1978;Smeltzer et al 1980a;Stolle 1981).…”

This paper presents information on the incidence of contamination in the slaughterhouse of Berlin (West) in which cattle from the German Democratic Republic, Poland, Bavaria and the northern part of the Federal Republic of Germany were slaughtered and emphasizes the aspects of different enrichment steps.…”

The spread of salmonellae in the abattoir environment during the slaughtering of cattle in the Berlin (West) slaughterhouse was investigated. A total of 99 (3.66%) out of 2704 swab samples were positive. Cutting off the hooves andpreskinning gave the highest recovery of salmonellae. Less recoveries were obtained aJier opening the abdominal cavity. Removal of head, loosening the skin of head, removing the hide and splitting the breastbone and the carcass did not result in the isolation of the organism. Salmonella anatum was the most common isolate. The same serotypes were isolated from both carcasses and equipment.A comparison between Tetrathionate-enrichment (Z' E) and Cystine-Seleniteenrichment (CSE) was made with 2 different pre-enrichment periods (6 h and 24 h); this was done with swab samples from red meat carcasses and slaughterhouse equipment. Overall, iTE had a higher isolation rate at 24 h preenrichment. The variation between enrichment media may be partly attributable to the multiple swab sampling technique used in the study.

“…Among retail unweaned veal samples from New Zealand, 0.5% (1 of 183 samples) were positive for Salmonella (47). Similar results were observed in the Canadian federal abattoir study, with 4% (11 of 267) of veal carcasses and 3% (17 of 666) of beef carcasses being contaminated with Salmonella, and 4.3% (31 of 720) of veal carcasses from United Kingdom slaughterhouses were contaminated (20,28). Higher Salmonella prevalences were reported in a 2005 Iranian slaughterhouse study: 25% in roast beef, 19% in veal, and 12% in beef (25).…”

This study estimated the prevalence of Salmonella, Campylobacter, and Escherichia coli isolates in fresh retail grain-fed veal obtained in Ontario, Canada. The prevalence and antimicrobial resistance patterns were examined for points of public health significance. Veal samples (n = 528) were collected from February 2003 through May 2004. Twenty-one Salmonella isolates were recovered from 18 (4%) of 438 samples and underwent antimicrobial susceptibility testing. Resistance to one or more antimicrobials was found in 6 (29%) of 21 Salmonella isolates; 5 (24%) of 21 isolates were resistant to five or more antimicrobials. No resistance to antimicrobials of very high human health importance was observed. Ampicillin-chloramphenicolstreptomycin-sulfamethoxazole-tetracycline resistance was found in 5 (3%) of 21 Salmonella isolates. Campylobacter isolates were recovered from 5 (1%) of 438 samples; 6 isolates underwent antimicrobial susceptibility testing. Resistance to one or more antimicrobials was documented in 3 (50%) of 6 Campylobacter isolates. No Campylobacter isolates were resistant to five or more antimicrobials or category I antimicrobials. E. coli isolates were recovered from 387 (88%) of 438 samples; 1,258 isolates underwent antimicrobial susceptibility testing. Resistance to one or more antimicrobials was found in 678 (54%) of 1,258 E. coli isolates; 128 (10%) of 1,258 were resistant to five or more antimicrobials. Five (0.4%) and 7 (0.6%) of 1,258 E. coli isolates were resistant to ceftiofur and ceftriaxone, respectively, while 34 (3%) of 1,258 were resistant to nalidixic acid. Ciprofloxacin resistance was not detected. There were 101 different resistance patterns observed among E. coli isolates; resistance to tetracycline alone (12.7%, 161 of 1,258) was most frequently observed. This study provides baseline prevalence and antimicrobial resistance data and highlights potential public health concerns.
