“…A similar Salmonella prevalence in feedlot cattle had been reported before and been attributed to low hygiene in feedlots (Vanselow et al 2007;Khaitsa et al 2007a). Also, previous reports of Salmonella prevalence in range cattle (Ranta et al 2005) and dairy cattle (Sorensen et al 2003;Huston et al 2002) have been comparable to what is reported by this study, and have been consistently lower than in feedlot cattle.…”

“…However, higher or lower prevalences were reported in calf and cow dairy herds in other countries (Fossler et al 2005;Nielsen et al 2011). The variations in both herd-and individuallevel prevalences reported in different countries reflect the effects of a wide range of different management risk factors (Vanselow et al 2007;Alam et al 2009;Jones 2011). Cattle herds with Salmonella infection may represent the main animal source of Salmonella infection in human.…”

“…Several factors associated with the reduction or the enhancing of Salmonella fecal shedding were reported; type of production system (Vanselow et al 2007), poor hygiene (Boqvist and Vågsholm 2005), large herd size, lack of a clean visitors' parking area (Davison et al 2006), infected neighboring herds, contact with wild birds and rodents, presence of Salmonella carriers (Nielsen et al 2007), contaminated feeds (Jones 2011), use of nipple feeders (Svensson and Jensen 2007), and access to surface water (lake, pond, river, or stream) (Fossler et al 2005) increased the risk of fecal Salmonella spp. shedding in dairy farms.…”

Salmonellosis is an important disease frequently associated with diarrhea in calves. From January to September 2009, a cross-sectional study involving 91 dairy farms was conducted to determine the prevalence of Salmonella spp. infection in cattle in Al-Dhulail Valley, Jordan. A total of 910 calve and cow fecal samples were collected. Information on farm management practices was obtained through personal interviews using a standardized questionnaire and was tested as risk factors for Salmonella spp. positivity in farms by using logistic regression analysis. Standard conventional methods for Salmonella isolation and serotyping were used, and the disk agar diffusion test was used for antimicrobial testing. The herd-level prevalence of Salmonella spp. in calves, cows, and dairy farms was 12, 12, and 23 %, respectively, and the individual-level prevalence was 4 % for calves, cows, and dairy farms. Forty-six percent of the dairy farms had calf diarrhea, and 4 % had cow diarrhea. Seven (17 %) of the 42 farms with calf diarrhea had Salmonella. However, only 7 % (95 % CI: 4, 10) of the 221 diarrheic and 1 % (95 % CI: 0.2, 4) of the 234 of non-diarrheic calves had Salmonella. A total of 33 Salmonella isolates were obtained from the fecal samples: 12 isolates were Salmonella typhimurium, 6 were Salmonella montevideo, 6 were Salmonella anatum, 2 were Salmonella enteritidis, and 7 isolates were not serotyped. All isolates were susceptible to ciprofloxacin, trimethoprim-sulfamethoxazole, gentamycin, neomycin, colisitin, and amoxicillin at 100, 91, 85, 79, 79, and 70 %, respectively. Out of the 11 variables/categories, the frequency of cleaning every 2 months or more was associated with high odds of infection among calves (OR = 5.6) and farms (OR = 7.0).

“…This low incidence in sheep and lambs is consistent with similarly low levels reported overseas. A study of slaughter-age lambs in Australia indicated a prevalence of 0.2% for Salmonella in individual animals (Vanselow et al 2007) and a UK study reported a prevalence of 1.1% for Salmonella spp. in the faeces of sheep at slaughter (Milnes et al 2008).…”

The incidence and prevalence of micro-organisms in ovine faeces as potential sources of diffuse pollution to natural waters were determined. Faecal samples from lambs at slaughter (N 0105) and sheep at pasture (N 0220) were collected. E. coli, enterococci and Campylobacter spp. were enumerated in lambs (6.04 )10 8 , 1.44 )10 7 and 3.3 )10 5 g (1 respectively) and sheep (1.62 )10 7 , 6.8 )105 and 2.08 )10 3 g (1 respectively). Campylobacter spp., Salmonella spp. and Shiga toxin producing E. coli (STEC) were present in 80.9%, 1.9% and 3.8% of lamb samples, and 30.4%, 0% and 0.9% of sheep samples respectively. Cryptosporidium spp. and Giardia spp. were present in 28.6% and 37.1% of the lamb faecal samples, and 3.6% of sheep samples were positive for Cryptosporidium spp. The results of this study will be incorporated into models for estimating the potential impact of ovine faeces on natural waters.

Salmonellaand on‐farm risk factors in healthy slaughter‐age cattle and sheep in eastern Australia

Abstract: Dairy cattle pose the highest risk of all the slaughter-age animals tested. Some of the identified risk factors can be overcome by improved management practices, especially in relation to hygiene.
