“…Infected domestic and non‐domestic animals are potential sources of human Campylobacter and Salmonella infections. Human campylobacteriosis and salmonellosis acquired from animals colonized and shedding Campylobacter and Salmonella can be categorized into three types: (a) infections acquired from the consumption of contaminated animal products such as meat or eggs (Bertasi et al, ; Marshall et al, ; Nielsen, Fussing, Engberg, Nielsen, & Neimann, ; Schildt, Savolainen, & Hanninen, ); (b) infections acquired from close contact with infected animals (Behravesh, Brinson, Hopkins, & Gomez, ; Gaffga et al, ; Gras et al, ); and (c) infections acquired from environments contaminated with faeces from infected animals shedding bacteria. Although the environment is the main source of Campylobacter and Salmonella contamination of animal foods due to unhygienic handling, the potential of accidental intestinal contents spillage and extra‐gastrointestinal colonization as a source of contamination should not be underestimated (Humphrey & Williams, ).…”

Livestock meat and offal contribute significantly to human nutrition as sources of high‐quality protein and micronutrients. Livestock products are increasingly in demand, particularly in low‐ and middle‐income settings where economies are growing and meat is increasingly seen as an affordable and desirable food item. Demand is also driving intensification of livestock keeping and processing. An unintended consequence of intensification is increased exposure to zoonotic agents, and a contemporary emerging problem is infection with Campylobacter and Salmonella spp. from livestock (avian and mammalian), which can lead to disease, malabsorption and undernutrition through acute and chronic diarrhoea. This can occur at the farm, in households or through the food chain. Direct infection occurs when handling livestock and through bacteria shed into the environment, on food preparation surfaces or around the house and surroundings. This manuscript critically reviews Campylobacter and Salmonella infections in animals, examines the factors affecting colonization and faecal shedding of bacteria of these two genera as well as risk factors for human acquisition of the infection from infected animals or environment and analyses priority areas for preventive actions with a focus on resource‐poor settings.

“…While five of six S. Newport outbreaks identified in France have now been associated with raw goats' milk cheeses, we are not aware of any particular affinity between this serotype and goats or dairy products. Elsewhere the sources in S. Newport outbreaks have been eclectic, including fresh produce (fruits, leafy, root and vine-stalk vegetables, sprouts, nuts) [18][19][20][21][22][23][24], ground beef [25,26] and other animal-derived foods [27], suggesting varied reservoirs. Two other outbreaks linked to consumption of raw milk cheeses have been reportedboth were in the USA and associated with unpasteurised cows' milk cheeses [28,29].…”

Outbreak of Salmonella Newport associated with internationally distributed raw goats' milk cheese, France, 2018

Raw milk cheeses are commonly consumed in France and are also a common source of foodborne outbreaks (FBOs). Both an FBO surveillance system and a laboratory-based surveillance system aim to detect Salmonella outbreaks. In early August 2018, five familial FBOs due to Salmonella spp. were reported to a regional health authority. Investigation identified common exposure to a raw goats' milk cheese, from which Salmonella spp. were also isolated, leading to an international product recall. Three weeks later, on 22 August, a national increase in Salmonella Newport ST118 was detected through laboratory surveillance. Concomitantly isolates from the earlier familial clusters were confirmed as S. Newport ST118. Interviews with a selection of the laboratory-identified cases revealed exposure to the same cheese, including exposure to batches not included in the previous recall, leading to an expansion of the recall. The outbreak affected 153 cases, including six cases in Scotland. S. Newport was detected in the cheese and in the milk of one of the producer's goats. The difference in the two alerts generated by this outbreak highlight the timeliness of the FBO system and the precision of the laboratory-based surveillance system. It is also a reminder of the risks associated with raw milk cheeses.

“…Salmonella is a main foodborne pathogen worldwide which causes an annual death of 230,000 due to foodborne disease [1]. Salmonella is also a common cause of foodborne outbreaks and transmitted by contaminated food such as beef, pork, tomato, and cucumbers [2][3][4][5]. Salmonella is prevalent throughout the year, but it was reported the most commonly detected between April and October in China [6].…”

Background : Salmonella is one of the main causative agents of diarrhea which results in substantial disease burden. To determine the prevalence, serotype distribution, and antimicrobial resistance profiles of clinical Salmonella isolates in Shenzhen, a 6-year surveillance study was conducted. Methods: Three sentinel hospitals were chosen and patients who visited the gastroenteritis clinics with acute diarrhea were enrolled. Salmonella isolates from the stool samples were subjected to serotyping, antimicrobial susceptibility testing to 24 antibiotics, and detection of resistance genes. Results: A total of 297 (5.7%) Salmonella strains were isolated from stool samples from 5,239 patients. Among the 42 serovars identified, serovar Typhimurium was the most common serotype which represented 39.7% of the isolates (118), followed by serovar Enteritidis (71, 23.9%), London (12, 4.0%), 4, 5, 12: i: - (11, 3.7%), and Senftenberg (8, 2.7%). A high frequency of resistance was found in ampicillin (70.6%), piperacillin (64.5%), tetracycline (63.5%), and streptomycin (54.3%). Resistance to ampicillin and tetracycline was observed in 95.3% of S. Typhimurium isolates; and nalidixic acid in 93.1% of S. Enteritidis isolates. Resistance to 5 or more antimicrobial agents was found in 78.8% of S. Typhimurium and 69.0% of S. Enteritidis isolates. Conclusions: Salmonella is an important cause of acute gastroenteritis and a broad range of serotypes are prevalent in Shenzhen, with Enteritidis and Typhimurium being the most common serovars. The high level of antibiotic resistance is of public health significance and ongoing monitoring combined with rational use of antibiotics are recommended.
