“…A Salmonella surveillance study performed in Taiwan from 2001 to 2005 showed that S. Schwarzengrund and S. Albany were the most prevalent serovars found in chicken meat obtained from wet markets, and all of the chicken meat isolates and human isolates included for comparison were MDR and displayed a high prevalence of resistance to ampicillin, gentamicin, kanamycin, streptomycin, tetracycline, nalidixic acid, trimethoprim-sulfamethoxazole, and chloramphenicol [23] . Studies by comparing the genotypes of isolates from chickens, turkeys, pigs, and humans suggest that the transmission of S. Schwarzengrund from food products to humans is possible [26] , [27] . Our data also show a connection between the S. Schwarzengrund MDR isolates from pigs and humans.…”

We collected 110 Salmonella enterica isolates from sick pigs and determined their serotypes, genotypes using pulsed-field gel electrophoresis (PFGE), and antimicrobial susceptibility to 12 antimicrobials and compared the data with a collection of 18,280 isolates obtained from humans. The pig isolates fell into 12 common serovars for human salmonellosis in Taiwan; S. Typhimurium, S. Choleraesuis, S. Derby, S. Livingstone, and S. Schwarzengrund were the 5 most common serovars and accounted for a total of 84% of the collection. Of the 110 isolates, 106 (96%) were multidrug resistant (MDR) and 48 (44%) had PFGE patterns found in human isolates. S. Typhimurium, S. Choleraesuis, and S. Schwarzengrund were among the most highly resistant serovars. The majority of the 3 serovars were resistant to 8–11 of the tested antimicrobials. The isolates from pigs and humans sharing a common PFGE pattern displayed identical or very similar resistance patterns and Salmonella strains that caused severe infection in pigs were also capable of causing infections in humans. The results indicate that pigs are one of the major reservoirs to human salmonellosis in Taiwan. Almost all of the pig isolates were MDR, which highlights the necessity of strictly regulating the use of antimicrobials in the agriculture sector in Taiwan.

“…The serotypes S. Infantis, S. Newport, and S. Hadar are commonly isolated from poultry and represent potential risks to human health since they have recently been associated with Salmonella outbreaks by direct contact with live birds (Centers of Disease Control and Prevention, 2014). In addition, strains of S. Java and Schwarzengrund have been isolated from chicken meat, presenting pulsed field gel electrophoresis patterns identical to those isolates from humans, strongly suggesting that the poultry carcasses maybe the source of infection (Brown et al 2003;Chen et al 2012).…”

Salmonella enterica is a large group of Gram-negative bacteria responsible for a number of foodborne infections associated with the consumption of contaminated poultry products. The hygienic status of raw chicken meat marketed at Ibague, Tolima, Colombia, is currently unknown. To address this issue, a cross-sectional study was conducted to estimate the prevalence of Salmonella spp., in raw chicken marketed at different outlets in this city. Salmonella spp. was isolated by standard microbiological methods, followed by biochemical, serological, and molecular confirmation. Additionally, risk factors associated with the presence of the bacteria were identified. The prevalence of Salmonella in raw chicken was 17.41% (47/270), and 14 different serotypes were found, out of which S. Paratyphi B (36.17%), S. Hvittingfoss (19.15%) and S. Muenster (10.64%) were the most prevalent and represented 65.95% of all serotypes. Amplification of 284 bp of the invA gene was achieved by PCR in a number of randomly selected isolates. Raw chicken as the only type of meat sold at stores (odds ratio: 2,157, p<0.05), and stainless steel as a contact surface of chicken meat (odds ratio: 13,29, p<0.05), were found to be potential risk factors for the presence of Salmonella in chicken meat. This work serves as a reference about the current status of Salmonella in chicken meat marketed in Ibague, Tolima, Colombia, and indicates the need to establish appropriate control and contingency measures to minimize the presence of the bacteria in raw chicken to prevent its transmission to humans.

“…S. Newport, S. Javiana, S.I4, [5],12:i:-, S. Muenchen, S. Bareilly, S. Monevideo and S. Heildelberg, among others, are also associated in a smaller proportion with human infection (CDC, 2014;Chen et al, 2012). NTS might be responsible for about 80.3 million foodborne illnesses and 115,000 deaths each year in the world (Majowicz et al, 2010), while Typhoid, Paratyphoid and enteric fever cause 25 million infections and 200,000 deaths each year globally (Dekker & Frank, 2015).…”
