Salmonella enterica is a human pathogen with over 2,500 serovars characterized. S. enterica serovars Choleraesuis and Paratyphi C are two globally distributed serovars. We have developed a rapid molecular-typing method to detect serovars Choleraesuis and Paratyphi C in food samples by using a comparative-genomics approach to identify regions unique to ...

Melamine, a nitrogen-rich chemical, was implicated in pet and human food recalls in 2007, which caused enormous economic losses to the food industry. In this study, melamine concentration in wheat gluten, chicken feed, and processed foods (that is, cake and noodle) was measured by surface enhanced Raman spectroscopy (SERS) in ...

In Japan, the numbers and cases of food poisonings must be reported as required by the Food Sanitation Law. This paper focuses on Salmonella, one of the leading food-borne pathogens in Japan, and it analyses the reported food poisoning data to assess the nature of Salmonella-associated food-borne disease. Obviously, these ...

Farmers around the world have been urged to eliminate barn swallows (Hirundo rustica) from their buildings, based on the unproven assumption that these birds amplify and spread Salmonella to livestock, humans, and stored food. However, we tested over 500 barn swallows in Sweden and found no evidence that they carry ...

From February to November 2007, chicken meat preparations (n = 656) were sampled at 11 processing companies across Belgium. All samples were tested for Campylobacter by enrichment culture and by direct plating according to standard methods. Almost half (48.02%) of the samples were positive for Campylobacter spp. The mean Campylobacter ...

A qualitative exposure assessment for Salmonella in eggs produced on the island of Ireland was developed. The assessment was divided into three main modules (production and packing, distribution and storage, and preparation and consumption), and each of these stages into defined steps in the exposure pathway. In the production and ...

Campylobacter jejuni is the most common cause of bacterial gastroenteritis worldwide, with contaminated chicken meat considered to represent a major source of human infection. Biosecurity measures can reduce C. jejuni shedding rates of housed chickens, but the increasing popularity of free-range and organic meat raises the question of whether the ...

There has been a growing niche-market, outdoor, antimicrobial-free (ABF) swine production system in the last few years prompted by consumers' demand for a more "natural" pork product. The impact of such production systems on reemergence of current and historically significant swine-associated pathogens has not been determined. The objectives of the ...

Campylobacter infections pose a serious public health problem in Belgium. Poultry meat is most likely responsible for 40% of human campylobacteriosis cases in Belgium. On a yearly basis, consumption of poultry meat causes at least 22,000 campylobacteriosis cases, with a cost of illness of Euro 10.9 million. Several intervention measures ...

Few developing countries have foodborne pathogen surveillance systems, and none of these integrates data from humans, food, and animals. We describe the implementation of a 4-state, integrated food chain surveillance system (IFCS) for Salmonella spp. in Mexico. Significant findings were 1) high rates of meat contamination (21.3%-36.4%), 2) high rates ...

Of more than 2500 identified Salmonella serotypes, only a small proportion are common in poultry flocks. However, there is an epidemiologically important connection between poultry products and human infections because many of the serotypes that are most prevalent in humans (such as Salmonella Typhimurium and Salmonella Enteritidis) are similarly common ...

We have investigated the influence of post-filtering virtual screening results, with pharmacophoric features generated from an X-ray structure, on enrichment rates. This was performed using three docking softwares, zdock+, Surflex and FRED, as virtual screening tools and pharmacophores generated in UNITY from co-crystallized complexes. Sets of known actives along with ...

Salmonellosis is an important disease in humans and is associated with contaminated food, including pork products. Salmonella infection is invasive in humans, but it usually remains latent within the swine population, creating reservoirs for carcass contamination. Although abattoirs implement stringent procedures during carcass processing, some raw pork products still have ...

Raw seed sprouts have been implicated in several food poisoning outbreaks in the past 10 years. The U.S. Food and Drug Administration recommends that sprout growers use interventions (such as testing of spent irrigation water) to control the presence of pathogens in the finished product. During the sprouting process, initially ...

Campylobacter and Salmonella species and Shiga toxin-producing Escherichia coli (STEC; the majority of which are type O157:H7) efficiently enter the human food chain from infected or colonized animals. Poultry contamination with Campylobacter and/or Salmonella species and produce contamination with STEC have become major public health challenges. The global food supply, ...

Domestic food contact surfaces can play an important role in the transmission of foodborne disease, yet debate continues as to which surface materials pose the greatest risk to consumer health in terms of cross-contamination during food preparation. Salmonella Typhimurium was inoculated onto stainless steel, Formica, polypropylene, or wooden surfaces (25 ...
Muldoon Mark T - - 2007
Immunochemical-based methods for the detection of Salmonella in food can be complicated by the presence of closely related, immunocrossreactive non-Salmonella species in the sample that may cause false-positive results. To circumvent this problem, specific bacteriophages against immunocrossreactive, non-Salmonella bacteria were used in the sample enrichment step to suppress their growth ...
Little C L - - 2007
This survey was prompted by a change in the epidemiology of Salmonella Enteritidis infections in England and Wales and elsewhere in Europe and, to our knowledge, is the first survey to provide information on Salmonella contamination of non-United Kingdom eggs on retail sale. Based on 10,464 non-United Kingdom eggs (1744 ...

Controlling Salmonella in integrated broiler operation is complicated because there are numerous potential sources of Salmonella contamination, including chicks, feed, rodents, wild poultry operations, and the processing plant. The objective of this study was to investigate the distribution of Salmonella through all phases of two integrated broiler operations and to ...
Varela Norma P - - 2007
This study aimed to establish the prevalence of Campylobacter spp. in 80 Ontario grower-finisher pig herds. Ninety-nine percent of the isolates yielded Campylobacter, C coli being the most common species detected. Control of this microorganism must rely on careful food processing and storage of pork, rather than on an on-farm ...
