Chicken liver has been implicated in several reported U.S. illness outbreaks, probably caused by inadequate cooking and pathogen contamination. To identify commonalities among these outbreaks that could represent targets for prevention, we describe chicken liver-associated U.S. outbreaks during 2000-2016 reported to the Food Safety and Inspection Service, to the Centers for Disease Control and Prevention, and in published literature. We identified 28 outbreaks (23 [82.1%] were campylobacteriosis only, 3 [10...

Crononbacter spp. is an opportunistic foodborne pathogen that causes infections in neonates, infants, and immunocompromised adults. Although the contamination of spices with Cronobacter has been previously reported in some countries, there have been no studies on Cronobacter contamination in China. Therefore, this study aimed to investigate the prevalence of Cronobacter spp. in Chinese retail spices. Fifty-six packaged Chinese spices were collected from different markets, and 32 of these were found to be contaminated with Cronobacter...

The contamination of oysters with human norovirus (HuNoV) poses a human health risk, as oysters are often consumed raw. In this study, the effect of high pressure processing (HPP) on a wide variety of HuNoVs naturally present in aqua-cultured Japanese oysters was determined through a polymerase chain reaction-based method with enzymatic pretreatment, to distinguish between infectious HuNoV. Among five batches, genogroup I. genotype 1 (GI.1), GI.2, GI.3, and GI.8 HuNoV were detected from only one oyster not treated with HPP in the fifth batch, while genogroup II...

Norovirus (NoV) is the commonest cause of gastrointestinal disease in the United Kingdom and in many developed countries, causing diarrhea and vomiting in millions of cases worldwide annually. Transmission is most often mediated from person to person. NoV infection has, however, additionally been associated with the consumption of food, either through the consumption of food contaminated at source such as seafood, berries, and salad, or as a consequence of the foodstuff being contaminated in some way by a food handler during processing or serving...

Approximately 20% of U.S. beef cattle receive prophylactic in-feed administration of chlortetracycline (CTC) to reduce bovine respiratory disease (BRD) incidence during the transition into feedlots. To determine the impact of prophylaxis on selected antimicrobial resistance genes (ARGs), 300 beef cattle were placed into 10 pens (30 head/pen). Five "CTC group" pens received in-feed CTC (10 mg/lb of body weight/d) from the fifth to ninth day after feedlot arrival, whereas the five "Control group" pens received no CTC...

Ciprofloxacin, a broad-spectrum fluoroquinolone, is a bactericidal antibiotic targeting DNA gyrase and DNA topoisomerase IV encoded by the gyrA and parC genes. Resistance to fluoroquinolones requires the accumulation of multiple mutations including those that alter target genes and increase drug efflux. To examine the development of fluoroquinolones resistance in Vibrio parahaemolyticus, ciprofloxacin induction and selection was used to obtain several resistant V. parahaemolyticus mutants, which showed decreased susceptibilities to quinolones, and increased or decreased susceptibility to other structurally unrelated antibiotics...

Newport is the third most common Salmonella enterica serotype identified among the estimated 1.2 million human salmonellosis infections occurring annually in the United States. Risk factors for infection and food items implicated in outbreaks vary by antimicrobial resistance pattern. We conducted a descriptive analysis of data from four enteric disease surveillance systems capturing information on incidence, demographics, seasonality, geographic distribution, outbreaks, and antimicrobial resistance of Newport infections over a 10-year period from 2004 through 2013...

Escherichia coli O157:H7 is a human pathogen associated with gastrointestinal disease and hemolytic uremic syndrome. Direct contact with ruminants and their feces at agritourism or livestock interaction events is a known source of transmission. Footbath use is a pathogen reduction strategy that may decrease the transmission of E. coli O157:H7 at these interactions. The efficacy of chemical disinfectants in footbaths is not well reported. Our objective was to determine the susceptibility of E. coli O157:H7 toward commonly used disinfectants in vitro and within contaminated footbaths...

The monophasic variant of Salmonella Typhimurium is highly prevalent in human and in pork. However, little is known about colonization dynamics and serology in pigs. We orally inoculated 24 seven-week-old piglets with 109 CFU/pig of a porcine strain of monophasic Salmonella Typhimurium in an experimental trial. Three groups of eight piglets were orally inoculated and monitored for 21, 49, or 84 days post-inoculation until necropsied. From 3 days post-inoculation to necropsy, individual feces were sampled twice weekly and blood once weekly...

Salmonella serotypes linked to tomato-associated outbreaks were evaluated for survival in soil and water over a 40-day period. Salmonella enterica serotypes Anatum, Baildon, Braenderup, Montevideo, Newport, and Javiana were inoculated separately into sterile soil and water, followed by plating onto TSAYE and XLT4 at 10-day intervals. Biofilm production by Salmonella serotypes was measured on both quartz particles (soil surrogate) and glass coverslips, and was evaluated using a crystal violet dye assay. Salmonella populations in soil and water over 40 days indicated no significant differences between Salmonella serotypes tested (p > 0...
