Culled beef cows (cows from cow-calf operations that have reached the end of productive life span) and culled dairy cows amount to approximately 18% of the cattle harvested in the U.S. annually, but data on antimicrobial resistance (AMR) levels in U.S. cull cattle is extremely limited. To address this data gap, colon contents were obtained from 180 culled beef cows (conventional beef), 179 culled...

Human noroviruses are enteric pathogens causing a substantial proportion of acute gastroenteritis cases worldwide, irrespective of background variables such as age, ethnicity or gender. Although person-to-person contact is the general route of transmission, foodborne infections are also common. Thorough cooking eliminates noroviruses, but several food products such as berries, leafy vegetables or...

Consumption of contaminated meat and poultry products is a major source of foodborne illness in the United States and globally. Meat inspection procedures, established more than a hundred years ago to detect prevailing food safety issues of the time and largely harmonized around the world, do not effectively detect modern hazards and may inadvertently increase food safety risks by spreading...

Past studies have shown that the on-farm distribution of Listeria monocytogenes is affected by environmental factors (e.g., weather). However, the majority of studies were conducted at large scales (e.g., across farms), while few studies examined drivers of L. monocytogenes prevalence at smaller scales (e.g., within a single field). This study was performed to address this knowledge gap by (i)...

Contaminated poultry meat is a major source of human foodborne illnesses. Many interventions have been developed to reduce and/or eliminate human foodborne pathogens in poultry products; however, treatments with cold plasma or carnosine or a combination of both interventions have not been extensively investigated. In this communication, the bacterial microflora of poultry meat samples after...

Hospital-acquired infections caused by extended-spectrum β-lactamase (ESBL)-producing Escherichia coli are a global problem. Healthy people can carry ESBL-producing E. coli in their intestines; thus, E. coli from healthy people can potentially cause hospital-acquired infections. Therefore, the transmission routes of ESBL-producing E. coli from healthy persons should be determined.A foodborne...

Inhibited reactions have been occasionally observed when cilantro samples were processed for the detection of Cyclospora cayetanensis using real time PCR (qPCR). Partial or total inhibition of PCR reactions, including qPCR, can occur leading to decreased sensitivity or false negative results. If inhibition occurs, this implies the need for additional purification or clean-up treatments of the...

There is increasing evidence that diversity changes in bacterial communities of beef cattle correlates to the presence of Shiga toxin-producing Escherichia coli (STEC). However, studies that found an association between STEC and bacterial diversity have been focused on pre-slaughter stages in the beef supply chain. This study was designed to test a hypothesis that there is no differences in...

High moisture slurries used in production of table spreads may permit growth of  Staphylococcus aureus and  Bacillus cereus  and subsequent production of heat stable enterotoxin. Compliance with the Food Safety Modernization Act (FSMA), specifically 21 CFR Part 117, Subpart B and Section 117.8 (c)(2) and (c)(3) requires a hazard analysis to determine if preventive controls are needed. In this...

To reduce the number of potential S. aureus contaminated cheese reaching consumers, European legislation stipulates that all cheese must be tested for coagulase-positive staphylococci (CPS) at the point in production when numbers are expected to be highest. If CPS counts exceed 105 CFU/mL, enterotoxin tests must be conducted. In the case the enterotoxin test shows positive results the cheese must...

Umai  is a popular, traditional, native dish of the Melanau ethnic group in Sarawak. It is prepared using thin slices of raw marine fish marinated with calamansi juice and seasoned with other ingredients. The local people believe that the acidity of the citrus juice along with the use of salt and spice, can slightly cook the fish and remove the fishy smell. The aim of the study was to investigate...

Infant formula is a major source of food and nutrition for infants and toddlers. However, the presence of contaminants, such as toxic metals, may pose increased health risks to infants. An investigation on the occurrence of the metals: aluminum (Al), barium (Ba) and chromium (Cr), in baby formulae marketed in Lebanon was performed. Infant formula samples were collected from all the brands (n=39)...
