Welcome to the page about Food safety of Engormix; a source of knowledge on Food safety.
This award is given to stimulate and reward research in the field of poultry (chicken, turkeys and eggs) pre- and post-harvest food safety. Nominee’s research should exhibit a sustained impact on decreasing pathogenic organisms in pre- and post-harvest situations. It is given every other year.

Introduction: The cross-contamination of non-medicated feed with residues of antimicrobials causes a public and animal health concern associated with the potential for selection and dissemination of resistance in commensal and potentially zoonotic bacteria. To identify the extent of the situation, we built a model that provides a way to estimate the percentage of cross-contaminated pig feed in total and per different levels at which cross-contamination may occur (i.e....

With mycotoxins on the rise, food safety and authenticity expert Michele Suman looks at how to deploy tandem mass spectrometry for mycotoxin quantification
Mycotoxin contamination seriously threatens the safety and stability of global food chains. Produced by fungi, these potentially toxic secondary metabolites affect a broad range of foodstuffs,...

Wheat—the most widely cultivated crop in the world—is under growing attack from harmful toxins. Across Europe, almost half of wheat crops are impacted by the fungal infection that gives rise to these toxins, according to a study led by fungal biologist Dr. Neil Brown from the U.K.'s University of Bath, in collaboration with colleagues at the University of Exeter.
These troublesome "mycotoxins" are produced by the fungus that causes Fusarium Head Blight, a disease that...

Introduction: Pork head meat, cheek meat, lymph nodes, and other carcass by-products may become contaminated with Salmonella in pork slaughter facilities. In a preliminary survey, a large pork processing plant in the United States was sampled bimonthly from January to July of 2015 to determine the prevalence, seasonality, and serotype diversity of Salmonella enterica (SE) isolated from cheek meat and head trim of swine carcasses. Materials and...

Introduction Aflatoxins are toxic, secondary metabolites synthesized by some fungi species in the genus Aspergillus, mainly those belonging to the species A. flavus, A. nomius, and A. parasiticus (Ismaiel et al., 2020). Aflatoxins are considered the most important mycotoxins, given their carcinogenic and hepatotoxic effects on animals and humans (Bhat et al., 2010). Among several types of aflatoxins, the most frequent ones found as natural contaminants of foodstuffs are aflatoxins...

Introduction The “traditional” approach to food quality and safety management is based on end-product testing. However, end-product testing provides only very limited information about the safety status of a food. The food safety crisis of the 1990s (Listeria, Salmonella, Escherichia coli, Campylobacter, dioxins, antibiotics, acrylamide, etc.) highlighted the failure of this traditional approach. If a dangerous organism is found, it means something; but its absence...

Poultry researchers show there’s no safe amount of moldy corn
Poultry scientists are taking a close look at moldy corn in an effort to better protect animal and human health. In a recent study, published in Poultry Science ® , researchers measured bird performance and examined mycotoxin levels when laying hens were fed different amounts of moldy corn.
Mycotoxin are toxins made by...

Aflatoxins are fungal metabolites—mainly produced by Aspergillus flavus and Aspergillus parasiticus living in soil—that contaminate crops throughout growth, harvest, storage, transportation, and processing. Aflatoxin B1 is not only the most potent natural carcinogen known, but also the most commonly produced toxic strain. As of 2010, roughly 5 billion people worldwide were estimated to be exposed to high levels of aflatoxins. High consumption levels can result in aflatoxicosis,...

Introduction On August 28, 2021, the United States Department of Agriculture (USDA) confirmed that African swine fever virus (ASFV) had been diagnosed in the Dominican Republic (https://www.aphis.usda.gov/aphis/newsroom/news/sa_by_date/sa-2021/asf-confirm). This poses a tremendous threat to the swine industry of the United States (U.S.) given the proximity to the mainland. When ASFV emerged in China, the virus was able to move rapidly and easily throughout the country due to movement...

Introduction The link between diet and disease transmission has raised concerns that U.S. herds could become infected with foreign pathogens through contaminated feed and feed ingredients originating from countries with endemic disease and lax sanitation and quality assurance procedures. Experimental data has already demonstrated that some feed ingredients, particularly soy-based products, can support the viability of at least three significant viral pathogens of swine (i.e.,...

Salmonella is a leading bacterial cause of foodborne illness, with ~17% of salmonellosis cases attributed to broilers. Conventional Salmonella isolation procedures involve characterizing a single colony per positive sample. As such, these methods favor the most abundant serovar found in a sample, potentially allowing other serovars to remain undetected. CRISPR-SeroSeq is a novel, high-resolution sequencing approach that can detect and quantify the relative frequency of multiple serovars...

A veterinarian’s perspective on AMR and sustainable animal agriculture One of the landmark scientific achievements of the 20th century has been the discovery of antibiotics. Antibiotics have revolutionized healthcare and have helped healthcare professionals save precious human and animal lives for centuries. However, antibiotics have now become victims of their own success. Due to their non-judicious and blind use, we now face a widespread...

1. INTRODUCTION Global programs are involved in addressing food and nutrition in the developing countries (WHO 2018). Improving nutrition is undoubtedly a challenging interdisciplinary proposition that involves availability and consumption of nutritious food. Covid-19 pandemic has further exposed the vulnerability of food systems in the low- and middle-income countries (LMICs). Green revolution was one milestone towards achieving food security when high yielding crop...
