Scientists sequence complete genome of E. coli Strain responsible for food poisoning

Researchers at the University of California, San Diego have produced the first complete genome sequencing of a strain of  E. coli  that is a common cause of outbreaks of food poisoning in the United States. Although the  E. coli  strain EDL933 was first isolated in the 1980s, it gained national attention in 1993 when it was linked to an outbreak of food poisoning from...

New research shows that Campylobacter can cause disease in chickens

Contrary to popular belief, the foodborne pathogen  Campylobacter jejuni  is not a harmless commensal in chickens but can cause disease in some breeds of poultry according to research published in mBio®, the online open-access journal of the American Society for Microbiology. "The main implication is that Campylobacter is not always harmless to chickens. This...

What fuels Salmonella’s invasion strategy?

Certain strains of Salmonella bacteria such as  Salmonella Typhimurium (S. Typhimurium)  are among of the most common causes of food-borne gastroenteritis. Other strains of  Salmonella  such as  S. Typhi  are responsible for typhoid fever, which causes 200,000 deaths around the world each year. Ensuring food is clear of contamination, and water is...

Benign bacterium shows promise in blocking Salmonella from colonising raw tomatoes

Scientists from the U.S. Food and Drug Administration (FDA) have identified a benign bacterium that shows promise in blocking  Salmonella  from colonising raw tomatoes. Their research is published ahead of print in the journal Applied and Environmental Microbiology. When applied to  Salmonella -contaminated tomato plants in a field study, the bacterium, known...

InstantLabs and the University of Guelph to develop seafood identification test kits

InstantLabs has entered into an agreement with the University of Guelph to co-develop a portfolio of DNA-based seafood species identification tests to combat marketplace seafood fraud by providing rapid, definitive proof that seafood is correctly labeled. InstantLabs plans to launch the kits within four months. Recent studies have shown that fraud could be occurring in 25 to 70 percent...

New EU project aims to develop new animal doping test to protect food chain

Scientists at Queen’s University Belfast and the Irish Equine Centre are to develop a new way to test for illegal drugs used in horses and cattle. It will be the first animal doping test to work by detecting and monitoring the known biological effects of a banned substance, rather than the presence of the substance itself. It also has the potential to revolutionise animal drug testing...

New biosensor makes salmonella detection faster and easier

Faster, more accurate and with the ability to multi-task; a new biosensor developed by scientists at Rice University looks set to take salmonella detection to a new level. Standard food industry tests each have their limitations. Culturing colonies of salmonella can take days, DNA-based tests are laborious to set up and antibodies are unstable and can break down easily.    ...

Poultry probiotic’s coat provides clues to ability to battle bugs

Researchers at the BBSRC strategically-funded Institute of Food Research have characterised the coat of a potential poultry probiotic, giving the first clues of how it may be used to exclude pathogenic bacteria from chickens. Lactobacillus johnsonii has previously been shown to exclude Clostridium perfringens from the guts of poultry, opening the door to it being developed as a way...

FSA outlines refreshed strategy against campylobacter

The Food Standards Agency (FSA) has outlined a “refreshed” strategy to reduce the number of people affected by the most common cause of food poisoning in the UK, campylobacter. Up to 65% of chicken on sale in the UK is contaminated with campylobacter, and poultry accounts for a significant proportion of the 460,000 cases of food poisoning attributed to campylobacter in the UK each...

Researchers track antibiotic-resistant strains of Salmonella from farm to fork

Continuing research on  Salmonella  may enable researchers to identify and track strains of antibiotic resistant bacteria as they evolve and spread, according to researchers in Penn State's College of Agricultural Sciences. Tracing the transmission of individual strains from agricultural environments to humans through the food system is difficult because of the rapid evolution...

Poultry drug increases levels of toxic arsenic in chicken meat

Chickens likely raised with arsenic-based drugs result in chicken meat that has higher levels of inorganic arsenic, a known carcinogen, according to a new study led by researchers at the Johns Hopkins Center for a Livable Future  at the Bloomberg School of Public Health. This is the first study to show concentrations of specific forms of arsenic (e.g. inorganic arsenic versus...

The importance of Aquaculture in the 21st Century

A new report published by the FAO stipulates that aquaculture is the fastest-growing animal producing sector, accounting for nearly half (46%) of the world's food fish consumption, forecasted to surpass 50% by the end of this year. One of the key findings of the report, entitled World Aquaculture 2010, was that between 2000 and 2008, global fish production grew from 32.4...
