European Epdiemiological Report into the Salmonella Stanley Outbreak 2012

ECDCecdclogo

In July 2012, the European Centre for Disease Prevention and Control (ECDC) initiated a Europe-wide investigation on a Salmonella Stanley outbreak, together with the affected Member States, the European Food Safety Authority (EFSA) and the European Reference Laboratory for Salmonella (EURL Salmonella). Cases were associated with strains showing an indistinguishable PFGE pattern not previously reported in Europe.

Between July and September 2012, ECDC encouraged European Union (EU) and other European Economic Area (EEA) Member States to perform Xbal-PFGE typing on all S. Stanley human isolates. The image profile of the outbreak strain was shared with all EU countries. ECDC collected and analysed molecular typing data on S. Stanley from EU/EEA Member States to explore potential sources of infection within the food production chain in this multi-country outbreak.

Bacteria and fungi: are they friends of foes? In the case of Pseudomonas aeruginosa and Candida albicans, they’re definitely foes. A study in mBio this week reveals that P. aeruginosa puts the kibosh on C. albicans’ growth by altering the fungus’ respiratory activity.

 

Research – Killing Pathogens on Seeds

Science Direct

Farmers treat seeds chemically in order to rid them of pest infestation. Now researchers have developed a method that kills pathogens without harming the environment. Pioneering seed suppliers are already implementing the procedure commercially.

The scientists of the Fraunhofer Institute for Electron Beam and Plasma Technology FEP in Dresden, Germany have developed an environmentally friendly method for removing germs from seeds. They treat the seeds with electrons, which within milliseconds destroy the DNA of the harmful organisms. Due to a special device setup, the elementary particles only act on the surface and in seed coat. The embryo in the interior of the seed is not affected so that the ability of the seeds to germinate is not impaired.

The scientists from the FEP are confident that, in the long term, the treatment with electrons will prove to be a success story. There is some support for this: Starting in 2015, farmers must prove that they are trying to reduce their CO2 footprint and lower the use of chemical pesticides. “With our unit, we are able to contribute significantly to this,” says Rögner. Should the treatment with electrons gain greater acceptance, the scientists from FEP could license their process to plant construction companies.

The scientists are currently promoting their activities abroad. The FEP is endeavoring to introduce the electron treatment process into the Chinese and Indian markets. “Due to the large amounts of seed produced, we see good opportunities there,” says Rögner.

Science Direct

Abstract

To understand the general trends and status of China’s food safety, we analyzed 2387 individual incidents of acute foodborne illnesses that had been reported by medical professionals in published journal papers during the last decade. As a result, 99,487 illnesses and 380 deaths were found in these 2387 incidents. In our analysis, we tried to understand the risks of acute foodborne illnesses and deaths corresponding to food pathogens, food location and settings, implicated food vehicles, sources of contamination and human causes. Based on our analysis, we made recommendations for risk communication, risk management and future research in regard to foodborne illnesses in China.

Highlights

► We analyze China’s food safety problem in the case of acute foodborne illness. ► Data were extracted from detailed reports on 2387 incidents of foodborne illness. ► Risk factors are discussed from multiple perspectives. ► Recommendation for policies and strategies towards food safety are provided. ► This is so far the most comprehensive analysis of acute foodborne illness in China.

UK – East Midlands Free Listeria Seminar for SME’s

ReadyMealsInfo

East Midlands food businesses that make, distribute and sell chilled, ready-to-eat products are to be given help and advice to help them keep their products safe from Listeria.

According to data from the Food Standards Agency (FSA) serious cases of laboratory-confirmed Listeria infection in the UK almost doubled between 2000 and 2009. In 2010 numbers decreased but were still higher than during the 1990s.
The Food and Drink iNet, which is run by trade organisation The Food and Drink Forum, is funding a six-month collaborative research and development project at The University of Nottingham working with the food hygiene specialists Diversey, to turn the spotlight on the issue.

As part of the project, a seminar is being run to give small and medium-sized businesses in the chilled food sector, guidance and advice about how to manage the risk of Listeria.  The seminar will be held in the Plant Sciences Building at the University’s Sutton Bonington campus between 4 pm and 6.45 pm on Wednesday February 13.

The Food and Drink iNet, which is part-funded by the European Regional Development Fund (ERDF), is managed by a consortium, led by the Food and Drink Forum and including Nottingham Trent University, the University of Lincoln, and The University of Nottingham. It is based at Southglade Food Park, Nottingham, with advisors covering the East Midlands region to offer a range of support to small and medium-sized enterprises that work in the sector.

To book places at the seminar email iNet advisor Jo Murphy at jo.murphy@foodanddrink-inet.org.uk and for more information visit www.foodanddrink-inet.org.uk

 

 

UK -FSA – Results of Industry Testing

FSAfood_standards_agency_logo

The Food Standards Agency (FSA) has agreed with the food industry to publish the results of industry testing of meat products, to provide a clearer picture of standards in the food chain. The results will also be made publicly available.

The decision was taken at a meeting to address how testing can maintain consumer confidence in the accuracy of food labelling, attended by Food and Farming Minister David Heath, representatives of the FSA, and major food businesses and suppliers.

Catherine Brown, Chief Executive of the FSA, said: ‘I am pleased that we have been able to agree a way forward to maintain consumer confidence in the food that people eat. We need to move swiftly to get this work under way to reassure consumers.’

Research – Super Feezing Campylobacter to Death !

news.scotsman.comCampylobacter

FOOD safety experts plan to “superfreeze” chickens to halt the rise of campylobacter  food poisoning. The Food Standards Agency is currently looking into a procedure which involves exposing the surface of slaughtered chickens to extreme cold, known as rapid surface chilling.

The radical process is currently being considered to help curb the rampant levels of  the food poisoning bacteria commonly found in uncooked poultry products.

Around two-thirds of fresh, raw chicken sold by retailers is believed to be contaminated with campylobacter, which can cause sever stomach upsets.

The FSA aims to reduce the proportion of birds in the highest category of contamination at UK poultry houses from 27 per cent to 10 per cent by 2015.

Dr Jacqui McElhiney, policy adviser on food-borne disease at the FSA in Scotland, said: “This process acts to temporarily cool only the very outer surface of the chicken carcass without freezing the meat itself. It involves exposing the surface of poultry carcasses to very low temperatures for a very short time, which reduces the numbers of campylobacter bacteria on the surface, as they are sensitive to an extreme cold shock treatment of this type.”

Research – Campylobacter Movement to Search for Food

Science DailyCampylobacter

Researchers at the Institute of Food Research on the Norwich Research Park have uncovered how the food-borne bacterial pathogen Campylobacter jejuni can change its swimming behaviour to find a location with more food.

Using a newly developed assay, the researchers found that Campylobacter balances the directions given by two different systems to either seek out more nutritious locations, or to find places where respiration is most efficient. Genetic tools were used to show that the system controlling swimming towards food overrides the other system, suggesting that the “need to feed” is the foremost concern for Campylobacter.

Research – Campylobacter in Chickens

HACCP EuropaimagesCAJOQ0KC

Poultry producers can reduce bacterial cross-contamination in poultry cages by treating the cages with forced air that’s been heated to 50 degrees Celsius.

While being transported in coops on trucks, poultry that have bacteria such as Campylobacter can contaminate, through their feces, other poultry that are free of pathogens. Those disease-causing bacteria can then be passed on to the next group of birds during the next trip, and so forth, unless the cycle is broken.

Campylobacter is a food-borne pathogen that can be present in raw or undercooked poultry. Since the bacteria are commonly found in the digestive tracts of poultry, they’re readily deposited onto coops and trucks when contaminated animals are transported to processing plants.

The researchers tested the use of hot flowing air to speed the process of drying soiled or washed cages to lower or eliminate detectable Campylobacter on cage flooring.

When the hot flowing air was applied to fecally soiled transport cage flooring samples for 15 minutes after a water-spray wash treatment, Campylobacter levels declined to an undetectable level. Static heat at similar temperatures was not nearly as effective, and unheated flowing air was moderately effective, but less so than hot flowing air.

Research – Listeria Antibiotic Resistance in Burgers

Science Direct

Malaysian researchers have revealed the presence of multidrug-resistant strains of Listeria monocytogenes in frozen burger patties taken from supermarkets and other retail shops in Malaysia. The research was published in Pertanika Journal of Tropical Agricultural Science.

A recent publication by W.C. Wong and colleagues in the Pertanika Journal of Tropical Agricultural Science revealed the presence of multidrug-resistant strains of Listeria monocytogenes in frozen burger patties taken from supermarkets and other retail shops in Malaysia.

The results also suggested that the overall incidence of antibiotic resistance in L. monocytogenes is relatively low, and that most of the bacterial strains isolated from food are susceptible to antibiotics commonly used in veterinary and human therapy.
