Research – New Zealand Controlling Campylobacter in Poultry Flocks

Ingenta ConnectEurofins Food Testing

An analysis of the cost-effectiveness of interventions to control Campylobacter in the New Zealand poultry supply examined a series of interventions. Effectiveness was evaluated in terms of reduced health burden measured by disability-adjusted life years (DALYs). Costs of implementation were estimated from the value of cost elements, determined by discussions with industry. Benefits were estimated by changing the inputs to a poultry food chain quantitative risk model. Proportional reductions in the number of predicted Campylobacter infections were converted into reductions in the burden of disease measured in DALYs. Cost-effectiveness ratios were calculated for each intervention, as cost per DALY reduction and the ratios compared. The results suggest that the most cost-effective interventions (lowest ratios) are at the primary processing stage. Potential phage-based controls in broiler houses were also highly cost-effective. This study is limited by the ability to quantify costs of implementation and assumptions required to estimate health benefits, but it supports the implementation of interventions at the primary processing stage as providing the greatest quantum of benefit and lowest cost-effectiveness ratios.

Research – Safer Spinach – E.coli O157

Science Dailyspinach

University of Illinois scientists have found a way to boost current  industry capabilities when it comes to reducing the number of E. coli 0157:H7 cells that may live undetected on spinach leaves.

“By  combining continuous ultrasound treatment with chlorine washing, we can  reduce the total number of foodborne pathogenic bacteria by over 99.99  percent,” said Hao Feng, a U of I professor of food science and human  nutrition.

Guidelines for the public health management of gastroenteritis outbreaks due to
norovirus or suspected viral agents in Australia

Better Health Channel

Gastroenteritis (gastro) is an illness triggered by the infection and inflammation of the digestive system. Symptoms include abdominal cramps, diarrhoea and vomiting. Some of the causes include viruses, bacteria, bacterial toxins, parasites, particular chemicals and some drugs. The main complication of gastroenteritis is dehydration, but this can be prevented if the fluid lost in vomit and diarrhoea is replaced.

Research – Olive Powder Combatting E.coli in Hamburgers

FeedStuffs FoodLink

The potential of olive powder to keep foods safe to eat is getting a fresh look from Albany chemist Mendel Friedman and colleagues at the University of Arizona-Tucson.

An olive processing co-product, olive powder was one of about two dozen plant extracts, spices, and herbs that the team evaluated for their potential to combat Escherichia coli O157:H7 and to retard formation of heterocyclic amines during cooking of hamburger patties.

E. coli O157:H7 is a leading cause of food sickness in the U.S. and is blamed for more than 73,000 cases of illness annually. In recent years, many E. coli outbreaks have been traced back to ground beef and have led to the introduction of stringent new food safety rules designed to reduce the occurrence of this microbe, and six of its relatives, in meats, poultry, and other foods.

The ability of olive extracts to kill foodborne pathogens has been reported in earlier studies conducted at Albany, Tucson, and elsewhere. However, the E. coli and amines study, reported in a 2012 issue of the Journal of Agricultural and Food Chemistry, may be the first to show olive powder’s performance in concurrently suppressing three targets of concern — two major amines and a pervasive E. coli.

University of Illinois scientists have found a way to boost current  industry capabilities when it comes to reducing the number of E. coli 0157:H7 cells that may live undetected on spinach leaves.

“By  combining continuous ultrasound treatment with chlorine washing, we can  reduce the total number of foodborne pathogenic bacteria by over 99.99  percent,” said Hao Feng, a U of I professor of food science and human  nutrition.

According  to Feng, the USDA is looking for proposed technologies that can achieve  a 4 to 6 log reduction in pathogen cells (a 6 log reduction would  achieve a million-fold reduction in pathogenic bacteria). The food  processing industry can now achieve a 1 log or tenfold reduction. In  comparison, the U of I technique yields a 4 log reduction.

 

Europe – Report into Listeria Prevalence in RTE Foods

EFSAefsa

The first part of EFSA’s analysis of an EU-wide baseline survey on Listeria monocytogenes published today provides valuable insights  into the presence of this bacteria in certain ready-to-eat foods (fish, cold  meats and soft cheeses[1]). The proportion of food samples exceeding the legal  food safety limit was low. However, given the popularity of these foods and the  severe implications that Listeria infections (listeriosis) can have on human  health, overall vigilance regarding the possible presence of the bacteria in  food is warranted. To prevent listeriosis,  EU legislation lays down specific rules for  food business operators including the need to follow  good manufacturing practices, appropriate food  hygiene programmes, and effective temperature control throughout the food chain.  Experts highlighted the importance of these  measures as well as proper storage of these foods in the home, keeping  refrigerator temperatures low.

UK – FSA – Curry Leaves Reminder – Salmonella

FSAfood_standards_agency_logo

The Food Standards Agency is reminding those who eat or use fresh curry leaves in their dishes, to ensure that the leaves are washed thoroughly before use. Cooking provides further assurance that these leaves are safe to eat.

The use of uncooked fresh curry leaves, which were contaminated with several different bacteria including salmonella, was the cause of a food poisoning outbreak which affected more than 400 people at the Street Spice festival in Newcastle. Further information on the recent Newcastle City Council and Public Health England investigation into this incident can be found on the PHE website. See ‘External sites’ links.

UK – FSA Annual Food Incidents Report

FSA food_standards_agency_logo

The Food Standards Agency has today published its latest Annual Report of Food Incidents. The report highlights the wide range of incidents managed by the Food Standards Agency during 2012.

Last year, a total of 1,604 food and environmental contamination incidents in the UK were reported to and investigated by the FSA. This figure was 110 down on 2011 but higher than in many previous years. The three largest contributors to these incidents were microbiological contamination (20%), environmental contamination (15%) and natural chemical contamination (13%).

One of the valuable roles played by the report is providing insight into why certain types of incident have increased. For example, FSA investigations show a recent rise in a certain type of salmonella was mostly the result of paan leaves imported from Bangladesh. Similarly, the number of allergen-related incidents appears to have risen by more than half since 2010. Statistics suggest, however, that legislative changes relating to gluten may have been a major contributory factor.

The report also shows a rise in the number of whistleblowers who contacted the FSA during the year. A total of 81 cases originated from whistleblowers during 2012 – up from 54 the previous year.

Catherine Brown, Chief Executive of the Food Standards Agency, said: ‘We hope that this annual report encourages food businesses and consumers to notify us promptly of incidents and of any other potentially-useful intelligence they have. This will enable us to act swiftly to protect the public and the food industry and, in so doing, increase public confidence in food safety.’

The data released today does not include the incidents of horsemeat contamination that came to light in the first half of 2013, as these occurred outside of the scope of the report. All incidents notified to the FSA are reviewed, and in the case of horsemeat the FSA has commissioned an additional independent external review of how it responded. This is due to report shortly.

Catherine Brown said: ‘Although the horsemeat incident occurred outside the scope of this report, I would like to highlight the resolve with which the FSA responded. Working closely with other Government departments and the food industry, the Agency ensured that 6,000 tests of frozen products were carried out within three weeks – far more than any other EU member state. The UK was also the first country to submit a dossier to Europol and the first country to make arrests.

‘By responding so quickly, we were able to reassure the public that more than 99% of the tests undertaken in the UK contained no horse DNA at the level of 1% or above, and that there was no threat to public health.’
