Research -Mycotoxin Producing Moulds

NeoGen BlogAspergillus

With the harvest underway, it’s important to keep a watchful eye out for mycotoxin-producing molds. These species include Aspergillus flavus, which causes Aspergillus ear rot and produces the carcinogenic toxin aflatoxin, as well as species of Fusarium molds. These toxins can lead to production losses as grain may be rejected, as well as leading to illness in humans or animals that consume the toxin in significant quantities. Here’s a quick primer on some molds of concern and the toxins they produce. For more information and regulatory thresholds for toxins, please see Neogen’s Mycotoxin Handbook.

USA – One Dead from Salmonella Outbreak in Kentucky

Food Safety NewsSalm

Salmonella outbreak in Hopkins County, Kentucky, has killed one person and caused another seven confirmed illnesses.

The cause of the outbreak is still unknown, according to county health officials. Investigators have begun interviewing victims to see where or what they might have eaten in the days leading up to their illnesses.

UK – FSA Salmonella Outbreak investigation

FSASalmonella

An outbreak of an unusual type of salmonella infection, Salmonella Typhimurium, across England and Wales is being investigated by Public Health England, Public Health Wales, the FSA and local authority environmental health officers.

A total of 21 confirmed cases in Wales and 30 in England have been reported, with 9 cases known to have required hospitalisation. Other potential cases are being investigated in both countries.

The outbreak was first detected in Wales in August and centred mainly in North Wales (Conwy and Gwynedd), with additional clusters being investigated in England in the Thames Valley, Leeds, Cumbria and Stafford areas.

Cases are widely geographically distributed in patients aged 7 months to 87 years.

USA – Salmonella Outbreak in Iowa – Poultry or Eggs

Food Poisoning Bulletin

Mason City, Iowa, is the center of a Salmonella outbreak investigation that preceded a wider outbreak notice announced Friday by the Iowa Department of Public Health. Mason City is the seat of government for Cerro Gordo County, which leads all 19 Iowa counties in the number of illnesses associated with an outbreak of salmonellosis that may be linked to poultry or egg

USA – Warning – Vibrio in Warm Water Oysters

Food Safety News300px-Crassostrea_gigas_p1040848

The warmer coastal water temperature produced by summer weather creates ideal conditions for bacteria that can contaminate oysters, the Washington State Department of Health reminded the public over the Fourth of July weekend.

Vibrio vulnificus and Vibrio parahaemolyticus, two types of bacteria that grow in warm waters and can cause human illness, are known to be carried by oysters, especially in summer months.

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.

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.

Canada – Recall – Salmonella

CFIAEurofins

The Canadian Food Inspection Agency (CFIA) and Sunsprout Natural Foods are warning the public not to consume the Sunsprout and SproutsAlive brand alfalfa sprouts described below because they may be contaminated with Salmonella.

There have been no reported illnesses associated with the consumption of these products.

The manufacturer, Sunsprout Natural Foods, Brantford, Ontario, is voluntarily recalling the affected products from the marketplace.  The CFIA is monitoring the effectiveness of the recall.

Research in Germany – Listeria in Ready to Eat Foods

BfR

As part of an EU-wide baseline study, the BfR has investigated the presence of Listeria monocytogenes in smoked and gravad fish, soft and semi-soft cheese and also in heat-treated meat products. These foods are known to be potential carriers of elevated quantities of listeria. Overall, study results show that the prescribed microbiological criteria for Listeria monocytogenes are not always strictly adhered to in ready-to-eat foods. When limits are exceeded there is a risk of consumers contracting a Listeria monocytogenes infection. It is therefore imperative for food producers to ensure that the regulations are consistently met.

USA – CDC Vital Signs Website – Listeria Information

CDC Vital SignsE.coli O157

Many germs can be spread through food. Some, like Listeria, can be deadly. Listeria strikes hard at pregnant women and their newborns, older adults, and people with weakened immune systems. Listeria can cause miscarriage and meningitis. Most people found to have Listeria infection require hospital care and about 1 in 5 people with the infection die. Outbreak investigations tell us what foods make people sick and what needs to change to make food safer and save lives. We have made some progress against Listeria, which is the third leading cause of death from food poisoning. However, we can do more to protect people at higher risk for food poisoning and make food safer for everyone.

If you, or someone you make food for, are pregnant, 65 or older, or have a weakened immune system, you must be especially careful when selecting, preparing, and storing foods.

  • Know your risk of food poisoning.
  • Select, prepare, and store food safely.
  • Follow the safe food guidelines – Clean, Separate, Cook, Chill – at www.FoodSafety.gov
