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 – Microbiological Quality of Fresh-Cut Carrots and Process Waters

Ingenta ConnectSalmonella

Fresh vegetables may be contaminated by pathogens in different ways after harvest. Pathogenic microorganisms associated with fresh vegetables can cause severe outbreaks of foodborne disease. We discuss here the results of microbiological analysis of carrot samples, as well as of washing, processing, and wastewater samples. Washed, unpeeled carrots generally contained the highest aerobic plate counts (mean, 5.5 log CFU/g). Escherichia coli was not detected in any carrot or water sample examined. The amounts of coliform bacteria and enterobacteria were higher in carrot samples taken from the first steps in the processing line than in samples taken in later phases of the process. Yersinia pseudotuberculosis was not detected in any of the samples by the cultivation method; however, nonpathogenic Yersinia enterocolitica was detected from most carrot samples and almost all washing water and wastewater samples but only from 2 of 10 process water samples. Using a more-sensitive real-time PCR method, pathogenic Y. enterocolitica was found from several carrot samples, and when these positive samples were cultivated, no pathogenic Y. enterocolitica strains were detected.

USA – Shigella Outbreak Traced to Lake Water

Food Safety News220px-Shigella_stool

The 750 feet of developed beachfront at Rhode Island’s Spring Lake is scattered with volleyball courts, paddle boats, canoes, food concessions and an entertainment arcade.  That beach, located in Burrillville, did not host the crowd of 2,000 that usually attend its Fourth of July festivities. Instead, days earlier, 92 people who entered the water at Spring Lake left sickened by Shigella bacteria.

The Shigella outbreak sent 16 people to area hospitals and by Sunday forced state officials to close the lake to swimmers.  Shigella causes gastrointestinal symptoms, but the illnesses are usually not severe.

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.

USA Research – Listeriosis in the Elderly

Food Poisoning Bulletin

Listeria monocytogenes isn’t one of the most common causes of food poisoning, but it is one of the most deadly. Some segments of the population are at special risk. About 90 percent of people who develop Listeria infections fall into three groups, pregnant women, seniors and those with weakened immune systems.

Paul’s story is featured on the Centers for Disease Control and Prevention’s (CDC’S) website. Paul was a World War II veteran who had received two Purple Hearts. At 92, he was active and in good health when he got listeriosis from eating tainted cantaloupe in September 2011. He died three months later, leaving behind his wife Rosellen of 68 years, five children, nine grandchildren, and 10 great grandchildren.

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.

USA – Listeria Outbreak in Cheese Updates

Food Poisoning Bulletin

The Minnesota Department of Health has released information about the multistate Listeria outbreak linked to recalled Crave Brothers soft cheeses. Two people in Minnesota have been sickened in this outbreak. Both were older adults who became ill in early June; one of them has died.

Food Poisoning Bulletin

Two Illinois restaurants served the Crave Brothers soft French cheeses that have been linked to a multistate Listeria outbreak. Girl & The Goat in Chicago, and the Hilton Hotel in Chicago sold the recalled cheese. Anyone who ate Les Frères, Petit Frère, or Petit Frère with Truffles at those restaurants may be at risk for developing listeriosis, a serious disease.

Food Poisoning Bulletin

To date, two Minnesota residents have contracted Listeria food poisoning (listeriosis) after eating Les Freres cheese produced by Crave Brothers Farmstead Cheese Company. One of Minnesota victim died. Prompted by this outbreak, Crave Brothers issued a recall of some of its cheese products, including Les Freres (LF225 2/2.5#), Petit Frère (PF88 8/8 oz) and Petit Frère with Truffles (PF88T 8/8 oz), all with a make date of 7-1-13 or earlier.

Food Poisoning Bulletin

A premier Minnesota restaurant, Butcher & The Boar, is the only restaurant in the state named by Crave Brothers Farmstead Cheese Company as a recipient of soft cheese associated with a deadly outbreak of listeriosis. Whole Foods Markets, Lunds, Byerlys, Rainbow, Kowalski’s and other grocery retailers also sold the cheese, as did restaurants in Wisconsin and Illinois. The recalled gourmet cheese has been associated with a Listeria death in Minnesota, a second Minnesota illness and individual cases of listeriosis in Illinois, Indiana and Ohio. All five people were hospitalized and one infection in a pregnant woman resulted in miscarriage.

Food Posioning Bulletin

The Centers for Disease Control and Prevention has joined the investigation by the Minnesota Department of Health into the Listeria outbreak linked to Crave Brothers Farmstead Cheeses. The company recalled three types of its cheeses on July 3, 2013 after an outbreak was announced. At least five people have been sickened in four states; one person in Minnesota has died and a woman has suffered a miscarriage.
