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.

USA – Cyclospora Outbreak

Livewell Nebraska220px-Cyclospora_cayetanensis_stained

Fourteen more cases of cyclospora infection were reported Friday to Nebraska and Iowa public health officials, adding to the 12 that had come in over the past several days.

Officials still are trying to determine the source of the Cyclospora cayetanensis parasite, which causes an intestinal infection called cyclosporiasis. They’re telling physicians to be aware of the illness and to test specifically for the parasite

The new Nebraska cases appear to be from the eastern part of the state, as did the earlier cases, according to a spokeswoman for the Nebraska Department of Health and Human Services. Most of the new Iowa cases were from central and eastern Iowa, said Dr. Patricia Quinlisk, medical director of the Iowa Department of Public Health. One case, she said, involved an Iowan who was tested in Omaha.

Cyclospora is spread by people ingesting food or water that is contaminated with feces. People living or traveling in tropical or subtropical regions of the world may be at increased risk for infection because cyclosporiasis is found in those areas. Foodborne outbreaks of the illness in the U.S. have been linked to various types of imported fresh produce, such as raspberries, basil, snow peas and mesclun lettuce.

People need to wash all fresh produce, health officials said.

The symptoms of cyclospora infection can last for weeks in otherwise healthy people. They include fatigue, lack of appetite, nausea, abdominal cramping and a low-grade fever.

People with compromised immune symptoms will have more severe and longer-lasting symptoms

What is cyclospora?

Cyclospora cayetanensis is a parasite made of one cell, too small to be seen without a microscope. This parasite causes an intestinal infection called cyclosporiasis.

How is cyclospora spread?

Cyclospora is spread by people ingesting something, such as food or water, that is contaminated with feces. Cyclospora needs days to weeks after being passed in a bowel movement to become infectious for another person. Therefore, it is unlikely that cyclospora is passed directly from one person to another.

Who is at risk for cyclospora infection?

People living or traveling in tropical or subtropical regions of the world may be at increased risk for infection because cyclosporiasis is found in some countries in the zones. In the United States, food-borne outbreaks of cyclosporiasis have been linked to various types of imported fresh produce.

What should I do if I think I might be infected with cyclospora?

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.
