Research – Safer Spinach – E.coli O157

Science Daily

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.

 

USA – Cheese – Listeria monocytogenes – Death and Miscarriage

Listeria BlogEurofins Food Testing UK

Les Freres cheese is distributed by Crave Brothers Farmstead Classics, a Wisconsin producer.  Crave Brothers cheese is sold at some of the Midwest restaurants, including Girl and the Goat in Chicago, Wild Rice in Bayfield, Wisconsin, and Butcher and the Boar in Minneapolis. In the Twin Cities, it is also sold at grocery stores such as Lunds, Byerly’s and Kowalski’s.  The products were distributed nationwide through retail and foodservice outlets as well as by mail orders.

According to the Minnesota Department of Health (MDH), two older adults in Minnesota got sick in early June after eating the cheese, and one later died.

The outbreak has sickened at least four others in three states, according to the Food and Drug Administration (FDA).  In addition to Minnesota, the other states involved are Illinois, Indiana and Ohio.  One of the cases was a pregnant woman who suffered a miscarriage.

All of those sickened were infected with the same strain of listeriosis, the FDA said.

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.

USA – Legionnaires Outbreak – Fitness Center

Food Poisoning BulletinLegionella_Plate_01

Three people reported contracting Legionnaires’ disease after visiting the 24 Hour Fitness on Ridgeway Road in East Memphis, Tennessee. The gym’s spa and pool are now closed pending an investigation by the Shelby County Health Department. Legionnaires’ disease, a form of pneumonia, is caused by breathing in water mist contaminated with Legionella bacteria.

Anyone who was at the 24 Hour Fitness on Ridgeway Road in the last 2 weeks should watch for symptoms of Legionnaires’ disease, including cough, fever, muscle aches, vomiting and diarrhea. This is a severe illness that is often fatal.
