UK- Scotland – Guidance for Scottish local authority officers on the production of cheese from unpasteurised milk


The Scottish Food Enforcement Liaison Committee (SFELC) has endorsed guidance produced by their Joint Specialist Cheese and Risky Foods Short-Life Working Group on the production of cheese from unpasteurised milk.

The guidance aims to control the microbiological risks in the production of artisan cheeses made from unpasteurised milk, specifically Shiga toxin-producing Escherichia coli(STEC). The guidance applies to all establishments producing cheese made from unpasteurised milk from cows, goats, sheep and buffalo.

Cheese made from unpasteurised milk has been linked to outbreaks of human illness and in particular, illness caused by STEC organisms including E. coli O157. The guidance has been developed in relation to the control of STEC and is intended for use during the inspection and enforcement of food safety controls applied by cheesemakers producing cheese made from unpasteurised milk.

The guidance reflects current scientific knowledge and understanding in relation to STEC and the production of cheese from unpasteurised milk. As scientific information and evidence on STEC evolves, the guidance will be reviewed. In addition, the guidance will complete a pilot implementation phase before a scheduled review.

The guidance is available to view at:

Alison Weiss, PhD, professor in the Department of Molecular Genetics, Biochemistry and Microbiology in UC College of Medicine, has been awarded a four-year grant of $1.6 million from the National Institute of Allergy and Infectious Diseases (NIAID) to study Shiga toxin producing Escherichia coli 0157:H7, also sometimes referred to as Hamburger E. coli.

Hamburger E. coli is the cause of foodborne illness and is an infection that often leads to bloody diarrhea and can result in kidney failure. It is mostly associated with eating undercooked, contaminated ground beef, and can be spread by person-to-person contact. In severe cases it can be fatal.

The infection was first discovered in hamburger meat, but it is carried asymptotically by many creatures so anything that has fecal matter from cattle can contaminate food, says Weiss. Vegetables and fruits can also carry E. coli if contaminated with animal fecal matter during field irrigation or as a result of harvesting or preparation of produce. Human hygiene practices can also spread E. coli.

Shiga toxin producing E. coli (STEC), including 0157:H7, are an important cause of diarrheal disease, causing about 265,000 illnesses in the United States annually.

USA – CDC Reports Romaine Lettuce Outbreak Over – E.coli

Food Safety Tech Eurofins Food Testing UK

Although FDA is continuing its investigation into the source of the E.coli outbreak involving romaine lettuce grown in California, the CDC has declared the outbreak over. Contaminated romaine that caused illnesses should no longer be available, FDA stated in an outbreak update. Consumers will not need to avoid romaine lettuce, and retailers and restaurants do not need to avoid selling or serving the product, according to the agency. Suppliers and distributors need not avoid shipping or selling any romaine that is on the market either.

As stated by CDC’s John Besser, Ph.D. last month at the Food Safety Consortium, “It’s been quite a year for outbreaks.” Here’s a not-so-fond look back at some of the noteworthy outbreaks and recalls of 2018.

Romaine Lettuce –E.coli O157:H7

Raw Beef Products – Salmonella

Shell Eggs – Salmonella

Pre-cut Melon – Salmonella

Vegetable Trays – Cyclospora

Salad Mix – Cyclospora

Raw Turkey – Salmonella

Honey Smacks Cereal – Salmonella

Duncan Hines Cake Mix – Salmonella

Johnston County Hams – Listeria monocytogenes

UK – Drinking raw milk – has led to a dangerous rise in food poisoning and killed TWO people, experts warn

The Daily Mail

Drinking raw milk has led to a dangerous rise in food poisoning, say experts   

  • A child fed raw milk in Wales died from a type of E. coli poisoning, while a man died of listeriosis after eating cheese made with raw milk 
  • Unlike pasteurised milk, which is heat-treated to kill bacteria, raw milk can harbour dangerous germs


USA – Wegmans Issues Voluntary Recall of Fresh Cauliflower Rice, Veggie/Cauliflower Rice Blend and Stir-Fry Mix with Cauliflower – E.coli O157


Wegmans Food Markets, Inc. has issued a voluntary recall of fresh Cauliflower Rice, Veggie Cauliflower Rice Blend and Stir-Fry Mix with Cauliflower, sold in the produce department between 12/7/18 and 12/18/18, because it may be contaminated with Escherichia coli O157:H7 bacteria (E. Coli O157:H7). E. coli O157:H7 causes a diarrheal illness often with bloody stools. Although most healthy adults can recover completely within a week, some people can develop a form of kidney failure called Hemolytic Uremic Syndrome (HUS). HUS is most likely to occur in young children and the elderly. The condition can lead to serious kidney damage and even death.

The recalled products (with use-by dates of 12/11/18 through 12/22/18) are as follows:

Wegmans Cauliflower Rice, 1 lb. pkg. UPC #25313500000
Wegmans Cauliflower Rice, 8 oz. pkg. UPC #25307200000
Wegmans Stir Fry Blend (with cauliflower), 1 lb. pkg. UPC #25335800000
Wegmans Veggie (cauliflower) Rice Blend (sold by the pound), UPC #253162000000

The recalled products were distributed to 98 Wegmans stores in N.Y., N.J., Pa., Md., Va. and Mass.

No illnesses have been reported to date.

The recall was initiated by Produce Packaging, Inc. based in Cleveland, OH, which supplies these products to Wegmans and notified Wegmans that the product may have been contaminated.
