Scottish child dead; controversy plagues E. coli investigation

The events that led to the death of a Scottish child who was among the 20 people that were infected with E. coli O157 (VTEC) began with the July 29 “precautionary recall” of two batches of Dunsyre Blue cheese suspected of containing the pathogen.

Recalled were the “C22” batch with best before dates of July 19 to July 26, and the “D14” batch with production dates of Aug. 7 to Aug. 15. The cheese was made with unpasteurized, raw milk.

Dbluecheese_406x250Selina Cairns, daughter of the founder of Errington Cheese and the company that recalled the Dunsyre Blue cheese for possible E. coli O157 contamination, has said all of the testing has turned out negative.

Cairns said all their company testing for almost six months previous, all Food Safety Authority testing, all customer and all farm testing—all were negative for E. coli O157. This included six samples taken from the “D14” batch.

“We don’t know why IMT (Incident Management Team) concluded that cheese batches C22 and D14 were responsible for illnesses as the wholesalers who supplied all the restaurants did not keep a record of which batches went to which customers; any of ten batches might have supplied these restaurants. We know from both our and the authority’s tests that D14 was negative for E. coli,” she said in a recent statement to media.

The IMT is led by Health Protection Scotland (HPS), and it has yet to either declare the outbreak over. It has not confirmed the Errington Cheese claims that all the testing has been negative for E. coli.

Scotland’s Food Standards Authority (FSA) in August blamed the outbreak on the popular Dunsyre Blue cheese. The HPS reported a majority of the 20 people infected with E. coli, including two from England, ate the cheese, but not everyone did.

The IMT has declined to provide Errington Cheese with copies of the outbreak report, food histories of those infected, including 11 who were hospitalized, and other supporting documents, nor has the official investigation named the locations where the suspect cheese was sold.

At an Aug. 17 meeting of the board of directors for the Scottish Food Standards Authority the chief executive officer reported that two batches of Dunsyre Blue produced by the Errington Cheese Company in Lanark had been associated with the outbreak.

“This particular type of blue cheese is made with unpasteurized cow’s milk,” Geoff Ogilvie, chief executive, said.

The failure to name the locations where the cheese was sold has come under fire by environmental health experts who say that vital information was kept from the public at a time when it might have helped people with symptoms seek medical care.

In her statement, Cairns said suspects she is the target of the investigation.

“At the moment they appear to be working to pin something on me; they seem to be taking no notice of an independent report carried out by a specialist microbiologist in the field or the large stack of of microbiological evidence showing E. coli O157 is NOT in the cheese,” she told media outlets.

“I think they need to make a statement saying, at the least, that they have found no trace of E. coli O157 in the recalled Dunsyre and are looking into other potential sources,” Cairns added. “At some point someone must look at this objectively and give scientific/microbiological evidence precedence over ‘circumstantial statistical analysis.’ ”

The IMT has told local media that it considers the Dunsyre Blue cheeses the most likely cause of the outbreak. Most of the illnesses occurred before the recall was announced, and all victims are suffering from the same strain of E coli O157, suggesting a common source.

The Food Standards Authority in Scotland is represented on the IMT along with numerous other agencies.

The name, age, and hometown of the child who died as a result of the outbreak has not yet been released.

In 1994, the Errington Cheese Co., led by its founder Humphrey Errington, went to court to contest food safety authorities who’d blamed the cheese-maker for what came to be known as the “Listeria Hysteria of 1989” after some people in Switzerland died. Errington was cleared and won the equivalent of almost $500,000 in court costs and compensation.

Errington Cheese today is run by Selina Cairns and her husband Andrew who are not sounding any more likely to accept findings they believe are in error. She contends HPS is “wrecking the reputation of dairly products in the whole country by making them appear unsafe.”

Canadian company recalls oysters because of Salmonella

Atlantic Shellfish Products Inc. is recalling oysters sent to retailers after Salmonella was detected during testing by the Canadian Food Inspection Agency.

logo Atlantic Shellfish Inc.As of the Monday posting of the recall notice, no illnesses had been reported in connection with the Atlantic Shellfish branded oysters. Officials were not sure if the implicated oysters had been distributed nationwide or just in the province of Quebec.

“Consumers should not consume and retailers, restaurants and institutions should not sell or use the recalled products described below. Check to see if you have recalled products in your home. Recalled products should be thrown out or returned to the store where they were purchased,” according to the recall notice.

“Food contaminated with Salmonella may not look or smell spoiled but can still make you sick.”

Young children, pregnant women, the elderly and people with weakened immune systems may contract serious and sometimes deadly infections from consuming food contaminated with Salmonella.

Healthy people may experience short-term symptoms such as fever, headache, vomiting, nausea, abdominal cramps and diarrhea. Long-term complications may include severe arthritis.

Project explores whether data-mining can help predict food recalls

A research project at the University of Washington to see whether analyzing food product reviews on Amazon.com might help to predict recalls is showing promise, and the team leader hopes it will have practical applications for illness outbreak investigations.

Project lead Elaine Nsoesie, Ph.D.., assistant professor of global health at the university’s Institute for Health Metrics and Evaluation, said that while the Unsafe Food Project is still in the “mission learning stage,” initial results are encouraging after a summer fellowship program recently ended.

“What we did this summer is get all the data we needed together from the FDA and try and match that data to the Amazon product reviews we were getting. It was more challenging than we expected,” she said.

“Then we created a database with all that data. The internship was only 10 weeks, so we didn’t have that much time. We tried to automate the process in the time we had.”

According to the program description, “The goal of this project is to use product reviews from Amazon.com to identify potentially unsafe food products. Foods that are mislabeled, contaminated, or spoiled get recalled through a time-consuming process that can leave consumers at risk of allergic reactions, injury, and illness for months. Our goal is to use reviews that consumers post online to predict whether a product will be recalled.”

Concern is growing over the lag time between when complaints about a food item surface and when a recall is announced. In some cases, it may take a year because illnesses must be reported and confirmed, food testing done, and a government investigation completed.

The project team mined the product reviews for specific terms such “sick,” “mold” and “vomit” and then tried to figure out which ones might help to predict subsequent food recalls.

Nsoesie said that the Amazon reviews turned out to be mostly positive, although a closer look occasionally indicated that something else might be going on.

“Some people are really sarcastic. They have a product that they really hate, but they will give it a five-star review, so when you read it, you see that it’s really a bad review. They might think they will get more attention with a good review than a bad one,” she said.

Even so, there were correlations that could be made, and the team had some success in linking subsequent recalls with the substance of the food product reviews.

“For some of them, we can possibly be able to predict a recall. For sensitivity of a model, it’s about 35 percent, so we need to work and improve on that,” Nsoesie said.

The project team also created an online tool for viewing recalled product reviews that shows reviews and ratings for a recalled product over time. The team noted that the reviews in the tool “provide some support for the idea that product reviews can be a fruitful data source for identifying unsafe foods.”

The tool has a pull-down menu with a variety of food products ranging from trail mixes and granola bars to chili, molasses, peanut butter, tea, spices and several others. After choosing one, it’s possible to see when and where the reviews are plotted along time and rating lines.

For a brand of Hungarian paprika, for example, the reviews posted from 2009-14 went from a high score of 5, with comments such as “Perfect!” and “I love it!,” to a low score of 1, with comments such as “Disgusting!” “Bugs in this product!,” and with a number of other comments landing in between.

Nsoesie said the next step for the project will be trying to get real information in real time. The team will seek cooperation from Amazon, Twitter, Yelp and perhaps others to get that accomplished since adequate data-gathering with better and faster technology is key.

“If someone has information about a tomato, you might not know what tomato they’re talking about. You need the product identification number (UPC) to track it back to the company and maybe back to where they got it,” she explained.

The Unsafe Food Project was one of four from the 2016 Data Science for Social Good summer fellowship at the UW’s eScience Institute in Seattle. In addition to Nsoesie, the team included Lead Data Scientist Valentina Staneva and Data Science Fellows Michael Munsell, Cynthia Vint, Kara Woo, and Kiren Verma.

Salmonella is an organism which can cause serious and sometimes fatal infections in young children, frail or elderly people, and others with weakened immune systems. Healthy persons infected with Salmonella often experience fever, diarrhea that is often bloody, nausea, vomiting and abdominal pain.

In rare circumstances, infection with Salmonella can result in the organism getting into the bloodstream and producing more severe illnesses such as endocarditis, arthritis and arterial infections, including infected aneurysms.

Salmonella outbreak linked to NC cheeses appears to be over

This is one of the photos from the Chapel Hill Creamery website that shows the company's production process.

This is one of the photos from the Chapel Hill Creamery website that shows the company’s production process.

It’s been more than a month since the last Salmonella case was confirmed in an outbreak traced to cheeses from a North Carolina company, suggesting the episode is over. Some of the implicated cheeses were made with unpasteurized, raw milk.

Chapel Hill Creamery recalled all of its cheese and ceased operations in late July. North Carolina’s health department reports that 98 state residents have been confirmed with the outbreak strain of Salmonella typhimurium. Sixteen of those 98 required hospitalization.

The North Carolina company recalled all of its cheeses, including this and other varieties made with unpasteurized, raw milk, after samples tested positive for the outbreak strain of Salmonella.

The North Carolina company recalled all of its cheeses, including this and other varieties made with unpasteurized, raw milk, after samples tested positive for the outbreak strain of Salmonella.

Onset dates for the North Carolina victims range from April 24 through July 30, said Cobey Culton, press assistant for the state’s Department of Health and Human Services. The victims ranged in age from infancy to more than 90 years old.

“Salmonella was isolated by the North Carolina Department of Agriculture and Consumer Services laboratory from a sample of finished cheese product collected on July 27,” Culton said. “The isolates recovered from the cheese sample matched the outbreak strain when tested at the State Laboratory of Public Health.”

Eight people from other states also became infected with the outbreak strain of Salmonella typhimurium, according to the Centers for Disease Control and Prevention.

“… These ill people all reported travel to North Carolina during their incubation period and were likely exposed to cheese from Chapel Hill Creamery at that time. We do not have any information to indicate that exposure to the recalled cheeses occurred in other states,” said CDC spokeswoman Kate Fowlie.

Chapel Hill Creamery distributed 15 varieties of cheeses in various combinations to retailers, restaurants and farmers markets in North Carolina, Georgia, South Carolina, Tennessee and Virginia. Co-founder Portia McKnight said Thursday that production has not yet resumed.

“We are working with the North Carolina Department of Agriculture and with other agricultural and food safety specialists to formulate and implement a recovery plan for our business,” McKnight said.
