USA – Outbreak Investigation of Listeria monocytogenes: Ice Cream (July 2022)

Outbreak Investigation of Listeria Monocytogenes in Florida-Based Big Olaf Ice Cream (July 2022) - CDC Case Count Map as of July 11, 2022

FDA

The FDA, along with CDC, is assisting the Florida Department of Health (FL DOH) and Florida Department of Agriculture & Consumer Services (FDACS) in investigating an outbreak of Listeria monocytogenes infections linked to ice cream supplied by Big Olaf Creamery of Sarasota, Florida.

Based on epidemiological information collected by CDC and the FL DOH, Big Olaf ice cream products are a likely source of illness in this outbreak. A total of 23 people infected with the outbreak strain of Listeria monocytogenes have been reported from 10 states. Of the 18 people interviewed, all (100%) reported eating ice cream. Among 18 people who remembered details about the type of ice cream they ate, 10 reported eating Big Olaf Creamery brand ice cream or eating ice cream at locations that might have been supplied by Big Olaf Creamery. Twelve sick people are residents of Florida and nine reported traveling to Florida before getting sick.

FDA is concerned that retailers may still be selling Big Olaf ice cream products. Retailers should not sell or serve Big Olaf ice cream products and should throw them away. Consumers who may still have these products in their freezers should not eat or serve any Big Olaf ice cream products and should also throw the product away.

This is an ongoing investigation, and the firm has initiated a voluntary recall of its ice cream products. The FDA is continuing to work with the FL DOH and FDACS to investigate and will update this advisory should additional consumer safety information become available.

Recommendation

Consumers, restaurants, and retailers should not eat, sell, or serve any Big Olaf ice cream products and should throw the product away, regardless of the “Best By” or expiration date.

Call your healthcare provider right away if you have these symptoms after eating Big Olaf ice cream products:

  • Pregnant people typically experience only fever, fatigue, and muscle aches. However, Listeria infection during pregnancy can lead to miscarriage, stillbirth, premature delivery, or life-threatening infection of the newborn.
  • People who are not pregnant may experience headache, stiff neck, confusion, loss of balance, and convulsions, in addition to fever and muscle aches.

Consumers, restaurants, and retailers who purchased or received any Big Olaf ice cream products should throw the products away, follow FDA’s safe handling and cleaning advice and use extra vigilance in cleaning and sanitizing any surfaces and containers that may have come in contact with these products to reduce the risk of cross-contamination. Listeria can survive in refrigerated temperatures and can easily spread to other foods and surfaces.

USA – Listeria Outbreak Connected to Big Olaf Creamery Allegedly Causes Death of One Woman

Food Poisoning News

A recent outbreak of Listeria infections is believed to be linked to an ice cream producer in Sarasota, Florida, called Big Olaf Creamery. The U.S. Center for Disease Control and Prevention (CDC) reports that there have been 23 people affected by the outbreak with 22 of these people seeking hospitalization due to the severity of their symptoms. One woman, Mary Billman, has passed away, allegedly due to the consumption of Big Olaf ice cream. Ms. Billman’s estate is pursuing legal action in response to her death.

Research – Collective food poisoning (TIAC) ​​with E. coli O157 producing Shiga toxins, associated with the consumption of raw cucumbers

Sante Publique

On September 9, 2021, the Regional Health Agency (ARS) of Hauts-de-France was informed of a suspicion of collective food poisoning (TIAC) ​​affecting half-board students, educated in several schools in a municipality. of the Lille metropolis. 

On September 13, 2021, two cases of haemolytic and uremic syndrome (HUS) were diagnosed in two hospitalized children attending school in this town. Public Health France Hauts-de-France was asked by the Hauts-de-France ARS to provide support for the investigations and management of this TIAC. A total of 35 cases of gastroenteritis, with bloody diarrhea and fever (>38°C) in half of the cases, were identified. Ten cases were hospitalized and two children developed HUS. 

The cases identified were half-board students in four school groups (29 cases), a parent of a student and elderly people benefiting from the municipality’s home meal delivery service (5 cases). The case canteens were all supplied by the central municipal kitchen. 

The shape of the epidemic curve was in favour of a common and point source of contamination during meals on September 2 or 3, 2021. The case-control survey, carried out in schools, concluded that only the consumption of cucumbers in salad, served with the meal on September 2, was statistically and significantly associated with the occurrence of the disease.

A strain of E. highly pathogenic Shiga toxin-producing (STEC) O157 coli was isolated from the stool cultures of eight cases, including the two children who developed HUS and in the offending cucumber salad. Genomic analysis of the strains confirmed the genetic clustering of clinical and food strains that belonged to the same genomic cluster. The veterinary investigation revealed that a failure in the decontamination process, associated with incomplete peeling of the contaminated cucumbers, contributed to the occurrence of this TIAC. 

The cucumbers in question came from Belgium and the Belgian health authorities were informed via the dedicated European alert circuits. No other episodes of clusters of STEC infection related to this TIAC have been reported to the ARS over the period while cucumbers from the same batch had been widely distributed in communities and commercial catering services in the Hauts-de-France region. The food vehicle, incriminated in this TIAC, is part of the plants at risk because of its raw mode of consumption. It is important to remind vulnerable populations and collective catering services that preventing the risk of STEC infection, linked to the consumption of raw vegetables, requires washing, disinfection and peeling.

Canada – Mystery Cyclospora Outbreak spreads to Canada

Food Poison Journal

Public Heath Canada is working with its public health and food safety partners to identify possible ways non-travel related Cyclospora infections are occurring in Canada.

As of June 30, a total of 84 cases of Cyclospora infections were reported in the following provinces: British Columbia (1), Ontario (75), and Quebec (8). 4 individuals have been hospitalized and no deaths have been reported. To date, there is no recall or Public Health Notice, the investigation is ongoing.

In case you are experiencing Cyclosporiasis symptoms such as watery diarrhea (most common), cramping, bloating, increased gas, nausea, fatigue, and possibly vomiting and low-grade fever, it is important to report it. It can help to detect & resolve outbreaks early and prevent others from being harmed, and it enables better surveillance. If symptoms persist, seek medical care.

Research – Simulation and identification of foodborne outbreaks in a large supermarket consumer purchase dataset

Nature.com

Foodborne outbreaks represent a significant public health burden. Outbreak investigations are often challenging and time-consuming, and most outbreak vehicles remain unidentified. The development of alternative investigative strategies is therefore needed. Automated analysis of Consumer Purchase Data (CPD) gathered by retailers represents one such alternative strategy. CPD-aided investigations do not require trawling questionnaires to create a hypothesis and can provide analytical measures of association by direct data analysis. Here, we used anonymized CPD from 920,384 customers enrolled in Norway’s largest supermarket loyalty program to simulate foodborne outbreaks across a range of different parameters and scenarios. We then applied a logistic regression model to calculate an odds ratio for each of the different possible food vehicles. By this method, we were able to identify outbreak vehicles with a 90% accuracy within a median of 6 recorded case-patients. The outbreak vehicle identification rate declined significantly when using data from only one of two retailers involved in a simulated outbreak. Performance was also reduced in simulations that restricted analysis from product ID to the product group levels accessible by trawling questionnaires. Our results show that—assuming agreements are in place with major retailers—CPD collection and analysis can solve foodborne outbreaks originating from supermarkets both more rapidly and accurately than than questionnaire-based methods and might provide a significant enhancement to current outbreak investigation methods.

Research – Source of 7-year Listeria outbreak found in Germany

Food Safety News

German officials believe they have solved a seven-year Listeria outbreak that included the death of one man.

Using next generation sequencing (NGS) methods, the Bavarian State Office for Health and Food Safety (LGL) helped identify a likely connection between Listeria infections in Lower Bavaria and in the district of Altötting since 2015 and a food company.

The company was not named by authorities but they described it as a small businesses in the district of Passau that had various customers in the region. Local media reported it was a produce company that supplied canteens and care homes but not retailers.

Alongside the results from the NGS analysis, there are indications of an epidemiological connection to those sick based on the sales area.

USA – Big Olaf Ice Cream Listeria Outbreak Joins List of Other Brands

Food Poisoning Bulletin

The Big Olaf Ice Cream Listeria monocytogenes outbreak joins a list of other brands that have caused illnesses over the past decade. The CDC has named Big Olaf ice cream in the new outbreak centered in Florida that has sickened at least 23 people. A recall has not been issued, but the company is contacting their customers to “recommend” against selling their products.

Big Olaf ice cream is only sold in Florida, where most of the ill persons live. And among the 82% of patients who ate ice cream before they got sick and were interviewed by government officials, six said they ate Big Olaf Creamery brand ice cream or ate at restaurants where that ice cream was served.

Over the years there have been dozens of recalls of ice cream for possible Listeria contamination. In fact, in 2019 the FDA improved ice cream production safety after a string of recalls for Listeria monocytogenes contamination. During an investigation that year, the FDA found Listeria monocytogenes in 19 of the 89 ice cream establishments, and in 65 of the 5,295 subsamples.
