Research – Consumer knowledge and behaviors regarding food safety risks associated with wheat flour

Journal of Food Protection

Consumers do not consider flour, a low-moisture food product, a high-risk for microbial contamination. In the past ten years, however, flour has been identified as a source of pathogenic bacteria, including Salmonella and E. coli . Online surveys were conducted to study consumers’ flour-handling practices and their knowledge about food safety risks related to flour. The survey also evaluated message impact on three food safety messages in communicating information and convincing consumers to adopt safe flour handling practices. Flour-using consumers (n = 1,045) from the United States reported they used flour to make cakes, cookies, and bread. Most consumers stored flour in sealed containers. Less than 1% kept a record of product identification numbers, like lot numbers, and less than 11% kept brand and use-by-date information. Many consumers (85%) were unaware of flour recalls, or outbreaks, and few (17%) believed they would be affected by flour recalls or outbreaks. If the recall affected the flour they bought, nearly half of the consumers (47%) would buy the same product from a different brand for a few months before they returned to the recalled brand. Among consumers who use flour to bake, 66% said they ate raw cookie dough or batter. Raw dough “eaters” were more difficult to convince to avoid eating and playing raw flour than “non-eaters.” Food safety messages were less impactful on those raw dough “eaters” than “non-eaters.” Compared with the food safety message with only recommendations, those messages with recommendations and an explanation as to the benefits of the practice were more effective in convincing consumers to change their practices. These findings provide insight into effective consumer education about safe flour-handling practices and could assist in the accurate development of risk assessment models related to flour handling.

Research – Occurrence of Listeria monocytogenes in Counter-Sliced Turkey Meat Samples from Independent Delis in New York City

Journal of Food Protection

Research suggests that small and independent delis are less likely to follow proper sanitation procedures, including slicer inspection, which could lead to a higher likelihood of these delis being a reservoir for Listeria monocytogenes growth and cross-contamination.    This study was undertaken to determine the incidence of L. monocytogenes in counter-sliced turkey deli meat obtained from independent delis in an urban city. Turkey deli meat, counter-sliced on site, was collected from 118 independent delis in New York City. The samples were analyzed for L. monocytogenes using USDA MLG methodology for isolation and confirmation.   The selection criteria for delis included using the city’s restaurant inspection and grading system. Two samples, from separate delis, were confirmed positive for L. monocytogenes (1.69%). Analysis of the genomic sequences of one of the samples revealed a close match to a cluster of 6 clinical isolates, which were part of an ongoing multi-state listeriosis outbreak spanning 4 different states.   The sequence of the second isolate matched a clinical isolate in a neighboring state. Both isolates were obtained from delis that did not have the top inspection grade. Although a snapshot of one urban area, this study is the first report on the current incidence of L. monocytogenes on counter-sliced deli meat from independent deli establishments. This study suggests that these delis can potentially serve as sources of L. monocytogenes contamination or contribute to downstream foodborne listeriosis. Information provided by city inspection and grading systems, in addition to the letter grade, may serve as a tool to identify delis with potential L. monocytogenes contamination issues and serve as a basis for product and environmental sampling by public health authorities.

Ireland – Three Salmonella outbreaks revealed in Ireland

Food Safety News

Irish public health officials have reported three Salmonella outbreaks that have affected at least 34 people.

Two of the three outbreaks were caused by Salmonella Enteritidis and one by Salmonella Mikawasima. Two of the incidents remain unsolved while the third has been linked to chicken products.

Twenty three of the infections have been laboratory confirmed, according to the Health Protection Surveillance Centre (HPSC), Ireland’s agency for surveillance of communicable diseases and part of the Health Service Executive (HSE).

Six people were sickened in the first Salmonella Enteritidis outbreak. Four women and two men had illness onset dates ranging from early June to Oct. 21. Two patients were aged 1 to 2 years old, one was 15-19 years old and three were over the age of 25.

HSE officials told Food Safety News that an investigation has not identified any potential method of transmission including foodborne or source including food.

USA – Colorado: Botulism cases prompt health warning on food safety

Outbreak News Today

Several foodborne botulism cases reported in Colorado since September 2020 has prompted a health warning from the Colorado Department of Public Health and Environment.

Testing from the Centers for Disease Control and Prevention confirmed four of the cases, one is still under investigation and test results are pending. All five cases occurred along the Front Range. The individuals are either hospitalized or recovering.

Three of the cases appear to be unrelated as no common food item was identified. The last two confirmed cases were likely the result of an improperly canned shared food made in the same household.

Portugal – Legionnaires’ disease update: Additional cases/death recorded

Outbreak News Today

CDC legionella

In a follow-up on the Legionnaires’ disease outbreak in northern Portugal region of Greater Porto, officials report from October 29 through November 29, 88 registered cases, including 10 deaths.

The outbreak, which has affected the cities of Matosinhos, Vila do Conde and Póvoa de Varzim, has decreased after the cooling towers of an industry in Matosinhos were disconnected where the bacteria was detected.

“Since the operation of the aforementioned cooling towers was suspended, there has been a marked decrease in the number of cases of Legionnaires’ disease in the aforementioned geographical area,” ARS / Norte said in a statement this Sunday.
