A norovirus outbreak at a New York restaurant was traced back to sick food handlers, some of whom were unaware of the location’s paid sick leave policy, researchers reported at the CDC’s annual Epidemic Intelligence Service conference.

“In December, we received three reports of gastrointestinal illness in patrons [who] dined with a Manhattan restaurant. They were patrons [who] had been part of two different parties that dined on two different days at the same restaurant,” Leah D. Seifu, MD, MPH, Epidemic Intelligence Service with the CDC assigned to the New York City Department of Health and Mental Hygiene, told Healio. “So, we, at the health department decided to investigate these reports of gastrointestinal illness.”

Research – Food safety knowledge and practices among raw meat handlers and the microbial content of raw meat sold at Kumasi Abattoir Butchery Shops in Kumasi, Ghana

BMC

Abstract

Background

Foodborne diseases affect nearly 600 million people each year, that is, one in every ten people, and their outbreaks are most common in low- and middle-income countries, particularly in Africa. This study investigated the food safety practices among raw meat handlers and the microbial quality of the meat from the butchery shops in Kumasi Abattoir, Ghana.

Methods

This study employed a descriptive cross-sectional study and collected quantitative data on factors associated with food safety and hygienic practices among raw meat handlers and the microbial quality of the raw meat using a structured questionnaire and standard laboratory methods, respectively. The study used all 50 beef vending shops in the butchery for questionnaire aspect and fresh beef samples were obtained from 10 vendors in the butchery shop. Appropriate methods were followed to analyse questionnaire data and meat samples.

Results

Most of the butchers (72%) were between the ages of 31 and 45, and they were predominantly Muslims (68%). Most of the respondents (48%) had basic education. All the respondents had food safety certificates from the local authority but needed adequate knowledge of meat safety. Most respondents (90%) handled meat and money with the same bare hands, thus contaminating the meat. The study showed that the maximum Total Viable Count (TVC), Total Staphylococcus Count (TSC), and Total Escherichia coli Count (TEC) were 5.60, 4.39 and 5.13 cfu/g, respectively. The study also revealed that all the meat samples were Salmonella species-free.

Conclusions

Microorganisms in raw beef indicate a public health hazard. It gives a signal of a possible occurrence of food-borne intoxication and infection if not controlled. Environmental health officers in the Greater Kumasi area should organize food safety training and educate raw meat handlers on the importance of food safety and its consequences.

USA- Hepatitis A risk linked to Chick-fil-A food service worker at University of North Dakota

Food Poison Journal

There has been one confirmed case of Hepatitis A in a food worker, possibly exposed following out-of-state travel. No additional cases have been identified at this time.  North Dakota Health and Human Services (HHS) has determined that people who ate at the University of North Dakota (UND) Memorial Union Chick-fil-A, 3625 Campus Rd., Grand Forks, ND, on the following dates and times, may have been exposed to Hepatitis A, which is a contagious liver infection.
January 15, 2024: 5 p.m. – 9 p.m.
January 16, 2024: 11 a.m. – 2:15 p.m.
January 17, 2024: 5 p.m. – 9:45 p.m.
January 22, 2024: 5 p.m. – 9:30 p.m.
January 23, 2024: 11 a.m. – 2 p.m.
January 24, 2024: 5 p.m. – 9:30 p.m.
January 26, 2024: 5 p.m. – 9:30 p.m.
February 4, 2024: 5 p.m. – 8 p.m.
February 6, 2024: 11 a.m. – 2 p.m.
February 7, 2024: 5 p.m. – 8:45 p.m.

Cases can happen in the U.S. in connection to eating contaminated food or drink, person-to-person contact or from other high-risk exposures. It can take about 15 to 50 days (average is one month) after being exposed to Hepatitis A to develop symptoms.

Individuals unsure if they ate food from the UND Memorial Union Chick-fil-A on the specified dates can check credit card purchases or reference their Grubhub app.

USA – Norovirus outbreak that sickened more than 300 people linked to an ill food handler at restaurant

ABC News

The source behind a norovirus outbreak that sickened a few hundred people last year has been identified, according to a report published Thursday by the Centers for Disease Control and Prevention.

The report looked at the outbreak in Tazewell County, Illinois, which includes part of Peoria, which saw 317 people fall ill, all of whom dined at a restaurant — referred to as restaurant A — between Nov. 19, and Nov. 26, 2022.

Investigators with the Tazewell Health Department and Illinois Department of Public Health concluded the outbreak was likely caused by a sick food handler at the restaurant who had ungloved contact with salad, toppings and dressings during food preparation.

Korea – Wash hands after touching eggs: Food agency warns of salmonella outbreak

Korean Herald

Food safety authorities on Wednesday warned people to wash hands promptly after handling or cooking raw eggs, citing food poisoning risks from Salmonella, a harmful bacterium found in poultry and mammal intestines.

There have been numerous cases of food poisoning caused by cross-contamination, where individuals handle eggs and then fail to wash their hands before cooking food or touching other cooking utensils, according to the Ministry of Food and Drug Safety.

USA – Taco Bell employee infected with Hepatitis A; county in Washington issues health alert

Food Safety News

Health officials in Snohomish County, WA, are warning people who ate at two Taco Bell locations to monitor themselves for signs of hepatitis A infections and get vaccinated if they are not already.

“People who ate food from the Taco Bell at 2727 Broadway on May 22-23 or the Taco Tell at 303 91st Avenue NE in Lake Stevens on May 23 should contact their healthcare provider or public health,” according to the warning from the Snohomish County Health Department.

An employee who worked at both locations has tested positive for hepatitis A. The confirmed case appears to have been infected during international travel. The Snohomish County Health Department is working with the business to identify other workers who were potentially exposed and connect them with prevention information as well as resources for vaccination and post-exposure prophylaxis, as needed.

For two weeks after exposure a vaccination is effective from keeping the liver virus from developing. Therefore it is crucial for anyone who ate at the restaurants on the exposure dates to check their vaccination records.

Research – Rare Recombinant GI.5[P4] Norovirus That Caused a Large Foodborne Outbreak of Gastroenteritis in a Hotel in Spain in 2021 – Food Handler

Journals ASM

Noroviruses are among the most important causes of acute gastroenteritis (AGE). In summer 2021, a large outbreak of norovirus infections affecting 163 patients, including 15 norovirus-confirmed food handlers, occurred in a hotel in Murcia in southeast Spain. A rare GI.5[P4] norovirus strain was identified as the cause of the outbreak.
The epidemiological investigation determined that norovirus transmission might have been initiated through an infected food handler. The food safety inspection found that some symptomatic food handlers continued working during illness. Molecular investigation with whole-genome and ORF1 sequencing provided enhanced genetic discrimination over ORF2 sequencing alone and enabled differentiation of the GI.5[P4] strains into separate subclusters, suggesting different chains of transmission. These recombinant viruses have been identified circulating globally over the last 5 years, warranting further global surveillance.
IMPORTANCE Due to the large genetic diversity of noroviruses, it is important to enhance the discriminatory power of typing techniques to differentiate strains when investigating outbreaks and elucidating transmission chains. This study highlights the importance of (i) using whole-genome sequencing to ensure genetic differentiation of GI noroviruses to track chains of transmission during outbreak investigations and (ii) the adherence of symptomatic food handlers to work exclusion rules and strict hand hygiene practices. To our knowledge, this study provides the first full-length genome sequences of GI.5[P4] strains apart from the prototype strain.

Research – Far-UVC Radiation for Disinfecting Hands or Gloves?

MDPI

Abstract

(1) Background: Far-UVC radiation in the spectral range 200–230 nm has, according to previous findings, a strong antimicrobial effect on pathogens, but exhibits hardly any harmful effect on human skin. Therefore, the present study will discuss whether such radiation could also be suitable for hand disinfection in the healthcare sector. (2) Methods: Hands and gloves were microbially contaminated and exposed to radiation from a 222 nm krypton-chloride-excimer lamp. The applied doses were 23 mJ/cm2 and 100 mJ/cm2, respectively. Irradiated and non-irradiated hands and gloves were pressed onto agar plates and colonies were counted and compared after 24 h of incubation. For comparison, we also treated hands and gloves with a commercial liquid alcohol-based disinfectant. (3) Results: On the hand, the 23 mJ/cm2 resulted in the reduction of the observed colonies on the agar plates by one log level. For the gloves irradiated with 100 mJ/cm2, a colony reduction of 1.3 log levels was recorded. In the comparative experiments with the commercial disinfectant, a colony reduction of 1.9 and approximately one log level was observed on hand and gloves, respectively. (4) Conclusion: In both cases, far-UVC radiation provided a considerable reduction in microorganisms. However, compared to published far-UVC irradiation results in suspensions, the disinfection success on hands and gloves was rather low. With regard to the irradiation limits currently existing in the European Union, multiple daily hand disinfection with far-UVC radiation is actually legally not possible at present, but the thresholds are currently under discussion and could change in the future. Far-UVC disinfection of hands in gloves seems theoretically possible if attention is paid to potential perforations in the gloves.

Research – An outbreak of Hepatitis A virus infection in a secondary school in England with no undetected asymptomatic transmission among students

Cambridge Org

Abstract

In June 2019 the Health Protection Team in Yorkshire and Humber, England, was notified of cases of hepatitis A virus (HAV) infection in staff at a secondary school. Investigation revealed that an earlier case worked as a food handler in the school kitchen. Indirect transmission through food from the canteen was considered the most likely route of transmission. Cases were described according to setting of exposure. Oral fluid was obtained from students for serological testing. Environmental investigations were undertaken at settings where food handling was considered a potential transmission risk. Thirty-three confirmed cases were linked to the outbreak. All of those tested (n = 31) shared the same sequence with a HAV IB genotype. The first three cases were a household cluster and included the index case for the school. A further 19 cases (16 students, 3 staff) were associated with the school and consistent with indirect exposure to the food handler. One late onset case could not be ruled out as a secondary case within the school and resulted in vaccination of the school population. Five cases were linked to a bakery where a case from the initial household cluster worked as a food server. No concerns about hygiene standards were noted at either the school or the bakery. Oral fluid samples taken at the time of vaccination from asymptomatic students (n = 219, 11–16 years-old) showed no evidence of recent or current infection. This outbreak included household and foodborne transmission but limited (and possibly zero) person-to-person transmission among secondary school students. Where adequate hygiene exists, secondary transmission within older students may not occur.
