USA- Virgin Voyages’ Scarlet Lady reports gastroenteritis on cruise ending today – Norovirus?

Sea Trade

During Scarlet Lady’s current five-day cruise, just above 3% of passengers experienced symptoms of acute gastroenteritis, commonly referred to as stomach flu.

‘Our medical team isolated these travelers, and we immediately enacted enhanced sanitization procedures including additional cleaning of cabins and high-contact areas around the ship,’ a Virgin Voyages spokesperson said. ‘We are working closely with the CDC and their medical professionals. There is currently no impact to the upcoming voyage’s departure time or ports of call.’

Norovirus caused the most outbreaks and illnesses in 2022, according to the Swedish Food Agency (Livsmedelsverket).

Overall, there were 337 reports of suspected or confirmed foodborne illnesses to the agency with 2,261 cases of illness. In 303 events, two or more people were infected from the same source. This is up from 251 outbreaks with 1,467 patients in 2021.

In 2022, the number of food poisonings returned to the level seen before the COVID-19 pandemic. The increase in outbreaks and illnesses began in late 2021, when several restrictions imposed during the pandemic were lifted.

The number of incidents peaked during the last six months of 2022. This was because of four large outbreaks with more than 100 patients during September and December.

USA – CDC Solves Norovirus Mystery On The Pacific Crest Trail

Although the REDCap survey identified only 27 ill hikers, social media reports indicated that the true size of the outbreak was likely substantially larger, with 27 reports with a date of onset, and numerous others without further chronologic information apart from the year (2022). Norovirus prevention in remote areas is difficult because of a lack of easily available clean water and soap for handwashing, and inability to routinely disinfect shared surfaces (e.g., cabins and restrooms). Moreover, alcohol-based hand sanitizers, commonly used in hiking, are not effective against norovirus (5). Preventing future outbreaks will require fostering increased awareness of the importance of handwashing and lack of effectiveness of alcohol-based hand sanitizers against norovirus, and more frequent cleaning of public facilities; early outbreak detection might be facilitated by social media surveillance.

When two outbreaks occur in the same institution within a short period of time, an important health and social concern is generated. Two gastroenteritis outbreaks occurring a week apart in the same facility were reported in Lleida, Spain, in 2018. The objective of this study was to describe the clinical, epidemiological and microbiological investigation carried out and to determine the risk factors. Demographic data, food consumption and symptoms were collected. Health inspections of the facility were carried out. Risk ratio and their 95% confidence intervals were estimated for the implication of each food consumed. The attack rate was 89.7% in the first outbreak and 69.6% in the second outbreak. The most frequent symptoms in the first and second outbreak were abdominal pain (88.5% and 100%, respectively), vomiting (80.8% and 87.5%, respectively) and nausea (69.2% and 81.3%, respectively). The first outbreak was associated with the consumption of a salad and the second with a cheese omelet. Norovirus GII.6 was detected by RT-PCR and sequenced in both groups of students and in the food handlers who prepared the meals. These results highlight the importance of exclusion from work of food handlers with gastroenteritis, the adequate availability of mechanisms for correct hand washing and the correct cleaning of surfaces.

FAO and WHO plan meeting on foodborne viruses

Food Safety News

The UN Food and Agriculture Organization (FAO) and World Health Organization (WHO) are set to hold an expert meeting on viruses in food later this month.

The Joint FAO/WHO Expert Meeting on Microbiological Risk Assessment (JEMRA) event, at FAO headquarters in Rome on Sept. 18 to 22, will work on food attribution, analytical methods, and indicators of viruses in foods.

United States-based experts proposed for the meeting are Donald Schaffner, of Rutgers University; Xiang-Jin Meng, at Virginia Tech; Kali Kniel, from the University of Delaware; Lee-Ann Jaykus, at North Carolina State University; and Jacquelina Williams-Woods of the FDA.

In 2022, the Codex Committee on Food Hygiene (CCFH) asked JEMRA to provide scientific advice to inform a review of guidelines established in 2012. This was due to emerging issues associated with foodborne viruses and scientific developments.

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.

USA – FDA Advises Restaurants, Retailers and Consumers to Avoid Certain Fortune Brand Raw Oysters from Nova Scotia Contaminated with Norovirus

FDA

Audience

Restaurants and food retailers that have received shipments of oysters harvested from NS 10, an oyster harvest area in Nova Scotia, Canada on June 9, 2023, and were distributed by Bill and Stanley Oyster Co. of Nova Scotia, Canada through U.S. distributors to 17 states and the District of Columbia: CA, CO, CT, DC, DE, FL, GA, IN, MA, MD, MI, MN, NJ, NY, OH, PA, TX, and WI. The FDA is working to obtain additional information on distribution of the oysters and will continue to monitor the investigation, provide assistance to state authorities, and update our communications to the public as needed.

Consumers, especially those who are or could become pregnant, the elderly, and persons with weakened immune systems, who have recently consumed raw oysters and suspect they have food poisoning should seek medical care immediately.

Contaminated shellfish can cause illness if eaten raw, particularly in people with compromised immune systems. Food contaminated with norovirus may look, smell, and taste normal. Consumers of these products who are experiencing symptoms of norovirus illness should contact their healthcare provider, who should report their symptoms to their local Health Department.

Summary of Problem and Scope

On June 30, 2023, the Minnesota Department of Health (MDH) reported to CDC an outbreak consisting of 9 cases of norovirus illness associated with the consumption of oysters from Nova Scotia. The oysters harvested from Nova Scotia were sold in both Canada and the U.S. FDA is working with federal, state, and local officials, and with Canadian public health authorities to investigate this outbreak, obtain additional information on distribution of the oysters, and determine if additional illnesses have occurred.

Retailers should not sell or serve raw oysters from harvest location NS 10 with a harvest date of June 9, 2023, which will be printed on product tags.
