Australia P&O sued over Norovirus-ravaged cruises

The Bharat Express

P&O passengers claim they suffered from diarrhea and vomiting and had to self-isolate in unsanitary conditions after being exposed to norovirus on a number of Australian cruises.

A class action filed in federal court on Tuesday seeks compensation and damages from Carnival, trading as P&O Cruises, for outbreaks of the highly contagious gastrointestinal virus on eight separate voyages from December 2016 to February 2017.

Australia – Investigations into Central Coast Salmonella outbreak continue

NSW GOV AU

NSW Health and the NSW Food Authority are continuing to investigate a significant foodborne outbreak following a conference on the Central Coast last week.

At least 69 people from across NSW, the Northern Territory and Queensland are known to have become unwell with symptoms of food poisoning, of which 27 people have confirmed Salmonella infections to date.

Dr Jeremy McAnulty, NSW Health Executive Director of Public Health, said public health officials from across NSW have been working to speak to all those who have become unwell after attending or working at the conference.

“Close to 230 people attended or worked at the two-day conference, and so far at least 31 of them are known to have attended Emergency Departments,” Dr McAnulty said.

“NSW Health is working closely with the NSW Food Authority to investigate the cause of the outbreak.

“Our public health experts continue to contact people associated with the event, including attendees from the Aboriginal Languages Trust and we thank all of those who have assisted us so far.

Australia – Donuts for weight loss? A norovirus outbreak associated with a bakery in the Australian Capital Territory

Gov Au

Three hundred and one people were surveyed, and 215 individuals (71.4%) reported vomiting and/or diarrhoea following consumption of a donut purchased from the business over a five-day period.
 
All ill respondents reported eating a donut. The medians of incubation period and illness duration were 34 hours (interquartile range, IQR: 29–42 hours) and 48 hours (IQR: 29–72 hours) respectively. Diarrhoea, vomiting and abdominal pain were the most commonly reported symptoms.
 
Eight out of 11 specimens collected from ill individuals were positive for norovirus. For the case-control study, data from 59 attendees were collected, with an attack rate of 46% (27/59). Eating any kind of filled donut was associated with a person becoming ill (odds ratio: 10.4; 95% confidence interval: 1.18–478.13).
 
No single flavour was identified as the likely source of infection.
 
Elevated levels of coliforms were present in two samples of donut filling obtained during the food safety inspection.
 
Conclusion
Donuts are a novel vehicle for norovirus infection. This implicated pathogen, plus evidence collected at the food premises suggestive of faecal contamination, indicates the source of this outbreak was likely an ill food handler. The findings of this outbreak highlight the importance of excluding food
 
 
 

More than 250 ill in UK E. coli outbreak linked to salad

Food Safety News

Vegetable Bacteria Danger

More than 250 people are sick in an E. coli O157 outbreak in the United Kingdom that may have been caused by salad.

There have been 259 confirmed cases in the UK with sample dates ranging from late August to the end of October, although most people fell ill in August and early September.

Shiga toxin-producing E. coli (STEC) O157 has affected people in England, Scotland, Northern Ireland, and Wales. The majority of those sick are adults.

Food Standards Scotland (FSS), the UK Health Security Agency (UKHSA) and Food Standards Agency (FSA) are investigating the outbreak.

It is the largest E. coli outbreak since Whole Genome Sequencing (WGS) started to be used in 2014, according to UKHSA.

Australia – Suspected mass food poisoning at Aboriginal languages conference

SBS

A gathering of Aboriginal language educators on the Central Coast has ended with a number of attendees hospitalised after a case of suspected food poisoning at their hotel.

Participants of the Aboriginal Languages Trust conference attended a gala dinner last Wednesday at the restaurant of the Crowne Plaza Terrigal.

Gamilaraay Yuwaalaraay man Ted Fields told NITV his partner Michelle O’Leary became violently ill just 20 minutes after dinner.
 
The number of attendees taken ill is unconfirmed but some people on social media have said there had been dozens of cases.

Speaking to NITV from Gosford Hospital, where he is still a patient, Mr Fields, 51, said he witnessed multiple attendees being admitted.
 
In a statement to NITV, NSW Health confirmed an investigation into the incident is underway.

“Aboriginal Languages Trust is aware of a number of cases of a gastro-like illness in people who attended a two-day conference held at a Terrigal venue on Wednesday.

“NSW Health is urgently investigating the situation to identify the cause of illness, in collaboration with the NSW Food Authority.”

Research – Microphone-equipped toilet will detect diseases and give you advice – What more can I say :)

Interesting Engineering

In order for patients to be treated for cholera, they must know that they have the disease first. However, it can be a sensitive and difficult task to monitor bowel diseases, such as cholera. Maia Gatlin, a research engineer at the Georgia Institute of Technology, created a way to use artificial intelligence to detect diarrhea. She calls her presentation The Feces Thesis: Using Machine Learning to Detect Diarrhea.

A noninvasive microphone sensor can detect disease in bowels

Gatlin will be presenting her thesis and the sensor tool today, Dec. 5, at the annual Meeting of the Acoustical Society of America, explaining her findings on how machine learning can be used to detect diseases in the bowel. She uses a noninvasive microphone sensor to identify bowel diseases, without necessarily collecting identifiable information, meaning the AI can determine the infection without having to be examined in a medical facility to collect additional data.

Research – German testing finds E. coli in beef, salad, and dough

Food Safety News

E. coli has been found in ground beef, pre-packaged salads, and ready-made dough and baking mixes, according to results of food controls in Germany.

In 2021 risk-based monitoring, samples of ground, or minced, beef was examined. Shiga toxin-producing E. coli were detected in 28 of 420 samples. It was also found in two of 86 tests on fresh beef at retail.

German officials said at-risk consumer groups such as small children, the elderly, immunocompromised people, and pregnant women should only consume ground meat that has been sufficiently cooked.

A total of 88 of 410 ground beef samples tested for Listeria monocytogenes were also positive. Levels were low but can still pose a health risk to vulnerable people. One sample had levels near the legal limit.
