Listeria in rockmelon: ‘Misinformation’ is language of deniers

On Sept. 9, 2011, reports first surfaced of an outbreak of Listeria linked to cantaloupe – known as rock melons in Australia — grown in Colorado. Already two were dead and seven others sick.

By the end of the outbreak, 33 people were killed and at least 140 sickened.

On Aug. 17, 2012, the U.S. Centers for Disease Control announced an outbreak of Salmonella linked to cantaloupe that ultimately killed three people and sickened 270 in 26 states.

In Australia, a third death has now been linked to the Listeria-in-rockmelon outbreak, and the number of sick people has risen to 12.

Already, an Australian rockmelon grower is saying “misinformation” about the listeria outbreak will have a negative impact on growers.

The only misinformation – or fake news – is the lack of information to regain consumer confidence and trust.

Sadly, the number of dead and sick will probably grow, because Listeria has an incubation period of up to six weeks. The melon you ate five weeks ago could make you sick with listeriosis tomorrow.

This is not misinformation, it’s biology.

A table (that needs to be updated) of cantaloupe-or-rockmelon-related outbreaks is available here.

Listeriosis linked to rockmelon in Australia

About a week ago I was chatting with our contractor – we really spend too much time chatting instead of working, and Amy often intervenes – and somehow we got on about the microbiological risks of cantaloupe (or rockmelon as they call it here).

This morning Australians awoke to the news from the NSW Food Authority that two people have died and eight were sick from Listeria-linked to cantaloupe (not the 3 dead and 7 sick reported earlier).

All states and territories are working together to investigate the outbreak and to date they have identified ten cases in elderly patients in NSW (six), Victoria (one) and Queensland (three) with onset of illness notification dates between 17 January and 9 February 2018. All 10 cases consumed rockmelon prior to their illness.

The outbreak has been linked to a grower in Nericon NSW. The company voluntarily ceased production on Friday 23 February 2018, shortly after being notified of a potential link to illness and is working proactively with the Authority to further investigate how any contamination could have occurred in order to get back into production as soon as possible.

Any affected product is being removed from the supply chain, so consumers can be assured rockmelons currently available on shelves are not implicated in this outbreak, but people may already have listeria-infected rockmelons in their homes purchased at an earlier time.

Contaminated water, fertiliser, contact with animals or insufficient cleaning of rockmelons prior to sale are all risk factors for melons becoming contaminated.

The contamination is on the fruit’s skin, not in the flesh.

NSW Health director of communicable diseases Vicki Shepherd said, “If there are levels of listeria on the skin then when you cut it, it can be transferred into the surface where you then eat it.”

Our contractor said today, did you see the news, guess Doug knows a thing.

It’s easy to know a thing if you pay attention. Rockmelons have been repeatedly linked to previous cases of listeria, including an outbreak that killed 33 Americans in 2011.

It’ll still be served in hospitals: 3 dead, 7 sick from Listeria-in-cantaloupe in Australia

Listeria monocytogenes has been found on a number of rockmelons from a supplier in New South Wales (NSW, that’s in Australia).

The discovery comes after reports of an outbreak of listeriosis in the Australian state, following an unexpected increase in cases in January and February.

While the link between the farm and the illness cases is not yet conclusive, PMA Australia-New Zealand (PMA A-NZ) said there was sufficient circumstantial evidence to warn at-risk consumers not to consume rockmelon.

“At least 10 people have become infected including three deaths,” PMA A-NZ said in a release. “All cases are people in high risk groups, which includes those who are older, pregnant or have underlying health conditions,”

The NSW Food Authority and NSW Health are currently investigating the outbreak.

Listeriosis is caused by consuming food contaminated with Listeria monocytogenes. Listeria is a bacteria that survives and grows on a number of foods including rockmelon, vegetable salads and fruit salads, cold meats, raw seafood, soft cheeses and seed sprouts.

 

But what does gastro mean? Outbreak hits University of Queensland students

I don’t know what it is about Australians, whether it’s some pseudo-inherited British culture of hierarchy, or just dumbness, but lately, any outbreak of barfing and pooping is called a gastro outbreak.

As in gastroenteritis.

There are microbiology labs in Australia, so figure it out, and let people know.

Janelle Miles of The Courier Mail reports 20 students at two University of Queensland residential colleges have fallen ill with gastroenteritis in the middle of orientation week.

The students are residents of King’s College and Grace College at UQ’s St Lucia campus in Brisbane’s west.

They have been quarantined separated from other students to avoid the infection spreading.

Was it foodborne? Are there any epidemiologists in Australia? Is anyone investigating?

Australian student who sold monkey skull to ‘people from Pirates of the Caribbean’ fined

A few years ago, one of those Johnny-Depp-pirate movies — it may have been 5 — was filming down the highway at the Gold Coast.

The set was plagued by drama when it was discovered Depp and then wife Amber Heard had illegally brought two dogs into the country.

This prompted deputy premier Banaby-the-bloody-carp Joyce (right, not exactly as shown) to question Depp’s acting ability after the couple apologized, which shows how small Australia is because now Joyce is embroiled in his own scandalous activities, involving humans, not pets.

Behind the sideshow of movie making, divorce and apologies, a Canberra university student was on Thursday fined for illegally possessing and importing exotic animal remains into Australia, in a case that has shed some light on the shadowy world of wildlife trade.

Alexandra Back of the Canberra Times reports that for years, avid collector Brent Philip Counsell, 28, dealt in what a magistrate described as a “macabre” trade of skulls and animal specimens, once selling a primate skull to the people making the Pirates of the Caribbean movie in Brisbane.

In 2016 authorities from the department of environment raided Counsell’s home in Deakin where they found and seized about 100 animal specimens from the living room and bedroom.

Australian environment law makes it illegal to either possess or import protected exotic animal specimens without a permit.

Over several years, Counsell either illegally imported or possessed a small primate skull threaded on a necklace, the skulls of a brown bear and a gibbon, a taxidermy buzzard, water monitor lizard, and teeth from a bear and a hippopotamus tooth.

When he spoke to investigators, Counsell admitted possessing and selling species from his website wulfe.com.au, which he had since shut down.

One of the charges stemmed from an admission Counsell made to authorities after they had searched his home, that he had sold a primate skull to the “people” behind the Pirates of the Caribbean movie that was filming in Brisbane.

He tried to avoid detection, and prosecutors found on his phone articles that offered tips about how to send skulls overseas without being noticed by customs.

Whole genome sequencing is just a technique, with pros and cons: Australia still has a (raw) egg problem

In Australia, the incidence of Salmonella Typhimurium has increased dramatically over the past decade. Whole-genome sequencing (WGS) is transforming public health microbiology, but poses challenges for surveillance.

To compare WGS-based approaches with conventional typing for Salmonella surveillance, we performed concurrent WGS and multilocus variable-number tandem-repeat analysis (MLVA) of Salmonella Typhimurium isolates from the Australian Capital Territory (ACT) for a period of 5 months. We exchanged data via a central shared virtual machine and performed comparative genomic analyses. Epidemiological evidence was integrated with WGS-derived data to identify related isolates and sources of infection, and we compared WGS data for surveillance with findings from MLVA typing.

We found that WGS data combined with epidemiological data linked an additional 9% of isolates to at least one other isolate in the study in contrast to MLVA and epidemiological data, and 19% more isolates than epidemiological data alone. Analysis of risk factors showed that in one WGS-defined cluster, human cases had higher odds of purchasing a single egg brand. While WGS was more sensitive and specific than conventional typing methods, we identified barriers to uptake of genomic surveillance around complexity of reporting of WGS results, timeliness, acceptability, and stability.

In conclusion, WGS offers higher resolution of Salmonella Typhimurium laboratory surveillance than existing methods and can provide further evidence on sources of infection in case and outbreak investigations for public health action. However, there are several challenges that need to be addressed for effective implementation of genomic surveillance in Australia.

35 now sick, 9 hosiptalized in South Australian Salmonella outbreak; bakery reopens

Confirmed cases of salmonella, linked to a South Australian bakery, have climbed to 35 with more expected as tests continue.

SA Health says nine people, including two children, have been hospitalised after eating products from the Gawler South bakery, which has two outlets in Gawler, about 40km north of central Adelaide.

The link to the bakery was first revealed late last month.

“We’ve now seen cases in people aged two years to 70 years old and we are anticipating more cases as further test results come through,” SA Health’s director of public health Kevin Buckett said.

The source of the contamination had been linked to sandwiches, wraps, rolls and focaccias with chicken and other fillings.’’

In a statement posted on social media the bakery’s management said it was no longer cooking chicken on the premises and SA Health officials were happy with its food handling processes.

Management also apologised to anyone who had become sick. “We hope this apology is received to be genuine and in good faith,” the statement said.

According to the ABC, the bakery was also struck by a salmonella outbreak in October 2016 which affected eight people.

Australia still has an egg problem: Over 200 with Salmonella across NSW as temps rise

Providing food safety advice without preaching is tricky.

Matching the advice with what happens in reality is damn hard.

Amy, Sorenne and I are hanging out in Canberra – Australia’s capital — for the next couple of days while Amy goes to a French conference and Sorenne teaches me how to play Minecraft.

Dinner last night, including chicken wings and potato-somethings, were both served with aioli.

I asked the server, how was the aioli prepared, is it a commercial product or is it made with raw eggs?

Oh, we make our own aioli. We would never buy the commercial product.

No thanks.

Amy said, serve it on the side, I’ll take the risk.

So did Sorenne, although we did have a chat about microbiology (seize those learning moments).

This in context of health authorities warning people to take precautions to prevent salmonella poisonings, with 201 cases already reported in late November as temperatures start to climb.

Of the 4.1 million cases of food poisoning in Australia each year around a third of reported outbreaks are linked to raw or lightly cooked eggs.

Dr Vicky Sheppeard, Directors of Communicable Diseases at NSW Health said the best defence against salmonellosis was careful food preparation and food storage.

“Products containing undercooked eggs, and the spread of germs in the kitchen, are the most common source of salmonellosis outbreaks in NSW.”

NSW Food Authority CEO Dr Lisa Szabo said using commercially produced products instead of handmade mayonnaise and sauces when preparing food also reduced the risk of Salmonella poisoning.

“It is also much safer to use commercially pasteurised eggs rather than raw eggs in ready-to-eat products such as desserts and dressings,” DrSzabo said.

Good luck with that.

 

Australian bakery that sickened 203 with Salmonella in 1996 fined $130K

In late Jan. 2016, a bakery in Sydney’s south was closed as customers started reporting Salmonella illness.

On Monday, the owners of the Box Village Bakery, Thi Thu Ngo and Hung Son Le, were fined a total of $122,000 and ordered to pay $7,199 professional costs after each was convicted of ten breaches of the Food Act 2003.

The owners the Sylvania bakery at the centre of a Salmonella outbreak that affected more than 200 people, each pleaded guilty to five breaches of selling unsafe food, and five breaches of failing to meet food safety standards and were fined $61,000 each.

There were 203 documented cases of people who had presented to hospitals and other health care providers with symptoms of gastroenteritis including vomiting, diarrhea and fever after consuming bakery items such as chicken rolls and salads that were linked back to the bakery.

During its investigation the NSW Food Authority issued a Prohibition Order requiring the business to cease operations.

The business was only permitted to reopen and trade after it completed extensive work to ensure the bakery had been thoroughly cleaned and fully compliant with food safety laws.

The NSW Food Authority also conducted skills and knowledge testing with staff and management of the business to improve their food safety knowledge and conducted a number of inspections of the premises subsequent to its reopening to ensure it continued to be fit to trade.

CEO of the NSW Food Authority Dr Lisa Szabo said the court result served as a reminder to all food businesses and individuals as to why food safety systems are crucial.

Australia: still has an egg problem: 17 major salmonella outbreaks for Adelaide in 2016/17 linked to pork and eggs

The almost southern most state of Australia, South Australia has a population of 1.7 million people, and yet almost 1,200 South Australians were stricken by food poisoning in the past 12-months.

Katrina Stokes of The Advertiser writes that according to the 2016/17 Health Department report, 17 food poisoning investigations conducted by officials revealed that dairy, poultry and meat products were responsible for the salmonella outbreaks.

New figures from SA Health reveal there have been a total of 1182 salmonella cases so far this year, compared to a total of 1561 in 2016.

Alarmingly, of this year’s cases, 17 per cent have been in children aged five or younger.

The biggest outbreak was at the InterContinental Hotel on July 31 last year after guests ate the buffet breakfast — and the cause was linked to cross contamination from eggs.

Of 140 people who reported feeling unwell, 85 were confirmed cases of salmonella and 20 were admitted to hospital.

Patients were treated for vomiting, diarrhoea, fever and headaches.

Other food poisoning cases in 2016/17 included:

CHILDREN at an out-of-hours care facility were struck down with gastroenteritis and an investigation identified one source was inadequate sanitation procedures in the kitchen. Some of the children also reported consuming eggs in an uncooked cupcake mixture. A total of 24 children were sick and 12 cases confirmed.

WEDDING guests fell ill after eating food, including chicken liver parfait and chicken galantine, at a restaurant. One food poisoning case was confirmed and a total of 12 people were sick.

DODGY egg sandwiches and wraps from a bakery caused a total of eight people to get sick. The source was the egg supplier.

Earlier this year, at least 14 people got sick after eating pork pies from the Pork Pie Shop at Victor Harbor.

An inspection of the bakery identified problems including possible contamination from raw egg wash used on the pies, inadequate storage temperature and cleaning of sanitising of equipment.

A total of 33 people got sick from a rare form of salmonella after eating rockmelon from an interstate producer in July 2016.

SA Health director of food and controlled drugs Dr Fay Jenkins said the exact cause of salmonella was often hard to pinpoint — but eggs, and egg handling, were often the culprit.

“To reduce the risk of sickness, do not use eggs if they are cracked or dirty, wash your hands after handling eggs and keep raw egg products like aioli, mayonnaise and mousse refrigerated,” she said.

How about, cook eggs.
