Bullshit: Australian rockmelon Listeria investigation finds outbreak that killed seven largely caused by dust storm

(thanks to the avid barfblog.com reader who forwarded this)

An investigation into a series of deaths linked to listeria on rockmelons has concluded the contaminated fruit came from a single farm in New South Wales, and the outbreak was largely caused by the weather.

Between January 16 and April 10, 22 cases of listeriosis occurred across New South Wales, Victoria, Queensland and Tasmania, which led to seven deaths and a miscarriage.

Key points:

The investigation found the farm that was the source of the outbreak had hygiene and sanitary procedures on par with or better than most rockmelon-growing operations

Dust storms that covered the farm’s paddocks significantly increased the amount of listeria on the fruit

There were other peripheral issues found in the packing facility that were not considered to be major underlying causes

A report released on Thursday by the NSW Department of Primary Industries confirmed those cases were all linked to consumption of rockmelon packed at Rombola Family Farms in Nericon, NSW.

The report said the farm’s hygiene and sanitary procedures were “on par with or better than most other rockmelon-growing operations across Australia”.

Despite this, heavy rains in December and dust storms that followed covered the farm’s paddocks in dust, and “significantly increased” the amount of listeria on the fruit.

Rockmelons on the farm were washed in a chlorine solution and scrubbed prior to packing.

“The wash water was not recirculated, sanitiser was constantly monitored and applied through an auto-dosing system, and all water coming into the facility was treated and considered potable,” the report said.

“The netted skin of rockmelons makes this fruit particularly hard to clean and sanitise.”

The report said there were other peripheral issues noted in the packing facility during the investigation.

These included some dirty fans that were used to reduce the level of moisture on melons after washing, and some spongy material on packing tables that was not able to be easily cleaned.

These may have been contributing factors to the outbreak but were not considered to be the major underlying causes.

The report said the outbreak highlighted the need for better control measures and awareness of external threats to food safety in the rockmelon indstury.

As more cases of listeriosis emerged, sales of rockmelon plummeted and failed to recover.

Many rockmelon growers called for the farm that was the source of the outbreak to be named, in order to reassure the public that the fruit was safe to eat.

Australia still has an egg problem: 23 sick but Salmonella egg farm says ‘not my fault bro’

This story is a month old, but I thought I’d wait and see if there was any follow-up communication with the mere egg-consuming mortals of the public.

There was none.

On Sept. 8, 2018, the New South Wales Food Authority issued a statement saying it was advising that ‘Eggz on the Run’ is undertaking a voluntary recall of Glendenning Farms eggs as part of an investigation into human illness.

A cluster of human cases of Salmonella Enteritidis, have been detected in the Sydney area. To date there have been 23 confirmed cases.

Eggz On the Run lawyer Raed Rahal the Sunday Telegraph the family which ran the company was “not even certain that the outbreak is in the eggs

“The strain is from overseas.

“There was only a certain batch that was supposed to be removed but the company has voluntarily decided to remove all batches of eggs.”

He said the family was “shell-shocked by the news as it is their livelihood”.

“They would certainly not do anything to risk anyone’s safety,” Mr Rahal said.

Customers who purchased the eggs can return the product for a full cash refund.

The egg farmer linked to the latest Salmonella poisoning outbreak has said “it’s not my fault bro” and blamed foreign birds flying in and defecating on his poultry sheds.

In an epidemiologically outrageous claim following the 23 illnesses, the Glendenning Farms worker at Cobbitty in southwestern Sydney has denied any blame.

The farmer, who has been producing eggs for 20 years, told The Sunday Telegraph the salmonella outbreak came from “something to do with the birds.

“Some birds have been flying in from overseas, landed on the shed and chucked a s**t,” he said.

“Even the Food Authority said it wasn’t my fault,” the man said from the farm run by EggzOn the Run.

Back to you, defenders of public health.

How to stop food sabotage

Last Sunday, Sept. 16, 2018, I had a requested op-ed published in the Sydney Morning Herald. I was a little rusty, so Amy did more than just clean it up, and I haven’t gotten around to posting it until now because there was some medical stuff last week, but all is well and here it is:

My 9-year-old daughter and I were watching the news on Saturday morning and she asked, why would someone put a needle in strawberries?

Some people are not nice.

A couple of years ago a food safety type asked me, what’s the biggest risk to the food supply.

I didn’t hesitate.

Deliberate tampering and food fraud.

Food safety has traditionally been faith-based – especially when it comes to fresh fruit and vegetables. Consumers cannot control how food is handled before it gets to them. This is why consumers need to know their suppliers and know what they are doing to keep people safe.

This latest food tampering scare – 11 cases of contaminanted strawberries reported nationally so far, the first in Sydney on Saturday – makes that clear.

Faith-based food safety sucks. It always has. Risks have always been present. As Madeleine Ferrieres, the author of Mad Cow, Sacred Cow: A History of Food Fears,  wrote, “All human beings before us questioned the contents of their plates.”

But contemporary consumers forget that contamination risk has always been with us: “We are often too blinded by this amnesia to view our present food situation clearly. This amnesia is very convenient. It allows us to reinvent the past and construct a complaisant, retrospective mythology.”

“We still live with the illusion of modernity, with the false idea that what happens to us is new and unbearable,” she has said in an interview.

What’s new is that we have better tools to detect problems. This also presents an opportunity: those who use the best tools should be able to prove their food is safe through testing and brag about it. They can market food safety measures at retail.

The days of faith-based food safety are coming to a protracted close.

There is a lack – a disturbing lack – of on-farm food safety inspection; farmers need to be more aware of the potential for contamination from microbes (from listeria in rockmelon, for example) as well as sabotage.

There is an equally large lack of information to consumers where they buy their produce. What do Australian grocery shoppers know of the food safety regulations applied to the produce sold in their most popular stores? Who can they ask to find the answers?

The best solution is for farmers and retailers to market food safety. If they have a great food safety program they should be promoting it. Consumers can handle more information rather than less.

Needles in Australian produce: Copy-cats, metal detector sales and stiff penalties for ‘cowards and grubs’

With more than 100 reports of tampered fruit being investigated by police across Australia, an Adelaide father has been charged over a fake needle-in-strawberry report.

Police say the 34-year-old last week reported that his daughter bit into a strawberry purchased at a local supermarket and that it was contaminated with a needle.

The arrest comes as the hunt for those responsible for sticking needles in strawberries continues, and the federal government ramps up penalties for so- called “food terrorists.”

Food tamperers could spent 10 to 15 years behind bars under draft laws passed by the government on Thursday.

One young boy in NSW has already been arrested over behaviour that “could be called a prank”, police said, and he will be dealt with under the youth cautioning system.

The warning comes as Prime Minister Scott Morrison looks to punish ‘cowards’ who purposely contaminate food.

Culprits could face up to 15 years jail under tough updates to food contamination laws the PM will urgently push through parliament this week.

And “idiots” who post Facebook hoaxes about fake contamination cases could face up to 10 years in jail under new measures to deal with “reckless” behaviour.

‘Sabotage’ laws will also be updated to include the sabotage of “goods for human consumption” where it impacts national security.

“Any idiot who thinks they can go out into a shopping centre and start sticking pins in fruit and thinks this is some sort of lark or put something on Facebook which is a hoax, that sort of behaviour is reckless and under the provision we will be seeking to introduce swiftly, that type of behaviour would carry a penalty of up to 10 years in prison,” Prime Minister Morrison said today.

“It’s not a joke. It’s not funny. You are putting the livelihoods of hard-working Australians at risk and you are scaring children,” he said.

“You are a coward and a grub. And if you do that sort of thing in this country we will come after you and we will throw the book at you.”

Meanwhile, the strawberry scandal’s costing the industry millions of dollars, but it’s created a booming trade for one food safety company.

A&D Australasia provides metal detectors to food production companies, and their sales in the last week – including in New Zealand – have skyrocketed.

Spokesperson for the company Julian Horsley says he’s sold a year’s worth of products in just four days.

“There’s an element of panic obviously because customers are saying we can’t buy your product until this and this are in line – so that’s obviously a commercial panic to them” he said.

Each detector costs around $22,000, but Horsley says growers are viewing them as an investment.

“For these guys it’s either put my produce in the rubbish bin, or supply it to the customers.”

Man swallows needle in strawberry bought from Woolworths Australia

Queensland, with its sub-tropical climate, has fabulous produce and seafood.

Even if regulators are a bit dopey about food safety.

Jill Poulson and Tanya Westthorp of the Courier-Mail report health authorities are warning people who have bought strawberries in Queensland, NSW and Victoria to throw the punnets out after several incidents of needles being found in strawberries sold at Woolworths.

Queensland Health and Queensland Police today took the extraordinary step to urge people who bought strawberries across the eastern seaboard in the past week to throw them out after three separate incidents in Queensland and Victoria.

Police suspect the ground-down needles were deliberately planted in the punnets with the culprit intending to cause ‘grievous bodily harm or other objectives’.

The contaminated strawberries come from one farm and are sold under the brands ‘Berry Obsession’ and ‘Berry Licious’. They are sold from Woolworths and it’s believed they may also be sold at other stores. A product recall is underway.

It comes as a 21-year-old Burpengary man ended up in hospital after he swallowed part of a needle when he bit into a strawberry bought from Strathpine in Brisbane’s north on Sunday.

Two more incidents in Victoria were confirmed yesterday.

Don’t get shot in America. Live in Australia


Building on what John Oliver, then of the Daily Show, started five years ago, Damien Power writes in The New York Times there are more than 393 million civilian-owned firearms in the United States, which means there are more guns than people. If that makes you feel unsafe, visit Australia.

In Australia, it took one mass shooting in Port Arthur in 1996, where 35 people were killed, for the country to do something concrete about gun reform. The government adopted tighter gun control, banned semiautomatic weapons and started a mandatory gun buyback program.

The United States, meanwhile, has an average of nine mass shootings every 10 days, and 13,000 gun homicides a year. Gun violence is so rampant that China has warned its citizens about traveling here.

So if you’re interested in not getting shot to death and adorable koalas, Australia might be the place for you. Not being the target of snipers adds to the magic of visiting Down Under.

I’d add don’t barf and visit Aus, but food safety controls aren’t as good as gun controls.

EU Listeria-in-frozen veg outbreak hits Australia

The Listeria-in-frozen veg outbreak in the EU that has killed nine and sickened 47 since 2015 has taken an Australian twist: the vegetables distributed by Belgium-based frozen food distributor Greenyard Frozen NV were also distributed in Australia (and who knows where else) underlying the role of bullshit and faith regarding global food safety.

Food safety is, of course, any distributor’s first priority (as Sorenne asked me today, about something completely different, “was that sarcasm?”

Nothing funny about this.

A whole bunch of frozen veg stocked by Woolworths, IGA and ALDI in Australia have been added to the recall by Food Standards Australia New Zealand (FSANZ).

FSANZ spokeswoman Lorraine Haase said there had not been any evidence of infections in Australia, but a number of people had died in the United Kingdom.

Two days later, on July 11, 2018, the Victorian Department of Health and Human Services identified a case of Listeria from earlier in 2018 that has now been linked to the strain in Europe which has led to a recall of a range of imported frozen vegetables.

The listeria is the same serotype with similar genetics.

Unfortunately, the Victorian case who was being treated for another serious illness died earlier this year.

So it is not possible to confirm whether this person actually consumed any of the frozen vegetable products.

This is not the same serotype of Listeria which killed seven in Australia and caused one miscarriage after consumption of rockmelon earlier this year.

Listeria can be anywhere, and it is up to food producers and merchants to provide rapid, reliable, relevant and repeated information about these outbreaks, which, based on conversation at a hockey tournament in New South Wales this weekend, are starting to permeate the consciousness of shoppers in Aus.

Patterns of crypto in Australia

Cryptosporidium is a protozoan parasite that causes the diarrheal disease, cryptosporidiosis. Although many species have been identified, the majority of human disease worldwide is caused by two species; Cryptosporidium parvum and Cryptosporidium hominis. 

In Australia, data from the National Notifiable Diseases Surveillance System (NNDSS) show that cryptosporidiosis outbreaks occur every few years. To better understand the transmission, trends and nature of cryptosporidiosis outbreaks in Western Australia, epidemiological and genomic data from three cryptosporidiosis outbreaks in 2003, 2007 and 2011 were reviewed.

The 2007 outbreak was the largest (n = 607) compared with the outbreaks in 2003 (n = 404) and 2011 (n = 355). All three outbreaks appeared to have occurred predominantly in the urban metropolitan area (Perth), which reported the highest number of case notifications; increases in case notifications were also observed in rural and remote areas. Children aged 0–4 years and non-Aboriginal people comprised the majority of notifications in all outbreaks. However, in the 2003 and 2007 outbreaks, a higher proportion of cases from Aboriginal people was observed in the remote areas. Molecular data were only available for the 2007 (n = 126) and 2011 (n = 42) outbreaks, with C. hominis the main species identified in both outbreaks. Subtyping at the glycoprotein 60 (gp60) locus identified subtype IbA10G2 in 46.3% and 89.5% of C. hominis isolates typed, respectively, in the 2007 and 2011 outbreaks, with the IdA15G1 subtype was identified in 33.3% of C. hominis isolates typed in the 2007 outbreak. The clustering of cases with the IdA15G1 subtype in the remote areas suggests the occurrence of a concurrent outbreak in remote areas during the 2007 outbreak, which primarily affected Aboriginal people.

Both the C. hominis IbA10G2 and IdA15G1 subtypes have been implicated in cryptosporidiosis outbreaks worldwide; its occurrence indicates that the mode of transmission in both the 2007 and 2011 outbreaks was anthroponotic. To better understand the epidemiology, sources and transmission of cryptosporidiosis in Australia, genotyping data should routinely be incorporated into national surveillance programmes.

Petting zoos as a source of shiga-toxin producing E. coli in Austria

Hey Gonzo, they cited us.

Too bad your soccer teams suck, and I don’t care.

But I do care when others cite the gumshoe work we put into our research activities.

And I especially care when every year, I tell our public school or the local shopping mall that petting farms around kids can lead to heartache.

They call me crazy, just like they continue to top salads with raw alfalfa sprouts at Brisbane Private Hospital, despite my protestations.

I do what I can.

These others are microbiological idiots.

There, I’m done.

Despite their general low incidence, Shiga toxin-producing Escherichia (E.) coli (STEC) infections are considered an important public health issue due to the severity of illness that can develop, particularly in young children.

 We report on two Austrian petting zoos, one in Tyrol (2015) and one in Vorarlberg (2016), which were identified as highly likely infection sources of STEC infections. The petting zoo related cases involved a case of hemolytic uremic syndrome (HUS) due to STEC O157:HNM in 2015 and an outbreak of STEC O157:H7 infections affecting five young children and two adults in 2016. The HUS case accounted for 2.8% of the 36 STEC O157:HNM/H7 infections notified in Austria in 2015 (5,9% of 17 HUS cases). The seven cases described for 2016 accounted for 4.0% of the 177 human STEC infections documented for Austria in 2016, and for 19% of the 36 STEC O157:HNM/H7 infections notified that year.

The evaluation of the STEC infections described here clearly underlines the potential of sequence-based typing methods to offer suitable resolutions for public health applications. Furthermore, we give a state-of-the-art mini-review on the risks of petting zoos concerning exposure to the zoonotic hazard STEC and on proper measures of risk-prevention.

Erdozain G, Kukanich K, Chapman B, Powell D. 2012. Observation of public health risk behaviours, risk communication and hand hygiene at Kansas and Missouri petting zoos – 2010-2011. Zoonoses Public Health. 2012 Jul 30. doi: 10.1111/j.1863-2378.2012.01531.x. [Epub ahead of print]

Outbreaks of human illness have been linked to visiting settings with animal contact throughout developed countries. This paper details an observational study of hand hygiene tool availability and recommendations; frequency of risky behavior; and, handwashing attempts by visitors in Kansas (9) and Missouri (4), U.S., petting zoos.

Handwashing signs and hand hygiene stations were available at the exit of animal-contact areas in 10/13 and 8/13 petting zoos respectively. Risky behaviors were observed being performed at all petting zoos by at least one visitor. Frequently observed behaviors were: children (10/13 petting zoos) and adults (9/13 petting zoos) touching hands to face within animal-contact areas; animals licking children’s and adults’ hands (7/13 and 4/13 petting zoos, respectively); and children and adults drinking within animal-contact areas (5/13 petting zoos each). Of 574 visitors observed for hand hygiene when exiting animal-contact areas, 37% (n=214) of individuals attempted some type of hand hygiene, with male adults, female adults, and children attempting at similar rates (32%, 40%, and 37% respectively). Visitors were 4.8x more likely to wash their hands when a staff member was present within or at the exit to the animal-contact area (136/231, 59%) than when no staff member was present (78/343, 23%; p<0.001, OR=4.863, 95% C.I.=3.380-6.998). Visitors at zoos with a fence as a partial barrier to human-animal contact were 2.3x more likely to wash their hands (188/460, 40.9%) than visitors allowed to enter the animals’ yard for contact (26/114, 22.8%; p<0.001, OR= 2.339, 95% CI= 1.454-3.763). Inconsistencies existed in tool availability, signage, and supervision of animal-contact.

Risk communication was poor, with few petting zoos outlining risks associated with animal-contact, or providing recommendations for precautions to be taken to reduce these risks.
