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).
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.
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.

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.

Grower Carol Metcalf said the rows of rotting melons were the result of the listeria outbreak on a rockmelon farm more than 3,500 kilometres away in New South Wales.
Under a new plan released this week, all rockmelon farms in Australia will be inspected and work will be undertaken on each individual farm to ensure that the highest standards are implemented and maintained.
At the time of the outbreak on February this year, the NSW Food Authority speculated that the most likely cause of the listeria outbreak was contaminated soil possibly not being properly washed off the skin of the fruit.
In addition it was thought that a weather event may have increased the listeria bacteria on the product.
But the formal investigation into the cause of the outbreak has not been completed by the NSW Food Authority and therefore the official report on the cause has still not been released.
What is planned is visits to all Australian rockmelon growers and packing sheds to review and audit current practice and critical control points and provide one-on-one food safety consultations with growers, managers and key farm staff.
The development of a melon food safety Best-Practice Guide, was informed by the findings from consultations, feedback from retailers and other key stakeholder groups.
The development of a ‘toolbox’ for grower use including risk assessment templates, training guides, food safety posters and record sheets to support food safety programs — this will be housed on the Australian Melon Association website.
Regional roadshows in key growing regions will highlight the availability and contents of the toolbox and Best Practice Guide.
A helpdesk to provide technical support to growers, packers and other stakeholders will also be developed.
Australian Melon Association industry development manager Dianne Fullelove said the new initiatives would ensure that every rockmelon grower in Australia had the highest level of food safety possible.
“NSW DPI will lead the project and the key is that they will visit every farm and work with every grower to fix any problems or issues.
“We want to make food safety as good as it can be,” Ms Fullelove said.
“This new initiative will make that reputation even stronger and give our growers sure-fire tools to support our product integrity for decades to come.
“This move will put us ahead of the game.”
Food safety isn’t a game, not when your product contributes to the death of seven people and one miscarriage.
Why are melon growers relying on government to visit farms (oh, right, money).
They should hire their own people to be out front on any food safety issue; government is the last source to rely on. And don’t act like this is something new: There have been plenty of outbreaks of Listeria and Salmonella on rockmelon over the years.
(A table of rockmelon-related outbreaks is available here.)
Some basic questions that have yet to be answered:
was the farm prone to flooding and near any livestock operations;
what soil amendments, like manure, were used;
after harvest were the rockmelons placed in a dump tank;
was the water in the dump tank regularly monitored for chlorine levels;
did a proper handwashing program exist at the packing shed;
were conveyor belts cleaned and tested;
did condensation form on the ceiling of the packing shed;
were transportation vehicles properly cooled and monitored;
was the Listeria in whole cantaloupe or pre-cut; and,
was the rockmelon stored at proper temperatures at retail?
Stop waiting for change to happen and take charge, without relying on government: Your growers are still losing money.
Brad Crouch of The Advertiser writes seven people are in hospital and another 14 sick from eating alfalfa sprouts, triggering a SA Health warning to the public not to eat alfalfa sprout products produced by Adelaide business SA Sprouts.
SA Health Chief Medical Officer and Chief Public Health Officer, Professor Paddy Phillips, said there had been 21 confirmed cases of Salmonella havana linked to the sprouts.
“We are advising anyone who has purchased the recalled SA Sprouts alfalfa sprouts products to return them to the place of purchase for a refund, or throw them away,” Prof Phillips said.
“We also want to alert cafes and restaurants to check their suppliers and not serve any SA Sprouts alfalfa sprout products until further notice.
“In cases of salmonella a common food source is not often identified, however a joint investigation between SA Health, local government and Primary Industries and Regions SA (PIRSA) has linked these cases to SA Sprouts alfalfa sprouts.
“We are working closely with the producer and suppliers while we continue to investigate.”
He wrote on the bakery’s Facebook page, “Have been coming to this bakery for years. At least once a fortnight, for a Sunday morning pie and ice coffee with the fam.
“This all stops today untill [sic] I hear that the place has got its s**t together.”
The review went on to list exactly why he was disappointed by his pie and coffee.
“1. Pie wasn’t even warm,” the first point read.
“2. Tasted like it was microwaved than grilled. Had that weird raw pastry taste.
“3. My ice coffee is out of date. Today is the 3rd my ice coffee ran out on first.
“The nutella donuts scored them the second star.”
The customer commented on how cold the pie was, and that his flavoured milk was out of date.
But his review was met with hostility, when the local bakery responded and called him a “w**ker”, a “gutless troll” and a “little b**ch”.
“F***ing keyboard worrier,” the post from Howard Springs Bakery read.
“Does it make you feel like a man to post this bulls**t. Get a life you w**ker.
“Say you been going for years and have 1 bad pie and crack the sads like a little b**ch. If you weren’t satisfied, take it back for a refund or exchange instead of jumping on your phone last a right pr**k.
“Staff make mistakes, its life, it happens, get over it. Let me know where you work and I’ll have the staff member come and review you. Gutless Troll. Not nice is it.”
Mark Donaldson of the Wanneroo Times writes, a Currambine food outlet, which has now shut down, has been fined for a food safety breach after a customer bit into a piece of metal while eating a meal last year.
DS Business Venture, which ran Pastacup at Currambine Central, was due to stand trial in Joondalup Magistrates Court today but changed its plea to guilty.
No one from the business appeared in court to face the charge of “a person must not sell food that is unsuitable”.
The City of Joondalup prosecutor said a customer bought a three cheese ravioli from the store in May, 2017.
The complainant was eating a meal and bit into something hard, damaging a tooth.
Investigators found it was a rivet that had fallen off a cheese grater.
Magistrate Edward de Vries considered it a minor food safety case but said the customer “would have been in some pain biting into a metal rivet”.
He fined the business $3000 plus costs of another $3000.
The prosecutor conceded there was little chance of recovering the fine now the business had shut down.
