Some of its most popular cheeses, including its 200g camembert and brie are being recalled. Dixie Sulda and Jessica Galletly of Adelaide Now report the SA company said there was no evidence the form of E.coli found was dangerous but it was recalling them as a precaution.
The cheeses are available from Coles and independent retailers in SA, Queensland, Victoria and WA. In NSW they also sell at Woolies and in Tasmania they are sold at independent retailers.
Udder Delights chef executive Sheree Sullivan said the team was “devastated” after small levels of the bacteria were found in some of the company’s white mould 200g cheeses.
“It is with a very heavy heart that Udder Delights is doing its first voluntary recall since we began 20 years ago,” Ms Sullivan said.
“The whole team is devastated, because we all just work so hard to create a really high quality product.
“You always learn some of your best lessons through disasters, and I never really understood what a voluntary recall was. It means you have a choice – do you want to recall or not? We decided as a business we wanted to be 100 per cent sure it was safe.
“It was great SA Health and Dairysafe confirmed it wasn’t a dangerous bacteria, which can sometimes be a little bit of sunshine in a dark cloud.”
Ms Sullivan would not speculate on what caused the contamination, but said they were working with SA Health and their quality assurance team to quickly resolve the issue.
AIMS: The aim of this study was to evaluate the microbiological quality of commercially prepared ready-to-eat (RTE) sushi by enumerating aerobic mesophilic bacteria (AMB) and thermotolerant coliforms (TC) and detecting Escherichia coli and Salmonella ssp. An isolate was identified as E. coli O157:H7 which was evaluated for its virulence and antimicrobial resistance profiling as well as its ability to form biofilms on stainless steel.
METHODS AND RESULTS: There were four sampling events in seven establishments, totalling 28 pools of sushi samples. Mean AMB counts ranged between 5·2 and 7·7 log CFU per gram. The enumeration of TC varied between 2·1 and 2·7 log MPN per gram. Salmonella ssp. were not detected, and one sample was positive for E. coli and was identified as E. coli O157:H7. To the best of our knowledge, this is the first report of E. coli O157:H7 in sushi samples in the world literature. This isolate presented virulence genes stx1, stx2, eae and hlyA. It was also susceptible to 14 antimicrobials tested and had the ability to form biofilms on stainless steel.
CONCLUSIONS: There is a need to improve the good hygiene practices adopted in establishments selling sushi in the city of Pelotas, Brazil. In addition, the isolated E. coli O157:H7 carries a range of important virulence genes being a potential risk to consumer health, as sushi is a RTE food. This isolate also presents biofilm formation ability, therefore, may trigger a constant source of contamination in the production line of this food.
SIGNIFICANCE AND IMPACT OF THE STUDY: The increase in the consumption of sushi worldwide attracts attention regarding the microbiological point of view, since it is a ready-to-eat food. To our knowledge, this was the first time that E. coli O157:H7 was identified in sushi samples.
First report of Escherichia coli O157:H7 in ready-to-eat sushi
I have so many Larry stories that I’d probably get sued now that he’s a big shot.
But when I was teaching him and Kevin, about 1995 (I may have noticed Chapman joined my lab about 1999, it’s all a purple haze, but I got those 70 peer-reviewed papers out and made full-professor) so here’s Larry, now that he’s returned to Guelph (that’s in Ontario, Canada) and maybe you have a chat with Malcolm, see about getting my $750,000 returned and we can do some fun research.
Despite appearances, experts say a recent rise in major recalls is not a sign of food supply problems, but the result of a more active investigative body and better testing tools — though they add more can be done.
“This is proof that the system is working well,” said Lawrence Goodridge, a professor focusing on food safety at The University of Guelph, speaking about the recent meat recall.
Yet, he believes that “in Canada, we have to get to a place where we can actually stop the food from going to retail in the first place.”
Since Sept. 20, a investigation by the Canadian Food Inspection Agency into possible E. coli 0157:H7 contamination in some beef and veal products sold by Ryding-Regency Meat Packers Ltd. and St. Ann’s Foods Inc. has led to the recall of nearly 700 products.
The CFIA suspended the Canadian food safety license for St. Ann’s meat-processing plant, as well as Ryding-Regency’s slaughter and processing plant, both in Toronto, in late September.
No illnesses have been reported in association with the products, according to the CFIA, but symptoms of sickness can include nausea, vomiting, abdominal cramps.
Emma Broadhurst was six months pregnant when she flew out to Turkey with friends for a 7-night stay at the Crystal Sunset Luxury Resort and Spa, east of the city of Antayla, at the start of September.
But, according to Andy Rudd of The Mirror, within days of arriving she fell unwell suffering from chronic diarrhea and became dehydrated and lost weight.
Just over 24 hours later her best friend’s seven-year-old son, Kailan, also fell ill with diarrhea and on their return to the UK his mum, Emma McComb, fell ill and Kailan was left ‘screaming in agony’ and projectile vomiting.
All three, who shared a room while on holiday, were then diagnosed with salmonella poisoning after stool samples were sent for testing by their local GP, claims Emma.
The friends stayed in the same hotel where two-year-old Allie Birchall and her family holidayed before little Allie was taken ill before passing away having contracted E. coli.
All members of her family, from Wigan, Greater Manchester, suffered from gastric symptoms including stomach cramps and diarrhoea during their 10-day stay with Jet 2.
Allie’s condition became so severe she was rushed to hospital after the family returned to the UK.
Her parents had to make the heartbreaking decision to switch off her life support on August 3.
Dr. Janice Fitzgerald said some of the cases are connected to an advisory issued by Memorial University last week, saying Eastern Health was investigating reports of students experiencing gastrointestinal illness.
The university said Wednesday that test results indicated one student living in residence “may have contracted the E. coli bacteria” and 21 students had reported similar symptoms.
Fitzgerald said it’s too early in the investigation to determine a cause of the outbreak.
Two abstracts attempt to provide guidance to these important questions to reduce the toll of STEC.
FAO and WHO conclude shiga toxin-producing Escherichia coli (STEC) infections are a substantial public health issue worldwide, causing more than 1 million illnesses, 128 deaths and nearly 13 000 Disability-Adjusted Life Years (DALYs) annually.
To appropriately target interventions to prevent STEC infections transmitted through food, it is important to determine the specific types of foods leading to these illnesses.
An analysis of data from STEC foodborne outbreak investigations reported globally, and a systematic review and meta-analysis of case-control studies of sporadic STEC infections published for all dates and locations, were conducted. A total of 957 STEC outbreaks from 27 different countries were included in the analysis.
Overall, outbreak data identified that 16% (95% UI, 2-17%) of outbreaks were attributed to beef, 15% (95% UI, 2-15%) to produce (fruits and vegetables) and 6% (95% UI, 1-6%) to dairy products. The food sources involved in 57% of all outbreaks could not be identified. The attribution proportions were calculated by WHO region and the attribution of specific food commodities varied between geographic regions.
In the European and American sub-regions of the WHO, the primary sources of outbreaks were beef and produce (fruits and vegetables). In contrast, produce (fruits and vegetables) and dairy were identified as the primary sources of STEC outbreaks in the WHO Western Pacific sub-region.
The systematic search of the literature identified useable data from 21 publications of case-control studies of sporadic STEC infections. The results of the meta-analysis identified, overall, beef and meat-unspecified as significant risk factors for STEC infection. Geographic region contributed to significant sources of heterogeneity. Generally, empirical data were particularly sparse for certain regions.
Care must be taken in extrapolating data from these regions to other regions for which there are no data. Nevertheless, results from both approaches are complementary, and support the conclusion of beef products being an important source of STEC infections. Prioritizing interventions for control on beef supply chains may provide the largest return on investment when implementing strategies for STEC control.
Second up, in 2016, we reviewed preventive control measures for secondary transmission of Shiga-toxin producing Escherichia coli (STEC) in humans in European Union (EU)/European Free Trade Association (EEA) countries to inform the revision of the respective Norwegian guidelines which at that time did not accommodate for the varying pathogenic potential of STEC.
We interviewed public health experts from EU/EEA institutes, using a semi-structured questionnaire. We revised the Norwegian guidelines using a risk-based approach informed by the new scientific evidence on risk factors for HUS and the survey results.
All 13 (42%) participating countries tested STEC for Shiga toxin (stx) 1, stx2 and eae (encoding intimin). Five countries differentiated their control measures based on clinical and/or microbiological case characteristics, but only Denmark based their measures on routinely conducted stx subtyping. In all countries, but Norway, clearance was obtained with ⩽3 negative STEC specimens. After this review, Norway revised the STEC guidelines and recommended only follow-up of cases infected with high-virulent STEC (determined by microbiological and clinical information); clearance is obtained with three negative specimens.
Implementation of the revised Norwegian guidelines will lead to a decrease of STEC cases needing follow-up and clearance, and will reduce the burden of unnecessary public health measures and the socioeconomic impact on cases. This review of guidelines could assist other countries in adapting their STEC control measures.

Allie Birchall came down with the severe illness after returning to the UK following a stay at a luxury resort east of the coastal city of Antayla.
Her family were forced to turn off Allie’s life support machine just two weeks after their holiday because of complications caused by the illness.
The family had travelled to Turkey with tour operator Jet2 Holidays on 12 July and said they had concerns about the hygeine of the Turkish resort.
Katie Dawson, Allie’s mother, said her daughter did not start getting ill until five days after getting back to their home in Atherton, Greater Manchester.
According to Ms Dawson, Allie began suffering with stomach cramps, diarrhoea, loss of appetite and lethargy before being admitted to Royal Bolton Hospital on July 30.
The hospital confirmed Allie had contracted Shiga-Toxin producing E.Coli (STEC), which later led to her developing deadly Haemolytic Uraemic Syndrome (HUS) – a life-threatening complication related to the poisoning.
Allie was moved to the Manchester Royal Infirmary and put in an induced coma on August 1.
An MRI scan was carried out, which revealed that she had sustained severe brain trauma and damage. Katie had to make the difficult decision to terminate Allie’s life support following the advice from doctors.
“While nothing will bring her back, we need to know what caused her illness and if anything could have been done to prevent it.
The family have now instructed specialist international serious injury lawyers, Irwin Mitchell, to investigate what happened.
Public Health England is also currently investigating the matter, and an inquest has been opened to examine the circumstances surrounding Allie’s death.
To date, disease doctors have identified 11 cases of E. coli 0157 among Minnesotans who were at the State Fair between Aug. 25 and Sept. 2. All of them fell ill between Aug. 29 and Sept. 6.
Ages of those sickened range from 2 to 43 years old. Six of the cases required the patient to be hospitalized, including one person developing hemolytic uremic syndrome, which the MDH says is a potentially fatal complication.
One person is still in a hospital being treated.
Investigators are working to determine the source of the outbreak, with evidence so far indicating that it most likely began with contact with livestock.
Most of the 11 patients visited the Miracle of Birth exhibit and made physical contact with calves, goats, sheep or piglets, but others suffering from the E. coli strain did not make direct contact with animals, leading the MDH to consider the possibility that those people made contact with contaminated surfaces.
“This serves as a strong reminder to always wash your hands after being around livestock and their enclosures,” the MDH says.
Fortunately, there is “little chance” of ongoing exposure to the strain since the fair has ended.
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.
Observation of public health risk behaviors, risk communication and hand hygiene at Kansas and Missouri petting zoos – 2010-2011Outbreaks 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.
