Raw is risky: South Korean man, 71, had hand amputated when skin started rotting 12 hours after eating sushi

Zoe Drewett of Metro wrote in August that a man from South Korea became infected with a potentially deadly flesh-eating bacteria which caused painful black ulcers to grow across his skin 12 hours after indulging in the raw seafood. The infection was so bad that he had to have his hand and forearm amputated 25 days later.

The 71-year-old man went to hospital after two days of fever and excruciating pain in his left hand that had developed 12 hours after eating raw seafood Medics drained the blisters before deciding his limb could not be saved because the unnamed man’s skin had started rotting so badly. The pensioner visited doctors in Jeonju, South Korea, after experiencing excruciating pain in his hand for two days. His story, published in the New England Journal of Medicine, took a turn when a blister on the palm of his hand grew to 3.5cm by 4.5cm – approximately the size of a golf ball.

419 sick with Salmonella from raw frozen chicken thingies in Canada since June 2017

Most frozen breaded chicken products available for sale in grocery stores in Canada contain raw chicken that can cause Salmonella illness and therefore pose an increased health risk to Canadians who handle, prepare or consume them.

Such products include chicken nuggets, chicken strips, chicken burgers, popcorn chicken and chicken fries. Canadians need to be aware that even though these products may appear to be cooked, they are not. They need to be handled carefully and cooked properly to an internal temperature of at least 74°C (165°F) before they are safe to eat.

According to the Canada’s Chief Medical Officers of Health, over the past 16 months, federal, provincial and territorial public health partners have identified hundreds of laboratory-confirmed human illnesses associated with frozen raw breaded chicken products contaminated with Salmonella, due at least in part to inadequate cooking or handling. And for every laboratory-confirmed illness reported, we know that there are dozens more unreported illnesses in Canada. During this same period, there have also been food recall warnings issued for seven different frozen raw breaded chicken products.

Despite these warnings and efforts to educate the public on safe food-handling practices, we continue to see hundreds of Salmonella illnesses among Canadians of all ages because of consumption of or exposure to improperly cooked frozen raw breaded chicken products Maybe inform beaucratcs or different techniques.’or PR-types.

We are very pleased that the Government of Canada is working with the food manufacturing industry and food retailers to reduce Salmonella in frozen raw breaded chicken products produced on or after April 1, 2019, to below detectable amounts, thereby reducing the risk of illness for everyone who handles or consumes these types of products. However, until April 1, 2019, and likely for up to a year after this date, frozen raw breaded chicken products containing Salmonella will continue to be in the marketplace and in freezers across the country. 

This is why, collectively, we are stressing the importance of handling and preparing frozen raw breaded chicken products with caution. Always cook your frozen raw breaded chicken products thoroughly according to the package instructions to an internal temperature of at least 74°C (165°F) using a digital food thermometer to ensure that they are safe to eat. Wash your hands before and after handling these products, and wash and sanitize the surfaces, dishes and utensils used to prepare and serve them. Following this advice when handling, cooking or eating these products will help reduce you and your family’s chance of becoming infected with Salmonella.

In 2007, Kansas State researchers developed a novel video capture system to observe the food preparation practices of 41 consumers – 21 primary meal preparers and 20 adolescents – in a mock domestic kitchen using frozen, uncooked, commercially available breaded chicken products. The researchers wanted to determine actual food handling behavior of these two groups in relation to safe food handling practices and instructions provided on product labels. Self-report surveys were used to determine whether differences exist between consumers’ reported food handling practices and observed behavior. 

The research appeared in the November 2009 issue of the British Food Journal. In addition to Jacob and Powell, the authors were: Sarah DeDonder, K-State doctoral student in pathobiology; Brae Surgeoner, Powell’s former graduate student; Benjamin Chapman, an assistant professor at North Carolina State University and Powell’s former graduate student; and Randall Phebus, K-State professor of animal science and industry.

Beyond the discrepancy between adult and adolescent food safety practices, the researchers also found that even when provided with instructions, food preparers don’t follow them. They may not have even seen them or they assume they know what to do. 

“Our results suggest that while labels might contain correct risk-reduction steps, food manufacturers have to make that information as compelling as possible or it will be ignored,” Chapman said.

They also found that observational research using discreet video recording is far more accurate than self-reported surveys. For example, while almost all of the primary meal preparers reported washing hands after every instance in which they touched raw poultry, only half were observed washing hands correctly after handling chicken products in the study.

Powell said that future work will examine the effectiveness of different food safety labels, messages and delivery mechanisms on consumer behavior in their home kitchens.

Abstract:
Purpose – The purpose of the present study was to observe the preparation practices of both adult and young consumers using frozen, uncooked, breaded chicken products, which were previously involved in outbreaks linked to consumer mishandling. The study also sought to observe behaviors of adolescents as home food preparers. Finally, the study aimed to compare food handler behaviors with those prescribed on product labels.
Design/methodology/approach – The study sought, through video observation and self-report surveys, to determine if differences exist between consumers’ intent and actual behavior.
Findings – A survey study of consumer reactions to safe food-handling labels on raw meat and poultry products suggested that instructions for safe handling found on labels had only limited influence on consumer practices. The labels studied by these researchers were found on the packaging of chicken products examined in the current study alongside step-by-step cooking instructions. Observational techniques, as mentioned above, provide a different perception of consumer behaviors.
Originality/value – This paper finds areas that have not been studied in previous observational research and is an excellent addition to existing literature.

Night soil: Kenyans feeding on Sukuma wiki grown in raw sewage

While some city residents have become farmers either by design or default depending on the residential area one resides in, cheap is proving to be life threatening as farmers are now using raw sewage for farming. This means much of the vegetables especially sukuma wiki (kales) on sale in Nairobi are highly contaminated and pose a serious health risk to consumers.

A visit to the sewage collection point in Njiru, Nairobi by Linda Shiundu of TUKO.co.ke revealed the effluence deposited there is always tapped and used for farming by farmers living. The farmers who wished to remain anonymous said instead of waiting for the rains, they would rather take advantage of the 75,000 liters of untreated sewage disposed daily to water their crops. They do so by digging trenches from the deposit site channeling the semi solid human waste into their farms which they use to water the crops and as manure. They mainly grow vegetables like sukuma wiki, spinach and other crops like bananas. Sewage deposited at the sewage collection point around Njiru area is always trapped by farmers living around the collection center and use for planting. The vegetables later on find their way into the market and in to the plates and stomachs of many unsuspecting residents. The vegetables later on find their way into the market.

Despite the health risks posed by the exposed raw sewage including, diarrhea, abdominal pain, vomiting and even death, open food kiosks are also run next to the disposal site. The kiosks are normally flooded with drivers who bring in the hundreds of lorries daily to deposit the sewage.

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.

‘I just bear up to my bewilderness’ Trichinella in undercooked bear meat, Japan, 2016

An outbreak of trichinellosis occurred in Japan in December 2016. All case-patients had eaten undercooked bear meat, from which Trichinella larvae were subsequently isolated. DNA sequencing analysis of the mitochondrial genes cytochrome c-oxidase subunit 1 and internal transcribed spacer 2 confirmed that Trichinella T9 had caused the outbreak.

How produce gets contaminated in the field: A review

Foodborne illness resulting from the consumption of contaminated fresh produce is a common phenomenon and has severe effects on human health together with severe economic and social impacts.

The implications of foodborne diseases associated with fresh produce have urged research into the numerous ways and mechanisms through which pathogens may gain access to produce, thereby compromising microbiological safety.

This review provides a background on the various sources and pathways through which pathogenic bacteria contaminate fresh produce; the survival and proliferation of pathogens on fresh produce while growing and potential methods to reduce microbial contamination before harvest.

Some of the established bacterial contamination sources include contaminated manure, irrigation water, soil, livestock/ wildlife, and numerous factors influence the incidence, fate, transport, survival and proliferation of pathogens in the wide variety of sources where they are found. Once pathogenic bacteria have been introduced into the growing environment, they can colonize and persist on fresh produce using a variety of mechanisms.

Overall, microbiological hazards are significant; therefore, ways to reduce sources of contamination and a deeper understanding of pathogen survival and growth on fresh produce in the field are required to reduce risk to human health and the associated economic consequences.

Use a thermometer: Raw frozen chicken burgers sicken 68 in Canada

Craig Takeuchi of Straight writes several more cases of Salmonella have been reported in an outbreak across Canada linked to a recalled frozen raw chicken product.

The Pubic Health Agency of Canada, the Canadian Food Inspection Agency, Health Canada, and provincial and territorial health partners have been investigating and issued a public notice about the Salmonella Enteritidis outbreak on June 2.   

The Canadian Food Inspection Agency had issued a food recall warning on June 2 for a frozen raw breaded chicken product: No Name brand chicken burgers (1 kilogram) from Loblaw Companies Limited with a best before date of February 6, 2019 (with UPC code 0 60383 16636 6). The product was distributed nationally.

Several affected individuals in the outbreak had reported consuming the product.

As of June 18, there were nine additional cases of illness to increase the total number of infections to 68 individuals. Eight of those cases are in B.C., and the largest number is in Quebec, where there are 23 cases.

So far, 15 people have been hospitalized but no deaths have been reported.

Canadians are advised not to consume the product and to either dispose of it or return it to the store it was purchased from while restaurants are advised not to serve it. Those who do not have the original packaging and are uncertain if it is included in the food recall are advised to throw it out to be safe.

Sprouts still suck: Seven in hospital, 14 more sick with Salmonella from alfalfa sprouts in South Australia

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.”

Raw is risky: Oysters suspected as jury awards couple $6.7 million in Tampa food poisoning

Jonathan Capriel of Tampa Bay reports a jury awarded a couple $6.7 million after they got sick from eating seafood at a Tampa restaurant. The verdict came in May, years after the husband’s illness led to a rare disorder that causes paralysis and nerve damage.

Angel Martinez and his wife Maria Elena Martinez had eaten 10 times earlier at Lobster Haven, 12807 W Hillsborough Ave., when they sat down Dec. 21, 2013, for their usual — two three-pound lobsters and a dozen Bluepoint oysters, according to court records.

The couple declined to comment for this story, as did Lobster Haven owner Daniel Hall.

Attorneys for the couple said the illness was likely caused by the oysters.

“You take a risk when eating raw oysters,” said Brandon Cathey, who represented the Martinezes. “It might get you sick, but you don’t expect it to cause lifelong nerve damage.”

A few hours after the meal, the couple experienced vomiting and diarrhea, according to court records.

Maria Elena Martinez recovered in a few days, but three weeks later, her husband had to be taken by ambulance to Pasco Regional Medical Center after he collapsed on the floor at his home, according to court records.

Doctors transferred him to Tampa General Hospital, where he spent seven days in the intensive care unit, according to court records. He was paralyzed from the waist down for several months and had to learn how to walk again, according to court records.

Martinez’s foodborne illness developed into Guillain-Barre Syndrome, a rare disorder that causes the immune system to attack one’s own body.

He has recovered from the most severe symptoms of the illness but will likely feel long term effects, said his attorney Brent Steinberg.

Lobster Haven admitted it served the couple seafood that poisoned them but denied that it caused Guillain-Barre Syndrome, blaming instead a lamb that Mr. Martinez slaughtered and ate days later.

Lobster Haven’s insurance company offered to settle the case for $20,000 in 2016, Cathey said, but by then Martinez’s medical bills had reached more than $325,000, according to court records.

The restaurant had liability insurance up to $1 million and the Martinez’ likely would have settled for that amount, Cathey said.

“Now this restaurant may go out of business,” he said, “because of the way his insurance company handled this.”

Raw is risky: Squid sperm buries into woman’s tongue

A 63-year-old woman got a nasty shock when tucking into a seafood dinner.

According to Sophie Roberts of the Daily Star, the South Korean patient sought medical attention after she consumed raw squid.

Doctors discovered that her mouth had been inseminated by the creature’s sperm, which had lodged into her tongue and gums.

A Journal of Parasitology report noted that the woman immediately knew something was wrong with the dish.

Even though she spat out the mouthful, she was still affected by the uncooked seafood.

It explained: “As soon as she put a piece into her mouth, she felt like many ‘bugs’ were biting her oral mucosa.

“She experienced severe sharp pain and spat out the entire portion without swallowing.

“Despite that, she could feel many small squirming white bug-like organisms penetrating her.”

The squid sperm acted as it would during reproduction, leading to it implanting itself into the patient’s mouth.

After seeking medical attention, the woman was believed to make a full recovery.

While this case may seem very out of the ordinary, it isn’t the first time it has happened.

In 2011, a 21-year-old woman fell victim to a similar problem after consuming the sexual organs of a raw squid.

Pathology International reported that she also suffered issues with her gums and tongue.

The study warned: “Consumption of a squid with sperm bags and an active ejaculatory apparatus can lead to unintended ejection of the sperm bag and injury to the oral mucosa.”

This whole process is actually autonomous, meaning that the squid’s sex organ is prone to firing off without any conscious decision by the squid, according to a study in the journal Zoomorphology.
