“But have you undercooked chicken sausage (unintentionally) and then served it to your bf and then he got superrrrr sick and you thought it was covid and you got tested twice but nah you just fed him salmonella? He should break up with me. I would,” he tweeted.
When told that Austin needs to take his phone away, Kevin then added: “He’s asleep because I poisoned him!”
He then tweeted “Omg” when he realized that Austin hilariously changed his profile bio to: “I left Twitter many years ago. I’m back on now to monitor my thirsty boyfriend, Kevin Mchale, who ‘accidentally’ gave me salmonella 5 days ago.”
Use a tip-sensitive digital thermometer. Any fans of McHale should mail him one (if the U.S. Postal Service still exists).
The New York Times followed up on the chicken study and how to tell if it’s done that I wrote about last week with a meandering story about color, texture, and stupidly recommends using pop-up thermometers.
Me and the U.S. Department of Agriculture and many others have been saying the same thing for over 20 years: Use a fucking tip-sensitive digital thermometer.
About one third of foodborne illness outbreaks in Europe are acquired in the home and eating undercooked poultry is among consumption practices associated with illness. The aim of this study was to investigate whether actual and recommended practices for monitoring chicken doneness are safe.
Seventy-five European households from five European countries were interviewed and videoed while cooking chicken in their private kitchens, including young single men, families with infants/in pregnancy and elderly over seventy years. A cross-national web-survey collected cooking practices for chicken from 3969 households. In a laboratory kitchen, chicken breast fillets were injected with cocktails of Salmonella and Campylobacter and cooked to core temperatures between 55 and 70°C. Microbial survival in the core and surface of the meat were determined. In a parallel experiment, core colour, colour of juice and texture were recorded. Finally, a range of cooking thermometers from the consumer market were evaluated.
The field study identified nine practical approaches for deciding if the chicken was properly cooked. Among these, checking the colour of the meat was commonly used and perceived as a way of mitigating risks among the consumers. Meanwhile, chicken was perceived as hedonically vulnerable to long cooking time. The quantitative survey revealed that households prevalently check cooking status from the inside colour (49.6%) and/or inside texture (39.2%) of the meat. Young men rely more often on the outside colour of the meat (34.7%) and less often on the juices (16.5%) than the elderly (>65 years old; 25.8% and 24.6%, respectively). The lab study showed that colour change of chicken meat happened below 60°C, corresponding to less than 3 log reduction of Salmonella and Campylobacter. At a core temperature of 70°C, pathogens survived on the fillet surface not in contact with the frying pan. No correlation between meat texture and microbial inactivation was found. A minority of respondents used a food thermometer, and a challenge with cooking thermometers for home use was long response time. In conclusion, the recommendations from the authorities on monitoring doneness of chicken and current consumer practices do not ensure reduction of pathogens to safe levels. For the domestic cook, determining doneness is both a question of avoiding potential harm and achieving a pleasurable meal. It is discussed how lack of an easy “rule-of-thumb” or tools to check safe cooking at consumer level, as well as national differences in contamination levels, food culture and economy make it difficult to develop international recommendations that are both safe and easily implemented.
Cooking chicken at home: common or recommended approaches to judge doneness may not assure sufficient inactivation of pathogens, 29 April 2020
I used to use these semi-disposable thermometers in my old-school fridge, but when we bought our Brisbane house we bought a new fridge which displays the fridge and freezer temps continuously (although I should check on how to validate).
The fridge also has an ice and water dispenser, which I used to have but lost in the divorce or move(s), it’s all a blur now.
A transdisciplinary observational study, coupled with a web-based survey, was conducted to investigate refrigerated storage of food, in five European countries.
The investigated consumer groups in this study were: young families with small children and/or pregnant women, elderly people, persons with an immunodeficient system, and young single men.
The refrigerator temperature was monitored for approximately two weeks using a temperature data logger. Variables such as country, income, age of refrigerators, education, living area, refrigerator loading practices had no significant effect (p > 0.05) on the overall average fridge temperature, whereas consumers’ practices showed a significant influence (p < 0.05) on registered temperature values.
Compared to temperatures inside the fridges belonging to young families and young single men group, the temperatures inside refrigerators belonging to elderly was in the temperature danger zone (5–63 °C). The lowest temperatures were recorded in UK consumers’ refrigerators, whereas the highest were in French households. Presence of Listeria monocytogenes was confirmed in three refrigerators out of 53 sampled (two in Romania and one in Portugal).
The most vulnerable category to food safety risks is represented by elderly persons with low education, unaware of safe refrigeration practices and the actual temperature their fridges are running.

Alexandria Hein of Fox News reports a 43-year-old man in China who was suffering from seizures and loss of consciousness went to the doctor after his symptoms persisted for several weeks, only to discover that he had hundreds of tapeworms in his brain and chest, reports say.
The patient, identified as Zhu Zhongfa, allegedly had eaten undercooked pork, which was contaminated with Taenia solium, a parasitic tapeworm.
“Different patients respond [differently] to the infection depending on where the parasites occupy,” Dr. Huang Jianrong, Zhongfa’s doctor at Affiliated Hospital of Zhejiang University School of Medicine, told AsiaWire. “In this case, he had seizures and lost consciousness, but others with cysts in their lungs might cough a lot.”
Jianrong explained that the larvae entered Zhongfa’s body through the digestive system and traveled upward through his bloodstream. He was officially diagnosed with cysticercosis and neurocysticercosis, and given an antiparasitic drug and other medications to protect his organs from further damage, according to AsiaWire.
Jianrong said his patient is doing well after one week, but the long-term effects from the massive infestation are unclear.
The Centers for Disease Control and Prevention (CDC) recommends cooking meat at a safe temperature and using a food thermometer in an effort to avoid taeniasis. Humans are the only hosts for Taenia tapeworms, and pass tapeworm segments and eggs in feces which contaminate the soil in areas where sanitation is poor. The eggs survive in a moist environment for days to months, and cows and pigs become infected after feeding in the contaminated areas.
Once inside the animal, the eggs hatch in the intestine and migrate to the muscle where it develops into cysticerci, which can survive for several years. This infects humans when they eat contaminated raw or undercooked beef or pork, according to the CDC.
The Food Standards Agency (FSA) has published the Year 4 report for the UK retail chicken survey which took place between August 2017 and July 2018. Samples were collected every quarter but after the first quarter only minor retailers were tested. The UK’s top nine retailers have carried out their own sampling since September 2017.
The report found that high level campylobacter contamination in UK chickens has decreased considerably, but remains high in smaller retailers, independents and butchers.
Rebecca Sudworth, Director of Policy at the Food Standards Agency, said:
“Retailers have achieved significant reductions in levels of campylobacter contamination since the retail chicken survey began in 2014. The FSA will continue to engage with industry and particularly smaller retailers, butchers and independents to build on this progress.” …
Make sure chicken is cooked thoroughly and steaming hot all the way through before serving. Cut into the thickest part of the meat and check that it is steaming hot with no pink meat and that the juices run clear.
Use a tip-sensitive digital thermometer and stick it in.
“We see that celebrity chefs simply rely on time estimates in their recipes or cut through the meat to show there is no blood or pink. That doesn’t always mean the food is safe, however,” says Yaohua “Betty” Feng, an assistant professor of food science at Purdue. “That affects the behaviors of home cooks and professional cooks. If their role models aren’t using thermometers, why should they? But if chefs preparing food on television or social media would include the use of a thermometer to ensure the food is thoroughly cooked, it would have an impact on their viewers.”
Feng worked with University of California’s Christine M. Bruhn to analyze 85 studies from over two decades to understand knowledge, attitudes, and behaviors associated with thermometer use. Despite it being considered a best practice in home and professional kitchens, thermometer use is low.
In one study, two-thirds of people reported owning a meat thermometer, but less than 20 percent used it all the time to check the temperature of chicken, and less than 10 percent used it all the time for hamburgers. About half of consumers say that thermometers aren’t necessary to check the doneness of egg or meat dishes.
Feng also noted that many people are unsure which type of thermometer to buy or how to correctly use them, including where to place the thermometer in the food, the correct endpoint temperatures, proper temperature calibration for the thermometer, and proper cleaning and sanitation. About 95 percent of people in one study did not clean their thermometers after use.
The U.S. Department of Agriculture National Institute of Food and Agriculture’s Agriculture and Food Research Initiative supported this research. The results were published in the Journal of Food Protection in January 2019.
I take pride in my Birmingham and Newport, Wales roots, as well as a lot of Ontario (that’s in Canada) but the UK government’s continued insistence that food be cooked to piping hot is not only unscientific, but just stupid.
This paper sounds nice, but will have no effect.
Chapman, I never got those Comarks, and need about 100 so I can keep improving food safety, one tip-sensitive digital thermometer at a time.
Improper cooking of meat contributes to many foodborne illnesses worldwide. The use of meat thermometers during cooking is recommended by food safety authorities in North America, but not yet in Europe. This scoping review investigated meat thermometer usage trends, consumers’ barriers and facilitators, and usage-enhancing interventions, with the aim of informing potential policy changes as necessary towards enhancing meat thermometers usage.
The study revealed that Europe is far behind North America in meat thermometer research and consumer use. The study results highlighted the increased compliance among mid-aged and higher socio-economic consumer groups. A considerable percentage of people do not use a meat thermometer, despite owning one and knowing its importance.
Barriers to meat thermometer usage among consumers included: cooking habits, non-practicality, and the influence of society and media, whereas responsibility to dependents and enhancing meat quality were strong facilitators. Intervention studies showed that knowledge gain does not necessarily translate to behavior change, unless consumers’ barriers and facilitators are addressed; hence behavioral theory-based interventions were most effective. The review concludes with recommendations for food safety authorities, starting with filling the research gap to understand consumers’ attitudes and behaviors, followed by implementation and scaling-up of evidence-based interventions, associated with cost-effectiveness studies.
Is scoping now a cool word?

The testing was carried out on around 600 samples of lamb, beef, pork, and chicken of both Icelandic and foreign origin between March and December 2018. The purpose of the testing was to determine the prevalence of pathogenic micro-organisms in products when they reach the consumer, and for this reason the samples were taken from shops.
Campylobacter and salmonella were not detected in pork or chicken samples, with the exception of a single sample of pork from Spain. MAST attributes this to improved preventative measures in slaughterhouses.
MAST points to several ways consumers can reduce the risk of infection from salmonella, campylobacter, and E. coli, including cooking meat all the way through and taking care to avoid cross-contamination. Most E. coli is found on the surface of meat, and therefore is killed by frying or grilling, but when meat is ground, the bacteria is distributed throughout. Therefore, hamburgers and other types of ground meat should be cooked through.
“Insanity is doing the same thing over and over again and expecting different results.”
That famous quote, often wrongly ascribed to Albert Einstein, is believed to have originated with Narcotics Anonymous in 1981 (the same year I began university).
In addition to helping raise five daughters, providing endless relationship entertainment to the folks I played pick-up hockey with back in Guelph (that’s pre-Amy, who is playing pick-up as I write this), helping teach lots of kids how to skate, influencing lotsa students (good and bad, not much in-between), pissing off lotsa bureaucrats and industry types, publishing lots of peer-reviewed stuff that still gets cited daily and almost 15,000 barfblog.com posts, I did news.
Food Safety Network news, long before wannabes.
For 26 years I’ve done news.
And always referenced the evidence, or lack thereof.
Until others do the same, they’re just plagiarists.
I combined my background in molecular biology with some journalism experience, and I carved out a path in food safety.
The vision I always had for food safety information, all those years ago, was what I heard about daily – and often directly: How the hell was I supposed to know?
We mined the world (I used Compuserve to get access to the AP wires and others back in the days before Google, when the U.S. Centers for Disease Control’s MMWR would take six months to arrive by mail, when those who needed to know should have had the information as soon as possible).
I am intensely loyal to the kids, er, students, that flourished and maybe we’ll write a book; or maybe not.
I did my best, even when my best wasn’t good enough.
I still love it – I haven’t been paid in over two years — but someone else should be in charge.
I have early-onset dementia, I have other health issues, so rather than submit any more family members to, I’ve got to do news, I am going to step away while I can.
Of the 15,287 barfblog.com posts, I authored (or cut and paste) 13,070 since 2005. That’s 86 per cent, or an ice hockey goalie save percentage of .8549, which isn’t great (should be over .91) but doesn’t exactly suck, because this isn’t hockey.
It’s something different.
And time for me to do something different.
I may still write, maybe about food safety, maybe about other things, maybe about the probability of monkeys flying out of my butt.
But for now, I’ve got other priorities.
Ben can figure out what to do and what he wants to do.
It’s been an honor and a privilege to share your computer screens, maybe even your brain space, and improve food safety, one tip-sensitive digital thermometer, one less serving of raw sprouts, and one calling out of bullshit advice, at a time.
