Australian politicians decided to be good politicians, not leaders – because pioneers get arrows in their back – and threw the issue of same-sex marriage to a public mail-in vote. The yes side won by a 2:1 margin, thereby undermining the foundation of Western society (or so some say).
I say, who cares, let same sex people enjoy the benefits and grief of marriage like the rest of us.
Australian food safety week is Nov. 11-18, 2017.
The organizers have been to my church, and the theme is not hockey, but, “Is it done yet? Use a thermometer for great food, cooked safely every time.”
Stick it in.
The theme last year was“Raw and risky.”
These PR thingies are increasingly meaningless.
Chapman is coming over in Jan. or so, once our renovations are done.
Bring another batch of thermometers, buddy.
If a group wants to promote thermometer use, give them away.
According to a self-reported bullshit survey, 70% of Australians don’t know that 75°C is the safe cooking temperature for high-risk foods such as hamburgers, sausages and poultry. 75% of Australians surveyed also reported that there wasn’t a meat thermometer in their household and only 44% of those with a thermometer reported using is over the previous month.
The U.S. Centers for Disease Control reports that on July 13, 2016, Clark County (Washington) Public Health (CCPH) received a report of diarrheal illness in four of seven members of a single party who dined at a local restaurant on July 6, 2016. The report was received through an online/telephone system for reporting food service–associated illness complaints. Members of the five households in the party reported that their only shared exposure was the restaurant meal. CCPH ordered closure of the restaurant kitchen on July 13, 2016, and began an investigation to identify the source of diarrheal illness and implement additional control measures.
CCPH defined a probable case of restaurant-associated illness as diarrhea lasting >2 days in any restaurant guest or staff member with illness onset from July 1, 2016, to July 23, 2016. After Campylobacter jejuni was cultured from stool specimens submitted by three ill members of the dining party, a confirmed case was defined as culture evidence of C. jejuni infection in any restaurant guest or staff member with onset of diarrheal illness during the same period. Five cases (three confirmed and two probable) were identified, four in restaurant guests and one in a food worker; patient age ranged from 27–46 years; three patients were female.
CCPH conducted a case-control study involving 28 menu items, using 14 non-ill dining companions and restaurant staff members as controls. Consumption of two menu items, chicken liver mousse (odds ratio [OR] = 36.1, 95% confidence interval [CI] = 1.58–828.9), and grilled romaine hearts (OR = 18, 95% CI = 1.19–271.5) were associated with case status. Because of the higher odds ratio of chicken liver mousse and previous Campylobacter outbreaks associated with chicken livers (1,2), the investigation focused on the mousse.
During an inspection on July 15, the sous-chef solely responsible for preparing the chicken liver mousse demonstrated preparation to the CCPH food safety inspector, who observed that the sous-chef used the appearance of the livers alone to determine whether they were fully cooked. Final internal cook temperature of the largest liver measured by the inspector was <130°F (54°C), below the minimum 165°F (74°C) internal temperature deemed necessary by the Food and Drug Administration to eliminate food safety hazards (3). Because raw chicken parts are not required to be free of Campylobacter (4), and the bacteria might be present on the surface of 77% of retail chicken livers (5), CCPH immediately addressed undercooking of the livers.
One patient stool specimen isolate was available for typing by pulsed-field gel electrophoresis (PFGE). The PFGE pattern from this isolate was indistinguishable from those obtained from two chicken liver samples collected in a 2014 campylobacteriosis outbreak in Oregon (1). Chicken livers associated with both the 2014 outbreak and with this outbreak were supplied by the same company. Chicken livers from the lot served at the restaurant on the day of the implicated meal were no longer available; therefore, the U.S. Department of Agriculture could not pursue testing of chicken liver samples.
Among published C. jejuni outbreaks associated with undercooked chicken livers, this outbreak report is the second from the Pacific Northwest (1), and the first in the United States initially reported through an illness complaint system. Because CCPH does not actively investigate Campylobacter cases in persons aged >5 years, and because Campylobacter PFGE is not routinely conducted in Washington, this outbreak would have likely gone undetected if not for the illness complaint system, demonstrating the value of illness complaint investigations to identify outbreaks and mitigate public health risks.
If you are eating leftover pork chops that have not been cooked well-done, you’re putting yourself at risk for Salmonella and Listeria exposure. While many individuals prefer to consume their pork medium, a new study published in Risk Analysis: An International Journal revealed that cooking pork chops to an acceptable temperature does not completely eliminate pathogens, providing these cells with the opportunity to multiply during storage and harm consumers.
It is generally believed that when meat is heat treated to 70 degrees Celsius for two minutes, a one million cell reduction of E. coli, Salmonella, and Listeria is achieved and thus the meat is free of pathogens and safe to eat. However, a report by the European Food Safety Authority revealed that more than 57 percent of Salmonella outbreaks in 2014 were in the household/kitchen, and 13 percent were associated with inadequate heat treatment.
“The results of this study can be combined with dose response models and included in guidelines for consumers on practices to be followed to manage cooking of pork meat at home,” says Alessandra De Cesare, PhD, lead author and professor at the University of Bologna.
In order to assess the pathogen levels in cooked pork, the researchers, from the University of Bologna, the Institute of Food Engineering for Development and the Istituto Zooprofilattico delle Venezie, tested 160 packs of loin chop. The samples were experimentally contaminated with 10 million cells of L. monocytogenes and Salmonella to assess the reduction in pathogens after cooking, in accordance with the Food Safety and Inspection Service (FSIS) and British Retail Consortium (BRC) specifications (ensuring a reduction of at least 100,000 and 1,000,000 cells, respectively). The samples were contaminated on the surface, to mimic contamination via slaughter and cutting.
The samples were divided into groups to be cooked either on gas with a non-stick pan or in a static oven. In each setting, the pork chops were cooked to rare, medium, and well-done. For each cooking combination, 40 repetitions were performed for a total of 240 cooking tests.
The researchers also interviewed 40 individuals between the ages of 20 and 60 to determine household consumer habits regarding doneness preferences. Prior published research was referenced to define meat storage practices and the probability that consumers store their leftovers at room temperature, in the refrigerator or discard them immediately. Growth rate data for the pathogens at each temperature were obtained using the software tool ComBase.
The only cooking treatment able to completely inactivate the pathogens was oven well-done, which achieved a reduction between one and 10 million cells. Statistical analyses of the data showed significant differences related to level of cooking and cooking procedure. However, the researchers explained that factors such as moisture, water activity, fat levels, salts, carbohydrates, pH, and proteins can impact the cooking treatment and effectiveness and, as a consequence, on bacteria survival. These results emphasize the needs to consider the form of pork (such as whole muscle versus ground) being cooked, in addition to the final temperature necessary to inactivate pathogens.
The results show that a reduction between one and 10 million of pathogen cells was reached when applying all of the tested cooking treatments, with product temperatures always reaching 73.6 degrees Celsius or greater. However, according to the simulation results using the obtained cell growth rates, the few surviving cells can multiply during storage in both the refrigerator and at room temperature, reaching concentrations dangerous for both vulnerable and regular consumers.
After storing leftovers, there was a probability for the concentration of pathogens to reach 10 cells ranging between 0.031 and 0.059 for all combinations except oven well-done. Overall, the mean level of exposure to Listeria and Salmonella at the time of consumption was one cell for each gram of meat. The results obtained from this study can be implemented in guidelines for consumers on practices to follow in order to manage cooking pork meat at home.
Color is still a lousy indicator of whether food is safe, but if Clinton High School wanted to make a case, they would provide internal temperature logs.
For two days a Clinton mother says her children sent her pictures of the food being served in the school cafeteria at lunch. She says it appears to be undercooked chicken.
“I don’t want my child sick from food poisoning,” says Kathleen Page, mother of two teens at Clinton High School.
” It was so obviously raw,” says her son, Jonathan Carter, a junior at the school. “You could see pink in it. I’d cut it open with my fork and it’d be more red on the inside.”
Page called the school and was transferred to the cafeteria. “I started to ask her questions and she told me it was none of my business and hung up.”
She also called the Health Department and they told her this wasn’t the first complaint they’d gotten about the school lunches.
Clinton School District Superintendent, Andrew Vining, released a statement regarding the issue.
“The Clinton School District strives to serve our students and staff a variety of meals that are healthy, nutritious, and appealing. The photos that have been circulated do not appear that way. This concerns us and we have taken steps to resolve the matter to ensure our students are provided with the bestmeals possible.
“There were also photos that were circulated regarding apparent raw pork; to clarify, no pork was served.
“The chicken fajita meat which was pictured was Tyson, fully cooked and prepackaged. None of our staff or students have reported becoming ill after eating chicken from our cafeteria. In the event someone does get sick, they need to notify my office and go to their doctor to see if symptoms were due to food-borne illness.
“We regret this has happened and we will continue to put the health of our students first in all things.”
The UK Food Standards Agency advises that poultry should be cooked thoroughly by ensuring it is steaming hot all the way through….NOPE. Use a thermometer and verify that the internal temperature has reached a minimum of 74C (165F). Stop guessing.
Following an article in The Mirror (9 September) which suggests that some people believe that raw chicken dishes are safe to eat, we are reiterating our advice not to eat raw chicken. Raw chicken is not safe to eat – it could lead to food poisoning. Chicken should always be cooked thoroughly so that it is steaming hot all the way through before serving. To check, cut into the thickest part of the meat and ensure that it is steaming hot with no pink meat and that the juices run clear. The article states that ‘if birds have been free range, kept in quality conditions, and processed in a clean environment, there’s not so much to worry about’; but this is not the case. All raw chicken is unsafe to eat, regardless of the conditions that the birds have been kept in. Consuming raw chicken can lead to illness from campylobacter, salmonella and E coli. Symptoms include abdominal pain, diarrhoea, vomiting and fever. In some cases, these bugs can lead to serious conditions.
The U.S. Centers for Disease Control reports in September 2016, the Connecticut Department of Public Health was notified of a cluster of gastrointestinal illnesses among persons who shared a catered lunch.
The Connecticut Department of Public Health worked with the local health department to investigate the outbreak and recommend control measures. Information about symptoms and foods eaten was gathered using an online survey. A case was defined as the onset of abdominal pain or diarrhea in a lunch attendee <24 hours after the lunch. Risk ratios (RRs), 95% confidence intervals (CIs), and Fisher’s exact p-values were calculated for all food and beverages consumed. Associations of food exposures with illness were considered statistically significant at p<0.05. Among approximately 50 attendees, 30 (60%) completed the survey; 19 (63%) respondents met the case definition. The majority of commonly reported symptoms included diarrhea (17 of 18), abdominal pain (15 of 16), and headache (7 of 15).
The median interval from lunch to illness onset was 5.3 hours (range = 0.4–15.5 hours) for any symptom and 7 hours (range = 2.5–13 hours) for diarrhea. Analysis of food exposures reported by 16 ill and 10 well respondents (four respondents did not provide food exposure information) found illness to be associated with the beef dish (RR = undefined; CI = 1.06–∞; p = 0.046) (Table). All 16 ill respondents reported eating the beef. Coffee was also associated with illness; however, all 13 coffee drinkers who became ill also ate the beef. Eating cake approached significance (p = 0.051); all 10 cake eaters who became ill also ate the beef.The caterer had begun preparing all dishes the day before the lunch. Meats were partially cooked and then marinated in the refrigerator overnight. In the morning, they were sautéed 2 hours before lunch. Inspection of the facility found the limited refrigerator space to be full of stacked containers that were completely filled with cooked food, disposable gloves that appeared to have been washed for reuse, and a porous wooden chopping block.
The caterer’s four food workers reported no recent illness. Stool specimens from the food workers and from four ill attendees all tested negative for norovirus, Campylobacter, Escherichia coli O157, Salmonella, and Shigella at the Connecticut State Public Health Laboratory. All eight specimens were sent to the Minnesota Department of Health Public Health Laboratory, where additional testing was available. Two specimens from food workers were positive for enterotoxigenic Escherichia coli by polymerase chain reaction, but no enterotoxigenic E. coli colonies were isolated. Seven specimens (four from food workers and three from attendees) were culture-positive for Clostridium perfringens, and specimens from all attendees contained C. perfringens enterotoxin. Pulsed-field gel electrophoresis of 29 C. perfringens isolates from the culture-positive specimens found no matches among attendee isolates, but demonstrated a single matching pattern between two food worker specimens. No leftover food items were available for testing.
C. perfringens, a gram-positive, rod-shaped bacterium, forms spores allowing survival at normal cooking temperatures and germination during slow cooling or storage at ambient temperature (1). Diarrhea and other gastrointestinal symptoms are caused by C. perfringens enterotoxin production in the intestines. Vomiting is rare and illness is usually self-limited, although type C strains can cause necrotizing enteritis (1).
Symptoms reported were consistent with C. perfringens infection, with a predominance of diarrhea, and median diarrhea onset time was at the lower end of the typical C. perfringens incubation period (6–24 hours) (1). C. perfringens enterotoxin detection in the stool of two or more ill persons confirms C. perfringens as the outbreak etiology (2). Both C. perfringens and enterotoxigenic E. coli can colonize asymptomatic persons (3,4), which might explain the presence of these pathogens in the stools of asymptomatic food workers. Pulsed-field gel electrophoresis did not identify the C. perfringens strain responsible for the outbreak, but findings add to the evidence for a wide variety of C. perfringens strains, not all producing C. perfringens enterotoxin (5).
C. perfringens outbreaks are typically associated with improper cooling or inadequate reheating of contaminated meats (1), which might have occurred with the beef dish. The restaurant was advised about the need for adequate refrigeration and best practices for cooling foods, including using stainless steel rather than plastic containers, avoiding filling containers to depths exceeding two inches, avoiding stacking containers, and ventilating hot food. Upon follow-up inspection, staff members discarded disposable gloves after one use, used only food-grade cutting boards, and maintained proper food temperatures for hot holding, cold holding, cooling, and reheating, as outlined in the Food and Drug Administration Food Code.
An estimated 1 million illnesses in the United States each year are attributable to C. perfringens, but fewer than 1,200 illnesses are reported annually with C. perfringens outbreaks (6). C. perfringens testing is not routine for foodborne outbreaks; even if testing is unavailable, C. perfringens should be considered when improper cooling, inadequate reheating, and improper temperature maintenance of meat are identified.
That’s how much of a food safety nerd I am, and why I don’t get invited to dinner parties (and, I can be an asshole).
King County Public Health investigated an outbreak of Campylobacter associated with a single meal party at Café Juanita in Kirkland on June 24, 2017.
On July 24th, Public Health learned about two ill persons from a single meal party during an interview with an ill person diagnosed with Campylobacter. We were not able to confirm illness information about the second ill person until August 16th. No other ill persons have been identified.
The ill persons shared multiple food items, including foie gras. Foie gras has been linked to other Campylobacter outbreaks in the past, particularly when eaten raw or undercooked.
Public Health’s Environmental Health inspectors visited the restaurant on August 17th. During the field inspection, inspectors observed the cooking process and checked the final cooking temperature of the foie gras. Although it reached a safe temperature during the inspection, workers had not been using a thermometer. They were instructed to use a food thermometer to ensure that all foods are reaching the correct temperatures to kill harmful bacteria that may be present. The restaurant worked cooperatively with Public Health.
Inspectors made a return visit on August 22nd and reviewed sources and preparation steps of the other foods that the two cases may have also consumed.
Stephanie Strom of the NY Times writes that one of the chief selling points of the Impossible Burger, a much ballyhooed plant-based burger patty, is its resemblance to meat, right down to the taste and beeflike “blood.”
Those qualities, from an ingredient produced by a genetically engineered yeast, have made the burger a darling among high-end restaurants like Momofuku Nishi in New York and Jardinière in San Francisco, and have attracted more than $250 million in investment for the company behind it, Impossible Foods.
Bill Gates is an investor.
That makes me want to run to my Mac.
The genetically engineered yeast thingy is just thrown in there to raise alarm.
My 1985 daily squash partner, Andy, was working on genetically engineered yeast for wine back in the day. Our bottling parties were legend.
Now, its secret sauce — soy leghemoglobin, a substance found in nature in the roots of soybean plants that the company makes in its laboratory — has raised regulatory questions.
Impossible Foods wants the Food and Drug Administration to confirm that the ingredient is safe to eat. But the agency has expressed concern that it has never been consumed by humans and may be an allergen, according to documents obtained under a Freedom of Information request by the ETC Group as well as other environmental and consumer organizations and shared with The New York Times.
“F.D.A. believes the arguments presented, individually and collectively, do not establish the safety of soy leghemoglobin for consumption,” agency officials wrote in a memo they prepared for a phone conversation with the company on Aug. 3, 2015, “nor do they point to a general recognition of safety.”
Impossible Foods can still sell its burger despite the F.D.A. findings, which did not conclude soy leghemoglobin was unsafe. The company plans to resubmit its petition to the agency.
Impossible Foods is finding out what happens when a fast-moving venture capital business runs headlong into the staid world of government regulation.
In the case of Impossible Foods, the debate centers on its use of soy leghemoglobin, which the company’s engineered yeast produces and forms an important ingredient behind the business.
The company was started in 2011 by Pat Brown, a chemist at Stanford University. His approach, involving genetics, microbiology and cutting-edge chemistry attracted venture capitalists also eager to find plant-and lab-based replacements for hamburgers and chicken wings.
Impossible Foods sought to woo top chefs with a splashy sales pitch about how the burger mimicked the aroma, attributes and taste of real beef. When soy leghemoglobin breaks down, it releases a protein known as heme, giving it that meatlike texture.
Within three years of its founding, Impossible Foods landed big-name investors like Khosla, Mr. Gates and the Hong Kong billionaire Li Ka-Shing. This month, Temasek Holdings, Singapore’s sovereign wealth fund, joined an investment round that added $75 million to the company’s coffers.
“I love V.C.s and particularly the ones that invested in us,” Mr. Brown said at a TechCrunch conference in May, referring to venture capital firms. “But it’s truly astonishing how little diligence they do in terms of the actual science that underlies some tech companies.”
The F.D.A.’s approval is not required for new ingredients. Companies can hire consultants to run tests, and they have no obligation to inform the agency of their findings, a process known as self-affirmation.
Impossible Foods adhered to that procedure, concluding in 2014 that soy leghemoglobin was safe. But it went further, seeking the regulator’s imprimatur.
“We respect the role the F.D.A. plays in ensuring the safety of our food supply, and we believe the public wants and deserves transparency and access to any information they need to decide for themselves whether any food they might eat is safe and wholesome,” Rachel Konrad, a spokeswoman for Impossible Foods, wrote in an email.
The F.D.A., however, wanted the company to show the ingredient was safe specifically for humans. It told Impossible Foods to establish the safety of the more than 40 other proteins that make up part of its soy leghemoglobin. F.D.A. officials said the company’s assessment of the potential for the ingredient to be an allergen was deficient.
“This product has been touted as the ‘secret sauce’ in the Impossible Burger,” said Jim Thomas, program director at the ETC Group, the Canadian environmental organization that started the Freedom of Information request. “Now we know that the F.D.A. had questions about it, but it was put on the market anyway.”
Ms. Konrad defended the burger, writing it “is entirely safe to eat” and “fully compliant with all F.D.A. regulations.” She said the company was “taking extra steps to provide additional data to the F.D.A. beyond what’s required.”
Impossible Foods, she said, has tested its ingredient on rats fed “well above” the amount of soy leghemoglobin in its burger. Ms. Konrad said the company’s expert panel had determined those tests also demonstrated the ingredient was safe, and that the company would thus resubmit its petition for F.D.A. confirmation this month.
This is a novel food, and makes Canada’s approach to regulation of food safety sane, for a while.
