Education

  • Posted: January 4th, 2012 - 6:04am by Doug Powell

    People from well-educated families are almost twice as likely to suffer from some dangerous food allergies as others — possibly because their bodies’ natural defences have been lowered by rigorous hygiene and infection control, suggests a new Canadian study.

    The research from McGill University also found that immigrants were about half as likely to be afflicted by the allergies, perhaps reflecting differences in diet and environment between their countries of origin and Canada.

    The study, just published in the Journal of Allergy, was meant to address an enduring medical mystery: Why have so many people in certain industrialized countries developed violent reactions to peanuts, shellfish and other foods in recent decades?

    The link to higher education may be explained by what is called the hygiene hypothesis, the unproven idea that smaller families, cleaner homes, more use of antibiotics to treat infections and vaccines to prevent them have curbed development of the immune system, said Dr. Moshe Ben-Shoshan, who led the research. That in turn could make some people more susceptible to allergy.

    If the hypothesis does actually explain some food reactions, though, parents may not be able to do much about it, admitted the allergist at Montreal Children’s Hospital. The benefits of such health products as antibiotics and vaccines easily outweigh the risk of children developing serious allergies, said Dr. Ben-Shoshan.
    “We can’t suggest we become dirtier and expose our children to more bacteria,” he said. “If the price of having fewer allergies is more infection, I don’t know any parent who would expose their child to more infection.”

    The study’s findings are far from conclusive but they, and the hygiene hypothesis as an explanation, seem plausible, said Dr. Stuart Carr, president of the Canadian Society of Allergy and Clinical Immunology. He also cautioned, however, that translating the knowledge into preventive action would be complicated.

    I cringe when someone says, ‘food safety is simple.’

    A review of existing studies by the U.K. Food Standards Agency found that, although people “are often aware of good food hygiene practices, many people are failing to chill foods properly, aren’t following advice on food labels and aren’t sticking to simple hygiene practices that would help them avoid spreading harmful bacteria around their kitchens.”

    Yes, individuals are impervious to risk; been known for decades.

    And there’s that word, ‘simple’ again.

    I especially cringe when someone says, ‘cooking a hamburger is easy with these simple food safety steps.’

    Ho Phang and Christine Bruhn report in the current Journal of Food Protection that in video observation of 199 California consumers making hamburgers and salad in their own kitchens, handwashing was poor, only 4% used a thermometer to check if the burger was safely cooked, and there were an average of 43 cross-contamination events per household.

    There’s some good data in the paper about what consumers do in their own kitchens, and the results are an additional nail in the self-reported-food-safety-survey coffin: people know what they are supposed to do but don’t do it.

    But what the paper doesn’t address is how to influence food safety behaviors. Instead, the University of California at Davis authors fall back on the people-need-to-be-educated model, without out providing data on how that education – I prefer compelling information – should be provided.

    The authors state:

    • educational materials need to emphasize the important role of the consumer in
    preventing foodborne illness and that foodborne illnesses can result from foods prepared in the home.;

    • the gap between the awareness of the importance of hand washing and the actual practice of adequate hand washing should be addressed by food safety educators.

    • food safety educators should address the lack of reliability of visual cues during cooking (stick it in -- dp);

    • food safety educators should emphasize faucet cleaning with soap and water as a way of preventing cross-contamination; and,

    • ignorance about food irradiation point to a further need for education.

    The authors do correctly note that program to promote the use of thermometers when cooking burgers, initiated by the introduction of Thermy in 2000, has not been successful. So why do more education?

    And the E. coli O157:H7 outbreak in Jack-in-the-Box hamburgers happened in Jan. 1993, not 1994 as stated in the paper; someone should have caught that.

    Abstract:
    Ground beef has been linked to outbreaks of pathogenic bacteria like Escherichia coli O157:H7 and Salmonella. Consumers may be exposed to foodborne illness through unsafe preparation of ground beef. Video footage of 199 volunteers in Northern California preparing hamburgers and salad was analyzed for compliance with U.S. Department of Agriculture recommendations and for violations of the U.S. Food and Drug Administration's Food Code 2009. A questionnaire about consumer attitudes and knowledge about food safety was administered after each filming session. The majority of volunteers, 78%, cooked their ground beef patties to the Food Code 2009 recommended internal temperature of 155°F (ca. 68°C) or above, and 70% cooked to the U.S. Department of Agriculture consumer end-point guideline of 160°F (ca. 71°C), with 22% declaring the burger done when the temperature was below 155°F. Volunteers checked burger doneness with a meat thermometer in 4% of households. Only 13% knew the recommended internal temperature for ground beef. The average hand washing time observed was 8 s; only 7% of the hand washing events met the recommended guideline of 20 s. Potential cross-contamination was common, with an average of 43 events noted per household. Hands were the most commonly observed vehicle of potential cross-contamination. Analysis of food handling behaviors indicates that consumers with and without food safety training exposed themselves to potential foodborne illness even while under video observation. Behaviors that should be targeted by food safety educators are identified.

    It’s the first day of spring in Australia, which means daughter Courtlynn is heading back to the Northern Hemisphere to start school, the temperature is soaring, and an entire month awaits of unverified, repetitious and banal food safety messages aimed at consumers.

    The Brits got an early start about a week ago.

    The Food Standards Agency published a review of existing studies that explore how people manage food safety in their homes.

    The report found that, although they are often aware of good food hygiene practices, many people are failing to chill foods properly, aren’t following advice on food labels and aren’t sticking to simple hygiene practices that would help them avoid spreading harmful bacteria around their kitchens. People often know what they should be doing, but they don’t put this knowledge into practice, believing they are not vulnerable to food poisoning.

    Yes, individuals are impervious to risk; been known for decades.

    There’s oodles of material to pick through in the full report, but my favorite is this: people have a low level of awareness of recommended good practice with respect to cooking (correct final cooked temperature).

    Maybe FSA should stop telling people to cook things until they are ‘piping hot.’

    Food safety isn’t just a consumer thing – it’s an everybody thing. Forget the farm groups and industries that fund the blame-consumers approach. What did consumers have to do with outbreaks involving peanut butter, pizza, pot pies, pet food, pepper and produce (washing don’t do much). That’s just the Ps.

    Reciting prescriptive instructions – cook, clean, chill, separate – like some fascist country line dancing instructor benefits no one. Food safety is complex, and it takes effort.

    Maybe I’m losing something in translation, but Xinhua reports that experts in China have called for strengthening moral education to ensure food safety following a string of scandals in recent months.

    Zhao Chenggen, an expert at the School of Government at Peking University, said on Wednesday that to promote moral education is conducive to urging food producers to place a higher value on public health.

    Under the influence of moral cultivation, food producers could enhance their subjective consciousness to resist ill-gotten gains through adding toxic materials into food, he said.

    "Moral decline in the food industry is more terrible than that in social communications," said another expert, Xu Yaotong, a professor of political science at the National School of Administration.

    Premier Wen Jiabao said, "A country without the improved quality of its people and the power of morality will never grow into a mighty and respected power.”

    Wen said that advancing the moral and cultural construction would help safeguard normal production, life and social order, as well as to eradicate the stain of swindling, corruption and other illegal conduct.

    There are some recurring myths in the public discussion of foodborne illness and the reasons 76 million Americans barf every year from the food and water they consume, and the New York Times is recycling them all.

    Author Eric Schlosser (“Unsafe at Any Meal,” New York Times, Op-Ed, July 25) overstates the protective role of government while casting aspersions against what he calls industrial agricultural and unchecked corporate power. His rant on the Colbert Report last year was legendary.

    Henry Miller who used to do biotechnology work at the U.S. Food and Drug Administration writes in the Times this morning, “The vast majority of food poisoning is caused by individuals’ mishandling of food; common lapses include the mishandling or undercooking of poultry and the inadequate refrigeration of food. More expansive, expensive, onerous regulation is not the answer; better education of consumers is.”

    Our review of the data found a complete mish-mash about where “the vast majority of food poisoning illness is caused” and that no conclusions could be drawn. Produce, pot pies, pet food and pizzas don’t have much to do with consumers. And how would this better education be conducted?

    If someone wrote in and said Americans have the safest food supply in the world, all the big three mythologies would be represented.

    Food safety is not simple and the public discussion – which affects individual behaviors from farm-to-fork – is a mess.

    Toronto-based Blue Rodeo’s Five Days in July was my favorite album of 1993 (at least the first 6 tunes). The song, Hasn’t Hit Me Yet, remains evocative. I got to meet-and-greet the band at one of those corporate concert thingies when they performed for the Canadian Council of Grocery Distributers in 2003.

    Chapman got to see them last night somewhere in North Carolina (right, exactly as shown). About 100 people showed up.

    I talk about good music because it makes me smile. When I hear about how people want to educate consumers, it makes me frown.

    Some people write in peer-reviewed journals, some people pontificate. Me and Chapman and some Blue Rodeo groupies have written several papers about how to get the attention of food handlers, at home, in food service or on the farm, in the same way a catchy tune gets peoples’ attention.

    Others say, educate consumers.

    Kansas State University meat scientist James Marsden says he hears it over and over again – that there’s a need to better educate consumers about proper food handling and cooking. Such an effort could go a long way in minimizing the risk of foodborne illness.

    Maybe Marsden should listen to other folks. Marsden did acknowledge, that food safety is everyone’s responsibility – from the producer to the processor to the consumer.

    I’m all for providing food safety information in a compelling, creative and critically-sound manner. However education is something people do themselves.

    Lewis Lapham wrote in Harper’s magazine in the mid-1980s about how individuals can choose to educate themselves about all sorts of interesting things, but the idea of educating someone is doomed to failure. Oh, and it’s sorta arrogant to state that others need to be educated; to imply that if only you understood the world as I understand the world, we would agree and dissent would be minimized.

    These may be subtle semantics – to communicate with rather than to; to inform rather than educate – but they set an important tone.

    I know this is repetitive. Guess it hasn’t hit me yet.

    I started picking people up about 7 p.m. Amanda, Sarah, Janis, Lynn and Marty.

    Marty was last and not ready, as usual.

    Marty had no reason going to the first food safety educators conference in Washington, D.C. in 1997. He was working as a student life advisor or something but, I had gotten in the habit of taking Marty along on the 12-hour D.C. road trip from Guelph –got lost once in some New York mountains in the middle of the night and thought we were going to die – for fun and driving chores.

    The 1996 Nissan Quest minivan still had the new car smell, and as a new prof with a carload of students, I decided driving all night was better than dishing out non-existent cash for an extra night of hotel rooms.

    We arrived in Georgetown about 7:30 a.m., ate at a dive, and found the on-campus conference room. People looked at us like we had just rolled out of a vehicle and been driving all night.

    We had.

    Most of us went and changed into fresh clothes, while Marty crashed somewhere until the room was available.

    The conference started and we were pumped.

    I may have fallen asleep.

    I remember that Peter Sandman gave a keynote and was treated like a rock star – I thought he was ineffectual, especially when it came to the hazard and outrage around foodborne illness.

    There were descriptions of many food safety education programs but the evaluation components were either non-existent or sucked.

    There was a big deal about social marketing, presented to the attendees like we had all arrived on the short bus.

    I remember going out to a Georgetown bar later that night, watching The Truth About Cats and Dogs in the hotel room while Marty farted, and commenting that Janis looked like Janeane Garofalo. I remember the drive home.

    I don’t remember much about the conference.

    Which is why I haven’t gone back.

    Tomorrow, the International 2010 Food Safety Education Conference kicks off in Atlanta and its focus is to identify “communication and education strategies to increase the public’s knowledge of the causes of foodborne illnesses and improve food safety practices.”

    Admirable goals. But what has happened since 1997?

    I’m all for providing food safety information in a compelling, creative and critically-sound manner. However education is something people do themselves. Lewis Lapham wrote in Harper’s magazine in the mid-1980s about how individuals can choose to educate themselves about all sorts of interesting things, but the idea of educating someone is doomed to failure. Oh, and it’s sorta arrogant to state that others need to be educated; to imply that if only you understood the world as I understand the world, we would agree and dissent would be minimized.

    These may be subtle semantics – to communicate with rather than to; to inform rather than educate – but they set an important tone.

    At least it’s not a consumer food safety education conference. With outbreaks in pizza, pot pies, pet food, peanut butter, bagged spinach, carrot juice, lettuce, tomatoes, canned chili sauce, hot peppers, cookie dough, and white pepper, I’m not sure what consumers have to do with it.

    Chapman is going, apparently as part of a southeast IKEA tour for his wife, and also to present a paper we wrote entitled, I updated my Facebook status to ‘I just got food poisoning:’ using social networking services (SNS) to communicate food safety risks. The abstract is below.

    Bill Marler says he’s gong to educate consumers by handing out refrigerator magnets at the conference.

    Me, I’ll be hanging out somewhat east of the 100th meridian, wondering why Americans don’t understand The Tragically Hip (especially the early stuff). 

    Chapman, B. and Powell, D. 2010. I updated my Facebook status to “I just got food poisoning”: using social networking services (SNS) to communicate food safety risks. FSIS/NSF Food Safety Education Conference. March 24, 2010. Atlanta Georgia.

    Up to 30 per cent of individuals in developed countries become ill from the food and water they consume each year. Recent outbreaks of foodborne illness involving produce, peanut butter and potpies have further elevated the public discussion of microbial food safety risks. With the expansion and ease-of-use of non-traditional, Internet-based communication tools such as Facebook, Twitter, Wikipedia, YouTube and blogs, individuals are discussing high-profile food crises online. As an estimated 60 per cent of online American adults use SNS, an opportunity exists to utilize these communities to engage individuals around foodborne risks by providing information and establishing relationships, to prepare for or mitigate potential catastrophic incidents. The rapid dialogue between individuals with common food safety interests can impact belief formation and affect food decisions. Using case study methodology and media analysis of the coverage of recent outbreaks of E. coli O157 linked to spinach and Salmonella linked to fresh tomatoes and peppers, a catalogue of mediums and will be presented. Through examples gleaned from barfblog.com and bites.ksu.edu an online food safety communication template and strategies for food safety communicators will also be presented. Understanding target audiences, using communication technology while providing rapid messages can enhance both risk management awareness and trust with stakeholders.  Communicators developing food risk behavior change programs can be more effective by monitoring and utilizing diverse media to adjust strategies and maintain message relevance.

    Allen Mozek, M.P.H., Supervising Food Inspector, New York State Department of Agriculture & Markets, writes in this contribution to barfblog.com that,

    I find that food inspectors in all regulatory agencies have a tendency to confuse their inspection techniques with their investigative techniques. This results in lost evidence (primarily food samples) to prove the cause of a foodborne illness.

    A little background...

    The spirit of public health and food inspection is education and prevention. Food inspectors are allowed access without a warrant because they are looking for compliance, whereas police officers are denied access without a warrant because they are looking for evidence. This difference in emphasis on compliance versus evidence gathering reflects a difference in approaches. Evidence is gathered during routine inspection, but a food inspector's initial expectations are compliance (or so says public health law).

    Unfortunately, the daily emphasis on education and prevention creeps into investigations of foodborne disease. I say "creep" because I suggest that the habit of educating prevents inspectors from finding the evidence necessary to solve cases.

    Once a case is reported, an inspector should be gathering evidence and
    no longer educating at the expense of "showing your hand" or otherwise
    reveal too much information. I think it's about changing gears from an
    inspection mentality to an investigation mentality -- the two are very
    different.

    Chapman asks me the other day, “How do we fight the dogma?”

    Is that like fight the power? Fight the man? Fight for your right to party?

    What he was talking about was food safety dogma, the kind where seemingly good people give bad food safety advice. Like the Brits and their piping hot turkey.

    But this was directed at home. Why do good people reference bad advice, such as the cumbersomely named U.S. Partnership for Consumer Food Safety Education, and their Holiday food safety success kit, which says people should always wash their hands for 20 seconds with warm water and never defrost turkey on the counter (with exclamation marks, so readers know they are seriously serious).

    When washing hands, water temperature doesn’t matter, 10 seconds is sufficient
    . Turkey can be thawed on the counter, don’t leave it there forever and don’t let the cat nibble on it.

    The dogma part is, where are the references? How do groups like the horribly named Partnership come up with food safety advice? Is it some magical mystery tour or is there some reference to something credible? Who knows. It’s not publicly available.

    So why anyone would reference the awkward Partnership as a credible source is bizarrely baffling.

    There’s no shortage of food safety news; there is a shortage of evidence-based, incisive approaches that challenge food safety norms and may eventually lead to fewer sick people.

    The International Food Safety Network evolved into bites.ksu.edu over the past year as a way of consolidating and making food safety news delivery more efficient. In addition to the web repository, the bites-l electronic newsletter is distributed 2-3 times a day to a dedicated subscriber base of some 10,000 in 60 countries; a list that has been focused and refined by offering continuous, daily food safety news since 1994. barfblog.com – averaging well over 10,000 unique hits a day -- along with weekly food safety infosheets (available in multiple languages), and videos, are now prominent food safety resources.

    Sponsorship opportunities are now available for bites.ksu.edu, barfblog.com, and the bites-l listserv (as well as the infosheets and videos; how about a movie?).

    In addition to the public exposure – why not stick your company logo on the bites-l newsletter that directs electronic readers to your home site or whatever you’re flogging that week -- and reaching a desired audience, you can receive custom food safety news and analysis. We’ve also resurrected the food safety risk analysis team – assessment, management and communication – and offer 24/7 availability and insanely rapid turnaround times. If your group has a food safety issue -- short-term or long-term -- work with us, rather than having us write it up in barfblog.com, book chapters and scholarly papers as another case study of what not to do.

    The money is used to support the on-going expenses of the news-gathering and distribution activities, and to develop the next generation of high school, undergraduate and graduate students who will integrate science and communication skills to deliver compelling food safety messages using a variety of media. Research, training and outreach are all connected in our food safety world.

    Here’s some additional information.

    bites.ksu.edu is a unique comprehensive resource hosted at Kansas State University for all those with a personal or professional interest in food safety. We find credible, current, evidence-based information on food safety and make it accessible to domestic and international audiences through multiple media. Sources of food safety information include government regulatory agencies, international organizations such as the World Health Organization (WHO) and the Food and Agriculture Organization of the United Nations (FAO), peer-reviewed scientific publications, academia, recognized experts in the field and other sources as appropriate.

    All bites activities emphasize engaging people in dialogue about food-related risks, controls and benefits, from farm-to-fork. bites strives to provide reliable, relevant information in culturally and linguistically appropriate formats to assist people in identifying, understanding and mitigating the causes of foodborne illness.

    bites LISTSERV
    The bites.ksu.edu listserv is a free web-based mailing list where information about current and emerging food safety issues is provided, gathered from journalistic and scientific sources around the world and condensed into short items or stories that make up the daily postings. The listserv has been issued continuously since 1995 and is distributed daily via e-mail to thousands of individuals worldwide from academia, industry, government, the farm community, journalists and the public at large.
    The listserv is designed to:
    •    convey timely and current information for direction of research, diagnostic or investigative activities;
    •    identify food risk trends and issues for risk management and communication activities; and
    •    promote awareness of public concerns in scientific and regulatory circles.
    The bites listserv functions as a food safety news aggregator, summarizing available information that can be can be useful for risk managers in proactively anticipating trends and reactively address issues. The bites editor (me – dp) does not say whether a story is right or wrong or somewhere in between, but rather that a specific story is available today for public discussion.

    barblog.com
    barfblog.com is where Drs. Powell, Chapman, Hubbell and assorted food safety friends offer evidence-based opinions on current food safety issues. Opinions must be evidence-based – with references – reliable, rapid and relevant. The barfblog authors edit each other – viciously.
     

    TWITTER
    Breaking food safety news items that eventually appear in bites or barfblog are often posted on Twitter (under barfblog or benjaminchapman) for faster public notification.

    INFOSHEETS
    Food safety infosheets
    are designed to influence food handler practices by utilizing four attributes culled from education, behavioral science and communication literature:
    •    surprising and compelling messages;
    •    putting actions and their consequence in context;
    •    generating discussion within the target audiences’ environments; and
    •    using verbal narrative, or storytelling, as a message delivery device.
    Food safety infosheets are based on stories about outbreaks of foodborne illness sourced from the bites listserv. Four criteria are used to select the story: discussion of a foodborne illness outbreak; discussion of background knowledge of a pathogen (including symptoms, etiology and transmission); food handler control practices; and emerging food safety issues. Food safety infosheets also contain evidence-based prescriptive information to prevent or mitigate foodborne illness related to food handling. They are now available in French, Spanish and Portugese.

    bites bistro videos
    A nod to the youtube generation, but we don’t really know what we’re doing.

    These are the various information products we deliver daily, in addition to research, training and outreach. If you or your group is interested in sponsoring any or all of these food safety activities, please contact me directly.
