    Kansas State University came out with their version of the Chapman and me and other Blue Rodeo groupies study this morning.

    Posting graphical, concise food safety information sheets in the kitchens of restaurants can help reduce dangerous food safety practices and create a workplace culture that values safe food, according to a new paper co-authored by Kansas State University's Doug Powell.

    The study, "Assessment of food safety practices of food service food handlers: testing a communication intervention," was published in the June issue of the Journal of Food Protection. It was authored by Ben Chapman, assistant professor of food safety at the North Carolina State University; Powell, associate professor of food safety at K-State; Katie Filion, master's student in biomedical science at K-State; and Tiffany Eversley and Tanya MacLaurin of the University of Guelph in Canada.

    It's the first time that a communication intervention using food safety info sheets has been validated to work, Powell said.

    Powell and Chapman came up with the idea for food safety info sheets to promote discussion and improve food safety behaviors while playing hockey at the University of Guelph in 2003. Chapman was a graduate student at the time.

    "Chapman and I played hockey a lot, and there was a bar and restaurant that overlooked the one ice surface where we often had after-hockey food safety meetings with our industry, provincial and federal government colleagues," Powell said. "We had all this food safety information, and the manager of the restaurant was into food safety, so we thought that if daily sports pages are posted on the walls and doors of washroom stalls, why not post engaging food safety information in kitchens for restaurant employees to read."

    As part of his doctoral research, Chapman partnered with a food service company in Canada and placed small video cameras in unobtrusive spots around eight food-service kitchens that volunteered to participate in the study. There were as many as eight cameras in each kitchen, which recorded directly to computer files that were reviewed by Chapman and others.

    The work built on other direct food safety observational studies conducted at K-State and published in the British Food Journal in 2009.

    Food safety info sheets, highlighting the importance of hand washing or preventing cross-contamination, for example, were then introduced into the kitchens, and video was again collected. The researchers found that cross-contamination events decreased by 20 percent, and hand-washing attempts increased by 7 percent.

    The increases show the information sheets work, Powell said. "Food safety messages like 'Employees must wash hands' signs in bathrooms just don't work," he said.

    Since September 2006 more than 150 food safety info sheets have been produced and are available for anyone to use, http://www.foodsafetyinfosheets.com. The website has a search function and offers automatic email alerts and RSS feeds.

    K-State's Filion coded much of the video as an undergraduate student researcher in Canada. MacLaurin, who collaborated on the research, was born on a farm/ranch in Kansas and received all her degrees from K-State before joining the School of Hospitality and Tourism Management at the University of Guelph in 1991, where she subsequently collaborated with Powell.

    The paper and study abstract are available at:

    Posting graphical, concise food safety stories in the back kitchens of restaurants can help reduce dangerous food safety practices and create a workplace culture that values safe food.

    It’s the first time that a communication intervention such as food safety information sheets have been validated to work using direct video observation in eight commercial restaurant kitchens.

    “The food safety messages we’ve looked at are as effective as those ‘Employees must wash hands’ signs in bathrooms.,” said Dr. Douglas Powell, an associate professor of food safety at Kansas State University and one of the co-authors on a new paper in the Journal of Food Protection. “They just don’t work.”

    Powell and then graduate student, Ben Chapman, now an assistant professor of food safety at North Carolina State University, came up with the idea for food safety infosheets to promote discussion and improve food safety behaviors while playing hockey at the University of Guelph in 2003.

    “Chapman and I were playing hockey a lot,” says Powell, “and there was a bar and restaurant that overlooked the one ice surface where we often engaged in after-hockey food safety meetings with our industry, provincial and federal government colleagues. We had all this food safety information, and the manager of the bar around 2003 was into food safety, so we thought, if daily sports pages are posted above urinals and on the doors of washroom stalls, why not engaging food safety information?”

    As part of his PhD research, Chapman partnered with a food service company in Canada and placed small video cameras in unobtrusive spots around eight food-service kitchens that volunteered to participate in the study. There were as many as eight cameras in each kitchen, which recorded directly to computer files and later reviewed by Chapman and others.

    The work built on other direct food safety observational studies conducted at Kansas State University and published in the British Food Journal in 2009.

    Food safety inforsheets, highlighting the importance of handwashing or preventing cross-contamination, for example, were then introduced into the kitchens, and video was again collected. The researchers found that cross-contamination events decreased by 20 per cent, and handwashing attempts increased by 7 per cent.

    Since September 2006 over 150 food safety infosheets have been produced and are available to anyone at www.foodsafetyinfosheets.com. The website has had a recent redesign, adding a search function, automatic email alerts and RSS feeds.

    Katie Filion, who coded much of the video as an undergraduate student researcher, has moved from Canada and is now completing a Master’s degree with Powell at Kansas State University. She has just returned from a year of research with the New Zealand Food Safety Authority helping to design a national restaurant inspection disclosure system.

    Dr. Tanya MacLurin, who collaborated on the research, was born on a farm/ranch in Kansas and received all her degrees from Kansas State University before joining the School of Hospitality and Tourism Management at the University of Guelph in 1991, where she subsequently collaborated with Powell.

    “Assessment of Food Safety Practices of Food Service Food Handlers: Testing a Communication Intervention”
    Authors: Benjamin J. Chapman, North Carolina State University; Douglas A. Powell, Katie Fillion, Kansas State University; Tiffany Eversley, Tanya MacLaurin, University of Guelph
    Published: June 2010, Journal of Food Protection

    Abstract: Globally, foodborne illness affects an estimated 30% of individuals annually. Meals prepared outside of the home are a risk factor for acquiring foodborne illness and have been implicated in up to 70% of traced outbreaks. The Centers for Disease Control and Prevention has called on food safety communicators to design new methods and messages aimed at increasing food safety risk-reduction practices from farm to fork. Food safety infosheets, a novel communication tool designed to appeal to food handlers and compel behavior change, were evaluated. Food safety infosheets were provided weekly to food handlers in working foodservice operations for 7 weeks. It was hypothesized that through the posting of food safety infosheets in highly visible locations, such as kitchen work areas and hand washing stations, that safe food handling behaviors of foodservice staff could be positively influenced. Using video observation, food handlers (n ~ 47) in eight foodservice operations were observed for a total of 348 h (pre- and postintervention combined). After the food safety infosheets were introduced, food handlers demonstrated a significant increase (6.7%, P , 0.05, 95% confidence interval) in mean hand washing attempts, and a significant reduction in indirect cross-contamination events (19.6%, P , 0.05, 95% confidence interval). Results of the research demonstrate that posting food safety infosheets is an effective intervention tool that positively influences the food safety behaviors of food handlers.

    A blogger named Jenny called me last week and asked me how I buy meat.

    So this is what I told her as documented in her blog, Dinner A Love Story.

    My first guest is Doug Powell, associate professor, food safety, Dept. Diagnostic Medicine/Pathobiology, Kansas State University and the father of five girls. His entertainingly combative barfblog.com regularly takes Whole Foods and (no!!!) Michael Pollan to task.

    So Doug Powell, how do you buy meat?

    “I go to the biggest supermarket I can find — Dillons, Walmart, Krogers. I’ll buy a whole chicken at Dillons for some ridiculously low price, like 99 cents a pound. Because I know they have quality control measures in place to reduce microbial loads before they get in the store. I would never shop at any of those places like Whole Foods. What they are peddling is complete nonsense from a safety point a view. Whole Foods is so concerned about being natural and whatever else that they don’t pay attention to the basics like cross-contamination. They’re sloppy about that.

    “It’s not about lovingly raising an animal which I’m sure lots of farmers do. It’s about testing. In separate USA Today stories last year, both Costco and McDonalds were highlighted for their rigorous safety standards. I’m not talking quality here, I’m talking safety. Given the number of things they serve, those places can’t afford to screw up.

    “When I buy ground beef, I treat it like hazardous waste, and make burgers mixed with about 20 per cent ground turkey. A butcher grinding meat in front of me means nothing from a safety perspective. If there’s poop on the outside, it’s now on the inside, which is why I always — always — use a tip-sensitive digital thermometer to make sure any food is properly cooked. There’s just too many people out there getting sick.”

    Maybe it’s time to get back to the family compound in Newport, Wales.

    Health officials in Newport are investigating eight cases of salmonella at the city's Royal Gwent Hospital.

    A hospital spokesman said it was not yet clear whether those suffering from the bacterial infection had caught it in the community or in hospital.

    GPs in the area have been contacted to alert them to the possibility the bug may be present in the community.

    Salmonella is usually associated with eating contaminated foods. The eight people are said to be recovering well.

    Some showed symptoms of the illness when they came into hospital but others did not, the spokesman said.

    I did not get lost in Las Vegas, Hangover-style, and couldn’t remember where I was for the past few days. Chapman didn’t go on an oyster-eating binge. Katie didn’t get lost on the beach in NZ.

    Whenever someone talks about computers and says, “Oh, that’s easy, we’ll just change it over,” whether it’s a home printer or a blog that people expect to work, there will be issues.

    barfblog.com has had a lot of issues.

    There were lots of posts over the weekend that you probably never heard about. They mainly just involved me barfing and taking pictures in bathrooms.

    We’re aware of the limitations and working our way through the issues. If you received this notification, then progress is being made.

    The Internet is useful for all sorts of things beyond food safety – it’s been a boon for genealogy research.

    Which is how we ended up meeting with Carl yesterday at The Fountain Inn in Tipton, U.K., not far from Birmingham.

    At one point Carl asked, “So what do you think of it over here?”

    “Oddly comfortable.”


    Carl got in touch with me electronically after I posted something about William Perry, aka The Tipton Slasher, who was the bare-knuckle heavyweight boxing champ of England from 1850-1857.

    Carl, who is descended from one of William Perry’s brothers, had detailed genealogies, constructed from birth and wedding certificates from the area. Tipton’s favorite son, the Slasher, had a son, William Perry II, who had a daughter, Sally or Sarah (she was called both), who married George Edward Powell I. They had a son, George Edward Powell II, who was my grandfather (and there’s nothing noble about the I and II; as cousin Keith said, they were grafters, which in Brit-speak means hard workers). So I got it wrong before, and the Slasher was my great-great-great grandfather.

    Sorenne and I posed in front of the statue of gramps in the park across from the Fountain Inn, which was the Slasher’s headquarters and training site before he became champ, and adjacent to one of the many canals constructed in the early 1800s to feed the industrial machine that was Birmingham. Perry started fighting fellow boatmen on the local canals to determine who would be first through the lockgates.

    And while we were too early for food, the Fountain Inn did proudly display its food license and level II catering certificate. The slideshow below has lots of cool pics.

    At the Dallas airport on Jan. 1, 2010, Amy ordered a hamburger while awaiting our flight to London’s Heathrow airport.

    “How would you like that done?”

    “160F please”

    “Does that mean medium-well?”

    Sigh.

    We booked an airport hotel for one night to recover from the trip – and to learn to drive on the wrong side of the road, with a stickshift on the wrong side of the steering wheel, and negotiate the many, many roundabouts.

    We ate dinner in the hotel bar where the only thing on the tele seemed to be … darts.

    Next it was off to Oxford where we spent a quite lovely day and night with a colleague of Amy’s and her husband (above, right). Dinner was baked wild haddock with parsnips, carrots and other roasted veggies.

    Today, we travelled to Newport, Wales, where many of the Powell’s hail from, including my father, grandfather, and others. We visited with a spry 80-year-old Keith Powell (below, left), a son of my grandfather’s brother, and dined at a carvery – a pub offering British fare of turkey, ham or beef carved from an intact bird or roast and served with unlimited roast veggies and other sides. While the food safety possibilities exist with carveries, this one was well-maintained and under the watchful eye of the carverer. Sorenne must have been starving as she gobbled up turkey, and when I refused a bowl for fear Sorenne would throw it at Keith or elsewhere, he asked as I put the meat directly on the high-chair table, “Are you sure that thing’s clean?”

    Must run in the family. When I returned the table-top, the first thing a server did was wipe it down with a cloth soaked in sanitary solution.

    Tomorrow, Cardiff.

    Today’s USA Today asked a bunch of food safety types what the government could do to improve the school lunch program.

    My full answer included,

    “Does it have to be government? They’re not very good at this stuff.”

     What got published this a.m., along with a photo by Dave Adams of Kansas State, was,

    "Government should set minimal standards and demand continuous improvement from all of its suppliers. More importantly, every cafeteria needs to make microbial food safety -- from hand washing to food handling -- part of the daily culture." 

    Douglas Powell, professor of food safety at Kansas State University and the publisher of barfblog.com.

    The story explains that in 1982, hamburgers from McDonald’s fast-food chain sickened at least 47 people in Oregon and Michigan. No one died, but the pathogen that caused the severe cramps, abdominal pain and bloody diarrhea turned out to be a little-known, especially dangerous form of the common stomach bacteria E. coli. The new subtype, E. coli O157:H7, produced a toxin that destroyed red blood cells and, in later cases elsewhere, caused kidney failure or death.

    Confounded by the discovery, McDonald's hired one of the nation's best-known food safety scientists, Michael Doyle, and told him, he recalls, "to bulletproof their system so E. coli never happened to them again."

    McDonald's reconsidered its old assumptions about food — from how often beef-processing plants should test ground beef to how well a hamburger must be cooked to kill off pathogens such as E. coli and salmonella.

    The results helped change the industry. For years, the federal food code said burgers had to be cooked only until their internal temperature reached 140 degrees; McDonald's tests showed the safe standard was 155 degrees and that the meat must register that temperature for at least 15 seconds.

    Microbial data also altered the demands McDonald's imposed on its suppliers.

    After a couple of years, the company saw that "about 5% of the suppliers could not get down to what we considered a reasonable level for salmonella and E. coli," says Doyle, now director of the University of Georgia's Center for Food Safety. "McDonald's worked hard with them, but they couldn't get there, so McDonald's let them go."

    The lesson, many analysts say, is that organizations with great buying power — such as fast-food chains or the school lunch program — can set higher standards, and industry ultimately will meet those standards because that's where the money is. The school lunch program purchases huge volumes of commodities such as beef, poultry and other staples –– $830 million worth in 2008.

    I like potlucks because of the social interaction and sampling different kinds of foods.

    I don’t like potlucks because who knows how various dishes are prepared, how they’ve been stored, and the dreaded double dipping.

    I told Erin Quinn of the Waco Tribune-Herald in Texas Monday that,

    Maybe you don’t want to eat the turkey noodle casserole made in the kitchen of the woman who you notice never washes her hands before leaving the bathroom.

    And maybe you should avoid the pumpkin cheesecake brought by the guy whose shirts are always covered with cat hair.

    “There is a lot of blind trust in it. Potlucks are really popular because they bring people together and do a lot of good things. But all of that fellowship can turn into a lot of sick people.”


    Powell recommends bringing a digital thermometer to potluck parties. He jokes that this is the reason he is hardly invited to potluck parties.

    Still, he said these parties are not inherently riskier than eating at restaurants. And most people, he said, wash their hands properly, have clean kitchens and cook food at the proper temperature.

    Allison Lowery, a spokeswoman for the Texas Department of State Health Services, said she, herself, eats at potlucks and is not too concerned about any risks.

    “You can’t go around being scared of everything. You’ve just got to have faith.”

    What we have discovered at bites.ksu.edu is that it’s best to be obvious and when possible, humorous. Food safety information can be boring, leading to complacency. We make important food safety information accessible and interesting to everyone, because everyone eats.

    bites.ksu.edu daily news e-mails are read by food safety professionals, journalists, students, chefs, regulators – really anyone -- around the world. barfblog has 10,000 unique visitors every day. Our downloadable infosheets are posted and read by food workers everywhere. We also do videos and crisis communication.

    From feedback and field studies, we know the bites-style works. (Here comes the NPR part of the letter.) While effective, it is also expensive. Stories have to be compiled, videos shot, infosheets designed, funny pictures found and coffee brewed. It takes time and it takes money.

    We need your help to not only continue what we are doing, but to expand the range of the people we help. We have found a formula that works.

    (Food Safety Info + A little commentary + A little Fun) x The Internet  = Safer Food.

    Whether you read barfblog, share the info from our e-mails with colleagues or post our infosheets in food prep areas, you have come to rely on bites, and that was our goal from the beginning.

    If you like what we are doing please take the time to make a tax-deductible contribution to bites or barfblog by clicking on the DONATE button at either bites.ksu.edu or barfblog.com.
