Food safety researcher and talk-show host Jon Stewart got it right back in 2002 when he said,

“If you think the 10 commandments being posted in a school is going to change behavior of children, then you think “Employees Must Wash Hands” is keeping the piss out of your happy meals. It's not.”

Instead, getting college students to wash hands, halt disease, requires giving them proper tools and spreading the word in ways that get attention: the path to poor hand sanitation is paved with good intentions, according to researchers from Kansas State and North Carolina State Universities.

As college campuses prepare for an expected increase in H1N1 flu this fall, the researchers said students' actions will speak louder than words.

"Many students say they routinely wash their hands," said Douglas Powell, an associate professor of food safety at Kansas State University. "But even in an outbreak situation, many students simply don't."

In February 2006, Powell and two colleagues — Ben Chapman, an assistant professor at North Carolina State University, and research assistant Brae Surgeoner — observed hand sanitation behavior during an outbreak. What was thought to have been norovirus sickened nearly 340 students at the University of Guelph in Canada.

Hand sanitation stations and informational posters were stationed at the entrance to a residence hall cafeteria, where the potential for cross-contamination was high. The researchers observed that even during a high-profile outbreak, students followed recommended hand hygiene procedures just 17 percent of the time. In a self-reported survey after the outbreak had subsided, 83 of 100 students surveyed said they always followed proper hand hygiene but estimated that less than half of their peers did the same.

The results appear in the September issue of the Journal of Environmental Health.

Powell said that in addition to providing the basic tools for hand washing – vigorous running water, soap and paper towels — college students, especially those living in residence halls, need a variety of messages and media continually encouraging them to practice good hand hygiene.

"Telling people to wash their hands or posting signs that say, 'Wash your hands' isn’t enough," said Ben Chapman, an assistant professor at North Carolina State University. "Public health officials need to be creative with their communication methods and messages."

Most students surveyed perceived at least one barrier to following recommended hand hygiene procedures. More than 90 percent cited the lack of soap, paper towels or hand sanitizer. Additional perceived barriers were the notion that hand washing causes irritation and dryness, along with just being lazy and forgetful about hand washing. Fewer than 7 percent said a lack of knowledge of the recommended hand hygiene procedures was a barrier.

"Providing more facts is not going to get students to wash their hands," Powell said. "Compelling messages using a variety of media – text messages, Facebook and traditional posters with surprising images — may increase hand washing rates and ultimately lead to fewer sick people."

Abstract
Published research on outbreaks of gastrointestinal illness has focused primarily on the results of epidemiological and clinical data collected postoutbreak; little research has been done on actual preventative practices during an outbreak. In this study, the authors observed student compliance with hand hygiene recommendations at the height of a suspected norovirus outbreak in a university residence in Ontario, Canada. Data on observed practices was compared to post-outbreak self-report surveys administered to students to examine their beliefs and perceptions about hand hygiene. Observed compliance with prescribed hand hygiene recommendations occurred 17.4% of the time. Despite knowledge of hand hygiene protocols and low compliance, 83.0% of students indicated that they practiced correct hand hygiene during the outbreak. To proactively prepare for future outbreaks, a current and thorough crisis communications and management strategy, targeted at a university student audience and supplemented with proper hand washing tools, should be enacted by residence administration.

At some point while endlessly bitching at Chapman to finish his damn thesis and produce some papers, I realized, I wasn’t so good at closing the deal myself.

I could say I like blogging, being quoted in media, the immediacy of it all, but I also realized I needed the credibility of peer-reviewed publications.

So after grappling with divorce, the angst of children lost, the joy of remarriage and once again the commitment to an ideal, another kid, I decided that while I was bitching at Chapman, I better take care of my own shop.

So, with some pride, I announce the first of about a dozen peer-reviewed papers that are going to appear this year.

Designing effective messages for microbial food safety hazards, which will appear in an upcoming issue of Food Control, by Douglas Powell, Casey Jacob and Lisa Mathiasen, was started by Lisa back in 2003. I told her it was going to be published and she said, “about time.”

Casey did some excellent improvements, and the thing is coming out.

Here’s the abstract; I’ll post the full paper info when it’s published.

Despite numerous food safety information campaigns and educational efforts, microbial foodborne illness remains a significant source of human disease. New food safety messages transmitted using new media are required to enhance food safety from farm-to-fork. A review of the literature reveals that targeting a segment of the population and understanding knowledge, attitudes, and perceptions of the individuals comprising that segment can lead to successful communication of food safety messages. Messages found to be effective are relevant to the target audience, contain reliable information, are rapidly distributed at appropriate times, and are repeated. Those containing information that is easily received and understood have also been found effective. The use of media commonly accessed by today’s consumers is also valuable. Evaluation of the effect of all aspects of food safety messages and media, as measured through observation of recipients’ actions, is required to validate the effectiveness of food safety communications.

And I’m in love with my partner, cause she’s the meanest editor I’ve ever had.

And vice-versa.
