A recent study conducted at the North Carolina State University found that restaurants don't perform an effective job of communicating with customers when it comes to addressing risks associated with eating undercooked meat - specifically hamburgers.
Published in the Journal of Food Protection, the study also found that inaccurate information provided by servers often contradicts science-based information customers need to make informed food safety decisions.
All 50 states in the U.S. have adopted some version of the Food & Drug Administration's Model Food Code, which requires restaurants to tell customers about risks associated with undercooked meat and poultry products.
"We wanted to know how well restaurant servers and menus communicated with customers about these risks, specifically in the context of beef hamburgers," said Ben Chapman, co-author of a study.
The researchers focused on beef hamburgers because consuming undercooked ground beef has been linked to a lot of foodborne illness outbreaks, including outbreaks related primarily to Shiga toxin-producing E. coli.
For this study, the researchers sent trained "secret shoppers" into 265 full-service, sit-down restaurants in seven different regions around the U.S. At each restaurant, the patrons ordered one well-done hamburger and one medium-rare hamburger to go.
The shoppers then recorded how, if at all, the restaurant communicated about risk.
This study is the latest in a long line of real-world research that Chapman and his collaborators have conducted.
"We try to actually match what people do versus what they say they do because people will say anything on a survey," Chapman said.
Adding, "We've looked at cooking shows; observed handwashing and cross-contamination in commercial kitchens; examined hand hygiene during a norovirus outbreaks and others. What people actually do is the difference between an enjoyable meal and a foodborne illness.
"For example, did the server mention risks associated with undercooked meat when the shopper ordered? If not, the shopper would ask about the risk of getting sick, and then record whether the wait staff responded with clear, accurate information," he said.
The shoppers also looked to see whether restaurants included clear, accurate risk information on their menus.
The study found that 25 percent of restaurants wouldn't even sell an undercooked hamburger to secret shoppers.
However, at restaurants that would sell a medium-rare hamburger, the majority of servers - 77 percent - gave customers unreliable information about food safety.
"Servers said that meat was safe because it was cooked until 'until the juices ran clear' - which is totally unreliable," said Ellen Thomas, the lead author of the study .
Adding, "Those 77 percent didn't mention things like cooking meat to the appropriate temperature - either 155°F for 15 seconds, or 160°F for instant kill. The indicator of safety most widely reported by servers was the color of the burger, and that's also not a reliable indicator at all," Thomas says "Time and temperature are all that matter. An undercooked, unsafe burger can be brown in the middle, and a safely cooked burger can still be red or pink in the center."
Meanwhile, almost all of the menus complied with FDA guidance. But what servers told customers often contradicted the information on the menu.
"If a menu says something is risky but a server says that it isn't, that can downplay the risks for consumers and impact a customer's decisions. It's confusing, leaving the patron to choose which message to believe," Chapman said.
The researchers also found that chain restaurants fared much better than independent restaurants at having servers offer reliable risk information.
"That's not surprising. Large chains implement standardized training across all outlets for servers in order to protect their brand and reduce the likelihood of being implicated in a foodborne illness outbreak. That's bad for business," he said.
Adding, "This study tells us that servers aren't good risk communicators. We encourage consumers to ask food-safety questions, but they should probably ask a manager," he concluded.
