Salad-bar syndrome: It sounds slightly ridiculous, no? Is it the sinking dread that visits salad-bar grazers as they stare listlessly into the bar, overwhelmed by choices? — chick peas and carrots and corn, oh my! Or could it be a nasty foodborne illness transmitted through super-powered sneezes that blast right past the plastic guard?
When Hinesburg resident Wright Cronin told Seven Days that his doctor recently suggested he might be suffering from SBS, we just had to get to the bottom of it. WTF is it? Is it as silly as it sounds? And how does one get it?
“It might mean different things to different people,” says Dr. William Newman of Allergy & Asthma Specialists of Northern Vermont in Essex. But, he insists, there’s at least one legitimate condition that goes by the name salad-bar syndrome — and it all comes down to sulfites.
Many people are sensitive to sulfites, preservatives with antioxidant and antibacterial properties, the doctor told us. They’re commonly found in beer and wine, medications, packaged dried fruit, and nuts. And, because sulfites keep veggies from turning brown, they’re sometimes found in salad bars.
“There is definitely an effort to make that lettuce look appealing even if it’s been out there for a few hours,” Newman says. It’s not uncommon, he adds, for restaurants or grocery stores with salad bars to spray their raw produce with a sulfite preservative. “You can see why they’d want to do it, but they may not disclose this.”
Seven Days called area businesses with salad bars to find out if anyone was spraying with sulfites. Prepared-foods manager Adam Pheiffer at City Market said that store doesn’t spray anything on its veggies. “Food comes in, we wash it off and put it on the salad bar,” he said.
At the South Burlington Price Chopper, a deli manager said, “We don’t put anything on our salad bar. But our lettuce and stuff comes in a bag, so I don’t know if something has been sprayed on it before it comes to us.”
The U.S. Food and Drug Administration, U.S. Department of Agriculture, and Bureau of Alcohol, Tobacco and Firearms all regulate the use of sulfites in packaged foods, which is why you’ll often see the phrase “contains sulfites” on wine labels and bacon packaging. While the FDA has prohibited the use of sulfites to maintain the color and crispness of fresh fruits and veggies in salad bars since 1986, Newman says food services sometimes still use their own spray. “It’s not like it’s a hard thing to find,” he says.
According to a 2011 University of Florida study, the FDA regulations don’t require managers of food-service establishments to disclose to consumers if they’ve used sulfites. “Consumers should therefore be careful and not expect the waitstaff at restaurants to know this information, as erroneous information may be given,” the study concludes.
For most people, ingesting sulfites is nothing to worry about. But in some folks, especially those with asthma, the preservatives can cause a kind of allergic reaction — a cough, phlegm or blockage of the airway. “Ingestion [of sulfites] liberates sulfur dioxide, and that can be a trigger for asthma,” explains Newman. “It’s really no different from an asthmatic having exposure to other things that flare asthma — attending the Olympics in Beijing, or getting the flu, or being allergic to the cat that was just acquired as a pet.”
Cronin, a 31-year-old psychotherapist, has asthma. He doesn’t drink, so he hasn’t experienced any sulfite sensitivity from beer or wine. “I talk for a living,” he says. So he was acutely aware of the scratchiness in his voice and the cough that developed each time he ate lunch from his favorite local salad bar. “It would last for an hour or so,” he says. “I started to think I was allergic to raw veggies.”
The symptoms were persistent enough that the next time Cronin went to the doctor, he brought it up. That’s when his doc suggested he might be suffering from SBS.
“It seemed unique and funny to me,” Cronin says. “But there’s a part of me that kind of loves shit like that.”
So he took the physician’s diagnosis to heart. He stopped visiting the salad bar — and, sure enough, he’s been cough and phlegm-free ever since.

What a pleasure salad bars have been since the sulfite spraying has stopped. Lettuce and potatoes were the ones that got me severely. At a doctors recommendation I began carrying Benadryl with me at all times while the preservative was still in use. I finally got where I could detect it on lettuce as a slight nutty flavor but I never could detect it on potatoes. Fortunately they banned the stuff and I have no more problems. The sulfites in beer, wine and flu shots have no effect on me, it was just the massive dose from the food.
My dad & brother both get instant diarrhea & intestinal distress if they eat lettuce from a restaurant. It’s happened enough times to know that’s definitely the cause, and it sets in so quickly that it can’t possibly be a stomach virus or something picked up from contaminated salad because those things take time to incubate before causing illness. My mom can eat the exact same thing & be fine. These are huge dudes who eat everything you put in front of them but lettuce scares them to death, lol. So I’m guessing a lot of restaurants still use this crap on their salad.
Eating food raw is a bad idea in general, whether it’s oysters, lettuce, sushi or fruit. Uncooked food is more likely to contain harmful bacteria or viruses that can cause gastroenteritis. Cooking at least provides some protection against these pathogens.
Raw foods are the best for us. Veggies anyway…
We don’t eat out very often, but we’ve figured out that when we go to chain restaurants or other places that use lots of fresh vegetables for things like salad bars and sandwiches, my husband gets horrible intestinal distress that lasts for several hours. If he prepares and eats the same things at home, no problem. We’ve also found that small, local restaurant salads and such don’t seem to cause the problem. I’m guessing that maybe they don’t buy pre-shredded lettuce and such in bulk and hence it stays fresh without them treating it with anything. I can eat the exact same thing he does and I’m fine. We’ve had it happen at pizza chains with veggie pizza, sandwich places with veggie sandwiches, taco places that use bagged shredded lettuce, etc. If we have the same things at a little mom-and-pop type place, it doesn’t happen. Yet another reason to eat local, I suppose.
