New Hampshire Restaurants Step Up Safety Measures as Cyclospora Cases Rise

When you walk into a New Hampshire diner these days, you might notice a few extra steps behind the counter – not because the kitchen is getting fussy, but because the state health department is keeping a close eye on a pesky parasite called cyclospora.

As of July 21, 2026, the New Hampshire Department of Health and Human Services says six people have tested positive for the parasite. That number sounds small, but remember the state usually sees fewer than ten cases a year, so it’s enough to raise eyebrows.

“We do not believe that any of our cases have a linkage to the current outbreak that’s happening in the Midwest,” explained Colleen Smith, the department’s spokesperson. The Midwest outbreak, she added, remains separate – there’s no confirmed connection to the New Hampshire cases.

Doctors are urging residents to wash fruits and veggies at home and to buy produce from sources they trust. “If you’re buying packaged lettuce, give it a quick rinse. And if you’re cooking, be sure your water’s hot enough,” said Dr. Brett Sweeney of Southern New Hampshire Health.

Local restaurants are taking the advice to heart. The Common Man – the family‑owned chain that runs the Airport Diner and 18 other spots across the state – says its salads are still on the menu, but they’re being handled with extra vigilance.

“We’re not connected to the outbreak at all,” said Nicole White, the culinary director for The Common Man. “Our lettuce comes from farms right here in New England, and we’ve got a digital vendor‑alert system that pings us by text the moment a recall happens.”

That system, White explained, lets the chain act fast if a supplier ever gets a recall notice. So far, no alerts have triggered a menu change, and the restaurants continue to serve fresh greens without pause.

Outside of New Hampshire, the broader investigation still centers on a large lettuce supplier, Taylor Farms. Recent testing on its product turned out to be a false positive, but the agency’s eyes remain on the company.

For diners, the takeaway is simple: enjoy your salad, just give it a good wash at home if you can, and know that local eateries are double‑checking their produce streams. As the health department monitors the situation, New Hampshire’s food scene seems ready to keep serving up flavor — safely.
