АНУ-д энэ онд бохирдсон салатны ногооноос шалтгаалан циклоспориаз өвчний тархалт нэмэгдэж, иргэдийн эрүүл мэндэд эрсдэл учруулаад байна.
Америкийн Нэгдсэн Улсад энэ онд бүртгэгдсэн циклоспориазын дэгдэлт нь бохирдсон салатны ногоотой холбоотой болохыг холбогдох албаныхан тогтоожээ. Уг халдварт өвчин нь суулгалт, бөөлжилт, шингэн алдалт зэрэг шинж тэмдгээр илэрдэг байна. АНУ-д 2018 онд McDonald’s-ийн салатаар дамжин 16 мужийн 500 гаруй хүн, 2020 онд Fresh Express-ийн салатны багцаар дамжин 700 гаруй хүн тус тус өвчилж байсан удаатай.
Мэргэжилтнүүдийн үзэж буйгаар салатны ногоо нь хөрсөнд ойр ургадаг тул бохирдсон усаар услах үед шимэгч хорхой, бактериар бохирдох эрсдэл өндөр байдаг аж. Түүнчлэн ногооны навчны завсраар нян нэвтрэн орох боломжтой бөгөөд угааж цэвэрлэхэд хүндрэлтэй байдаг нь халдвар тархах гол шалтгаан болж байна.
Циклоспора шимэгчийг устгахын тулд ногоог 158 хэм хүртэл халаах шаардлагатай байдаг тул түүхийгээр нь хэрэглэх нь эрсдэлийг нэмэгдүүлдэг. Одоогийн байдлаар яншуй, кинза зэрэг ногоо ч мөн халдварын эх үүсвэр болж болзошгүй байгааг Хоол хүнсний аюулгүй байдлын агентлаг анхааруулж байна.

Contaminated lettuce has been linked to widespread outbreaks of cyclosporiasis in the U.S. this year, an illness that leads to explosive diarrhea, vomiting and dehydration.
This isn’t the first time lettuce has been implicated. In 2018, an outbreak linked to McDonald’s salads sickened more than 500 Americans across 16 states, federal data shows. Two years later, an outbreak tied to Fresh Express’s bagged salad affected more than 700 people, and a 2022 outbreak was traced to Caesar salad kits.
Lettuce has also been tied to E. coli and Salmonella outbreaks.
So, why is the leafy green such a common culprit of foodborne illnesses? For one, we eat a lot of it. Americans consume an average of 25 pounds of lettuce annually.

Secondly, lettuce is hard to wash, which can leave you susceptible to any hitchhiking bacteria or parasite. “If you don’t wash these products well, you’re going to end up ingesting whatever is on the lettuce,” Amira Roess, an epidemiologist at George Mason University, told WIRED.
Bacteria and parasites can hide deep in crevices between lettuce leaves, and it doesn’t help that lettuce grows close to the soil, either. The closer fresh produce is to soil, the more likely it is to come into contact with contaminated water that can spread the cyclospora parasite widely.
Contaminated water is the likely source of most big outbreaks, including this one, experts told The New York Times last week.

“You’d have to have a lot of produce being irrigated with a lot of water that was contaminated by a lot of cyclospora to see this number of cases,” Keith Schneider, a professor of food safety at the University of Florida, said.
Because of lettuce leaves’ tough yet fragile exterior, it can be harder to clean than smooth-skinned produce.

Broken leaves are also a problem, Barbara Kowalcyk, director of the Institute of Food Safety and Nutrition Security at George Washington University, told TIME.
She explained that it’s “how the bacteria gets inside.”
Relying on pre-washed lettuce is not necessarily safe, either as it may not remove microbes clinging to the leaves, the University of Connecticut Extension said.
Lastly, we eat lettuce raw on sandwiches and in salads. That’s a big part of the problem. Heating produce to a temperature of 158 degrees Fahrenheit is the only thing that kills the cyclospora parasite.

Cooking can also be effective against some strains of Salmonella and E. coli, if done right.
Parsley and cilantro are reportedly tied to recentcyclospora cases in North Carolina, according to the New York Post. Herbs have a lot of the same problems lettuce does. We eat them raw, they grow close to the ground and they’re often tough to clean.
“Because these herbs may commonly be consumed without washing or a ‘kill-step,’ such as cooking, there may be an increased risk of human illness if microbial hazards are present,” the FDA warns.
The best case might be avoiding these potentially contaminated foods for the the time being.
“People often laugh when they hear the phrase ‘explosive diarrhea,’ but for the individuals experiencing it, there’s nothing humorous about it,” Darin Detwiler, a professor emeritus at Northeastern University, told Serious Eats.
“Behind every reported case is a person whose life has been unexpectedly interrupted simply because they ate food they believed was safe.”
