Are shared fryers really off-limits for people with celiac disease?

https://www.news-medical.net/news/20261022/Are-shared-fryers-really-off-limits-for-people-with-celiac-disease.aspx French fries and tortilla chips cooked alongside gluten-containing foods may not always pose the risk previously assumed, as new research finds that most samples contained low gluten levels, with fryer oil changes emerging as a potentially important factor. People with celiac disease are commonly advised to avoid foods prepared in fryers also used for gluten-containing foods. However, a recent study published in Nutrients found that most French fries and tortilla chips prepared in shared fryers contained gluten levels below the US regulatory threshold for gluten-free labeling, suggesting that contamination risk may be lower than commonly assumed in some food-service settings.
