On September 21, 2026, Khaosod Online reported that a 20-year-old security guard living near Maejo University in Chiang Mai filed a complaint regarding a food safety incident. The individual purchased a bag of 'stir-fried clams with chili' for 60 baht from a local market stall on the evening of September 19.
According to the report, the consumer discovered that the clam shells were filled with mud and clay after consuming a portion of the meal. Shortly thereafter, the individual experienced severe diarrhea that persisted for three days.
