Summary
The findings, originally reported in April 2024, involved mushrooms produced domestically and imported from China. Although the small sample does not establish how widespread contamination is, recent overseas recalls show that the food safety risk remains relevant.
Enoki mushrooms, known locally as hed khem thong, are widely used in Thai hotpot dishes, shabu-shabu, sukiyaki, stir-fries and grilled foods.
