Taiwanese french fry suppliers to be checked amid food concerns

Taiwan’s health authorities will conduct stringent checks of potato suppliers after reports that French fries served at fast food restaurants were found with green patches. Food and Drug Administration (FDA) official Cheng Wei-chih said that potatoes can turn green due to exposure to enough light. However, consuming a large amount of green potato can cause nausea, vomiting, and diarrhea as it often contains a toxic chemical called solanine. No regulations regarding the maximum level of solanine are imposed yet, Cheng added. The scoop of green-tinted potatoes was first posted online by a user of PTT, the largest terminal-based bulletin board system (BBS) in Taiwan. He wrote that his tongue felt weird when he was eating potato wedges at McDonald’s and he found there was a green tint in the food. McDonald’s later responded that the company has adopted strict control measures requiring suppliers and workers to remove green potatoes.
