More than 99 percent of the freshwater products in Shanghai have passed inspections and are safe to eat, the local food safety authorities said yesterday. The only fish on the exception list are turbots.

Hong Kong found malachite green, a cancer-causing chemical, in mud carp imported from Shunde, Guangdong Province last week. Fish vendors in Hong Kong have suspended the sale of more than 30 types of freshwater products from the Chinese mainland, including the popular mandarin fish.

Since last year, Shanghai's food safety watchdog has established 79 inspection services citywide, with more than 60 focusing on residual antibiotics in 50-plus edible aquatic products.
