The Health Bureau of Taichung City Government implemented food safety checks recently and found 13 out of 322 products to be violating regulations.

Ahead of Chinese New Year, the city’s health authorities have stepped up inspections on traditional holiday food products.

The Health Bureau announced that it found 13 products – including duck blood, noodles and snow fungus – that violated food safety regulations.

Health officials also found pepper powder made from non-food grade magnesium carbonate; tea leaves that contained pesticide residue; and steamed spring roll that contained rongalite, a banned bleaching agent.

All products were either taken off the shelf right away or destroyed, according to the local health bureau.
