Health officials in Taiwan have confiscated nearly 500 kilograms of tainted duck blood products which contain metallic bio-toxins.
The duck blood was produced by a company called Shuang Peng Foods.
The products were being sold in retail outlets across the island, including in over 100 Noble Family stores.
Noble Family, one of the largest retail chains on Taiwan, has since taken all duck blood products off the shelves.
"We do not sell food made with duck blood now, because it might have been polluted. So, all our duck blood-related products are off the table now."
Local authorities say if any restaurant or vendor is found selling contaminated duck blood, they will face fines of up to 100-thousand US dollars.
