The Macao agent of a Taiwan-made energy drink branded "Bullwild" has announced a total recall of the goods due to poison scare, local media reported Thursday.

The Macau Post quoted sources from Bullwild's Macao company as saying that there are 2,640 bottles of the beverage on sale or in stock and the recall will be completed within one day.

Bullwild's Taiwan company launched an emergency recall of the beverage earlier this week after four people were reportedly poisoned by the product on the island.

Police suspect that someone laced the drink with cyanide before placing it on store shelves, Taiwan media reported.
