Singapore has prohibited food products made from animal blood, including pork, due to potential health risks. This decision was enforced after a investigation revealed a Thai restaurant was selling pork blood dishes. The Singapore Food Agency warned that unhygienic drawing of blood can lead to food-borne pathogens. The import and sale of such products can result in significant fines or imprisonment. In other news, the World Health Organization has formed a advisory group to study the origins of the coronavirus and prepare for possible outbreaks of Disease X, a term for an unidentified virus. The Nipah virus outbreak in 1999, which originated from pigs in Malaysia, was cited as an example of a zoonotic disease.
