Rat poison? From China:

BEIJING, April 10 (Reuters) - One person died and more than 200 fell ill after eating breakfast porridge suspected of containing rat poison at a hospital in China, state media said on Tuesday.

Patients and staff at a traditional Chinese hospital in the northeastern city of Harbin suffered nausea and diarrhoea shortly after eating breakfast at its restaurant on Monday, Xinhua news agency said.

"All the victims ate porridge, and investigators suspected the water had been contaminated by rat poison," Xinhua said.

Du Qingrong, a 77-year-old woman admitted on Friday for cardiovascular disease, died on Monday afternoon.

All other victims were out of danger by Monday afternoon, Xinhua said, citing hospital sources.

The news agency said the hospital, one of Heilongjiang province's largest and best-equipped medical institutions, had been shut down after the incident and food samples taken for testing.
