"We are investigating the matter with the relevant authorities and reinforcing hygiene practices."

The Straits Times newspaper said the cyclists were staying at Resorts World Sentosa, a hotel, casino and funpark complex popular with tourists.

Malaysian rider Muhammad Fauzan Ahmad Lutfi blamed his dinner of chicken and curry egg for his performance after he finished 11th in the men's time trial.

"Two other riders, including my room-mate, are down too. I think it was the chicken and the curry egg at dinner. I felt sick at around 1am last night," he said.

The incident follows a food poisoning outbreak at the 2010 Youth Olympic Games in Singapore, which affected more than 20 people working for the organising committee.(+++)
