KRASNOYARSK, June 20 (RIA Novosti) - A court in East Siberia's city of Krasnoyarsk passed sentences on two people found guilty of poisoning 287 people at a governor's ball in March this year.

The court fined Oksana Gegel, a chef at the Caterier company, which supplied the food for the ball, 30,000 rubles ($1,160), and banned Pavel Ponomaryov, the director of the Caterier, from working in the catering trade for 21 months.

They were both accused of breaching food safety standards whilst preparing dishes for the IQ Ball, which led to 287 people being hospitalized with salmonella poisoning.

The ball, thrown by Krasnoyarsk Governor Alexander Khloponin March 1, was attended by almost 1,500 people. Of those who fell ill, most were poisoned by eating contaminated sandwiches.

An investigation into the case revealed that Caterier, which prepared salads and hors d'oeuvres for the ball, did not have a permit to handle food.
