A contaminated salad containing duck meat is suspected of having killed five residents of a care home for the elderly in southern France. Four women and a man, aged from 76 to 95, died after eating the salad on Sunday night. In all, 20 people at the home near Toulouse suffered vomiting and other symptoms of food poisoning. Twelve of those taken ill are in hospital, but not in grave danger. The salad ingredients, including duck foie gras (pâté), are being examined.
