Rat poison mixed in school meals

Police say a cook has confessed to placing rat poison in meals served in a public-school cafeteria in southern Brazil. Police inspector Cleber Santos de Lima tells the Globo television network's G1 website that 22 students and 16 teachers and employees of the Pacheco Prates school fell ill in the city of Porto Alegre after eating beef stroganoff. He says all were treated in a local hospital and released. He says police were called when open packages of rat poison were found in the school kitchen. Police questioned cafeteria employees, and one of the cooks confessed to lacing the stroganoff with rat poison. Lima says the cook was unable to explain why she poisoned the meals.
