Jack in the Box officials blamed a food poisoning outbreak that led to one death and the hospitalization of at least 70 persons from Seattle to San Diego on a shipment of contaminated hamburgers traced to Arcadia-based Vons. Vons has denied its meat processing plant in El Monte was the source of the problem.
Jack in the Box announced it will no longer buy hamburger patties from Vons. This comes a week after a severe food poisoning outbreak linked to Jack in the Box left 2 children dead and at least 75 people hospitalized.
