  1. Interregional foodborne salmonellosis outbreak due to powdered infant formula contaminated with lactose-fermenting Salmonella virchow.

    Article - En anglais

    Spain's Salmonella surveillance system backed by regionally-based epidemiologists around the country made it possible to detect and halt the spread of a foodborne salmonellosis outbreak due to powdered infant formula contaminated with a lactose-fermenting strain of Salmonella virchow.

    Forty-eight cases involving children, mostly under 7 months old, were detected in 14 out of Spain's 17 Regions.

    The outbreak started in January and ended in June 1994.

    All cases were microbiologically confirmed.

    The implicated strain had a 3.6 kb plasmid, was susceptible to all antimicrobials tested except nitrofurantoin and was phagetype 4a.

    Isolates from 8 of 24 Brand « A » milk samples tested had the same characteristics as case isolates.

    All affected/suspect batches of Brand « A » milk were destroyed and the product withdrawn from sale, which led to the end of the outbreak.

    This incident underscores the importance of maintaining surveillance systems able to detect and prevent foodborne outbreaks and alert to the possibility of isolating unusual lactose-fermenting Salmonella serotypes in especially sensitive food products.
