International epidemiological and microbiological study of outbreak of Salmonella agona infection from a ready to eat savoury snack—I: England and Wales and the United States

Rapid international exchanges of information led to the identification of the source of a major outbreak of S agona in Israel and of associated cases in North America. The outbreak showed the value of the Salm-Net surveillance system and its links outside Europe, both for increasing case ascertainment and for improving the information on the duration of the fault at the manufacturing plant.
