Objectives-To identify the source of an international outbreak of food poisoning due to Salmonella agona phage type 15 and to measure how long the underlying cause persisted.
Design-Case-control study of 16 primary household cases and 32 controls of similar age and dietary habit.
Packets of the implicated foodstuff manufactured on a range of days were examined for salmonella.
All isolates of the epidemic phage type were further characterised by pulsed field gel electrophoresis.
27 cases were identified, of which 26 were in children.
The case-control study showed a strong association between infection with S agona phage type 15 and consumption of a peanut flavoured ready to eat kosher savoury snack imported from Israel.
S agona phage type 15 was isolated from samples of this snack.
The combined food sampling results from the United Kingdom, Canada, the United States, and Israel showed that contaminated snacks were manufactured on at least seven separate dates during a four month period between October 1994 and February 1995.
Voluntary recalls of the product successfully interrupted transmission.
Conclusions-Rapid international exchanges of information led to the identification of the source ofa major outbreak of S agona in Israel and of associated cases in North America. (...)
