The annual reported totals of cases of listeriosis in England, Wales and Northern Ireland have remained low over the last three years and a total of 108 cases was reported in 1992. The clinical and epidemiological features reported in 1992 were similar to those in previous years and in other countries, except for a shift in the seasonal peak to the summer (a pattern consistently seen before the upsurge in 1987) and a reduction in the case fatality rate of non pregnancy-associated cases.
