Anthrax in England and Wales 1963-1972.

The records of confirmed anthrax diagnoses held by the bacteriology department of the Central Veterinary Laboratory, Weybridge, for the years 1963 to 1972 inclusive, were analysed. During this decade, 86 per cent of the 2944 deaths recorded were in cattle and 11 per cent in pigs, correlating significantly with the cattle and pig populations in England and Wales during this period. Also, the country could be separated into high and low prevalence counties for cattle anthrax. Norfolk and Somerset had higher than usual cattle deaths per farm ratios and the reasons for this are explored.
