Abstract For over a century, the British government has pursued a policy of national freedom from foot and mouth disease (F.M.D.), a highly contagious disease of cloven-footed animals. One of the cornerstones of this policy was the slaughter of infected animals. However, on several occasions – most notably in 2001 – slaughter struggled to contain F.M.D., and provoked widespread criticism and calls for policy change. Drawing upon a range of previously unexamined sources, this article examines the history of F.M.D. in Britain, in an attempt to explain the twenty-first-century persistence of a Victorian disease control policy.

SUMMARYStudies were carried out in South America to assess the effect of maternally derived antibody (MDA) on the responsiveness of calves to FMD vaccination. It was found that calves with MDA did not merely fail to respond to vaccination, but that their serum titres were depressed. This depression was proportional to the level of pre-existing MDA at the time of vaccination and following primary vaccination it persisted for a least 60 days. High MDA titres interfered with both primary and secondary responses. Animals with relatively low MDA titres were able to respond to vaccination, or at least to be sensitized so that on revaccination they showed a satisfactory response. The half-life of MDA was shown to be approximately 22 days, suggesting that under field conditions significant MDA titres are likely to persist for 4–5 months. A trial carried out in Brazil in which the primary course of two inoculations, 4 weeks apart, was initiated when the calves were 5–6 months of age, resulted in the reduction of FMD in the calf population from 11% to 0·9% over a 12-month period. The use of vaccination programmes of this type to lessen the incidence of FMD in young bovines is discussed.
