Botulism, a food-borne toxin-mediated disease caused by Clostridium bo
tulinum is still a common disease, which is most frequent in the rural
environment; 108 cases, 66 males and 42 females, average age 32 years
, were recorded from 1965 to 1990 in the infectious disease department
of the University Hospital of Poitiers (France). In 83 % of patients,
the food responsible was home-cured ham. Mean incubation time was 34
days; digestive symptoms were observed in 93 % of cases, ocular sympto
ms in 99% and urinary tract dysfunction in 22 % A scale of severity wa

intermediate (50) and mild (52) forms of the disease. Botulinum toxin
type B was found in 36 (52 %) of 69 blood samples and in 41 (51 %) of
81 samples of the suspected food. From 1965 to 1976, 44 patients were
treated with both toroid and heterologous equine serotherapy. Since 19
