SummaryTwo hundred and fifty bee keepers in the South of France, working seasonally, were clinically investigated by means of a questionnaire. Forty‐three percent had presented anaphylactic symptoms and 7.0, toxic reactions when stung by bees. The personal atopic history was found to be significantly (P<0.01) elevated in bee keepers who experienced anaphylaxis. Total serum IgE and bee venom‐specific IgE were titrated in 100 subjects. Total serum IgE was significantly elevated in allergic bee keepers (P= 0.02). Although bee venom‐specific IgE were significantly (P<0.01) higher in allergic bee keepers this parameter cannot discriminate between allergic and non‐allergic bee keepers owing to a considerable overlap. Bee venom‐specific IgG was assayed in seventy subjects. Their level was significantly (P<0.001) higher in allergic and non‐allergic bee keepers as compared with non‐allergic blood donors and non‐bee‐keeping allergic patients. In both bee keeper groups there was no difference in bee venom‐
