Hygienic Study on Allergic Contact Dermatitis in Chrysanthemum Growers / 日本農村医学会雑誌

ABSTRACT

A questionnaire survey and patch testing on skin disorders were conducted on 20 chrysanthemum growers (15 males and 5 females) in the Kohoku district of Shiga Prefecture in order to clarify the etiology and make a plan for prevention. The results were as follows;<BR>1) Thirteen subjects suffered from skin disorders and 8 of them had contacted dermatitis since they started the cultivation of chrysanthemum.<BR>2) It was suggested that the skin disorders might be associated with such types of work as “lower -leaves pruning, ” “harvesting” and “shipping, ” during which they were closely in contact with chrysanthemum. However, our survey found that most the subjects paid less attention to chrysanthemum than pesticides to prevent skin disorders.<BR>3) The patch test found 10 out of the 13 subjects who had suffered from skin disorders manifested sensitization reactions to chrysanthemum or pesticides and 7 of them to both.<BR>Dermatologically, the disorders were diagnosed as allergic contact dermatitis caused by chrythanthemum or pesticides, but it was difficult to clarify which was the main factor of contact dermatitis.<BR>4) In order to prevent contact dermatitis among chrythanthemum growers, hygienic education on the sensitizing activity of chrysanthemum and guidance on effective protection against chrysanthemum and pesticides are needed.
