Bleeding problems associated with occupational exposure to anticoagulant rodenticides.

OBJECTIVE

Sporadic reports have occurred on adverse health effects due to occupational exposure to anticoagulant rodenticides. We report a case of coagulation derangement in a pest-control officer and present the results of a survey of his colleagues.

METHODS AND

RESULTS

A 48-year-old man worked as a part-time pest-control officer applying rodenticides 3 h a week using gloves, but no mask, and without washing his hands between applications. He developed a symptomatic coagulation disturbance, probably caused by absorption of the poisons during work. No signs of coagulopathy were found in the patient's colleagues ( n=16), although basic hygiene measures were not always taken.

CONCLUSION

Occupational exposure to anticoagulants should be considered in cases of unexplained bleeding. We recommend that measures be taken to minimize the risk of occupational intoxication.
