Insecticidal lacquers containing dieldrin emit a toxic vapour which passses through jute sacking and kraft paper, and is readily absorbed by flour. Dieldrin contamination can persist in flour stored in open‐topped containers for 18 months, and can be produced by as little as 3 h. contact with the lacquer. Samples of flour which had been in contact with an endrin lacquer in one flour mill contained up to 323 p.p.m. of endrin, which is more than twice the concentration known to cause symptoms of acute toxic poisoning in man.
