Residual sprays such as chlordan and D D T are needed i n the production of bakery goods and are an essential factor i n the production of these goods free of insect sources of filth. However, there is no need to establish a tolerance or acceptance of any amount of D D T i n bakery goods. N o residual sprays are to be employed i n any way i n any area where they could contaminate either ingredients or the finished product. This is i n contrast to the agricultural uses of these products, where they are necessarily incorporated i n a slight degree i n the finished product.
A definite concentration must result i n vital tissues before irreversible toxic effects occur. The most effective method of treating poisoning is to prevent its occurrence. This having failed, the sine qua non is removal of the unabsorbed portion, or alteration chemically or physically so that the absorbed portion does not remain i n contact with cells i n toxic amounts. Unfortunately, most of the antidotal treatment of poisoning from agents of economic importance is symptomatic—that is, physiologic i n nature.

This paper presents information on six materials related to piperonyl butoxide, tested in combination with pyrethrins. W o r l d food shortages lend added weight to the importance of safe insecticides.
