Sec. 185.4900   Piperonyl butoxide.

    The food additive piperonyl butoxide may be safely used in 
accordance with the following prescribed conditions:
    (a) It is used or intended for use in combination with pyrethrins 
for control of insects:
    (1) In cereal grain mills and in storage areas for milled cereal 
grain products, whereby the amount of piperonyl butoxide is at least 
equal to but not more than 10 times the amount of pyrethrins in the 
formulation.
    (2) On the outer ply of multiwall paper bags of 50 pounds or more 
capacity in amounts not exceeding 60 milligrams per square foot, whereby 
the amount of piperonyl butoxide is equal to 10 times the amount of 
pyrethrins in the formulation. Such treated bags are to be used only for 
dried foods.
    (3) On cotton bags of 50 pounds or more capacity in amounts not 
exceeding 55 milligrams per square foot of cloth, whereby the amount of 
piperonyl butoxide is equal to 10 times the amount of pyrethrins in the 
formulation. Such treated bags are constructed

with waxed paper liners and are to be used only for dried foods that 
contain 4 percent fat or less.
    (4) In two-ply bags consisting of cellophane/polyolefin sheets bound 
together by an adhesive layer when it is incorporated in the adhesive. 
The treated sheets shall contain not more than 50 milligrams of 
piperonyl butoxide per square foot (538 milligrams per square meter). 
Such treated bags are to be used only for packaging prunes, raisins, and 
other dried fruits and are to have a maximum ratio of 3.12 milligrams of 
piperonyl butoxide per ounce of fruit (0.10 milligram of piperonyl 
butoxide per gram of product).
    (5) In food processing and food storage areas: Provided, That the 
food is removed or covered prior to such use.
    (b) It is used or intended for use in combination with pyrethrins 
and N-octylbicycloheptene dicarboximide for insect control in accordance 
with Sec. 178.3730.
    (c) A tolerance of 10 parts per million is established for residues 
of piperonyl butoxide in or on:
    (1) Milled fractions derived from cereal grains when present therein 
as a result of its use in cereal grain mills and in storage areas for 
milled cereal grain products.
    (2) Dried foods when present as a result of migration from its use 
on the outer ply of multiwall paper bags of 50 pounds or more capacity.
    (3) Foods treated in accordance with Sec. 178.3730.
    (4) Dried foods that contain 4 percent fat, or less, when present as 
a result of migration from its use on the cloth of cotton bags of 50 
pounds or more capacity constructed with waxed paper liners.
    (5) Foods treated in accordance with paragraph (a)(4) and (5) of 
this section.
    (d) To assure safe use of the additive, its label and labeling shall 
conform to that registered with the U.S. Environmental Protection 
Agency, and it shall be used in accordance with such label and labeling.
    (e) Where tolerances are established under sections 408 and 409 of 
the Act on both raw agricultural commodities and processed foods made 
therefrom, the total residues of piperonyl butoxide in or on the 
processed food shall not be greater than that permitted by the larger of 
the two tolerances.
