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
[[Page 505]]
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.
