This is from the EPA on tolerance levels in certain crops. I am having trouble figuring out if our Oats (recleaned or steam rolled) are under the 1.0 ppm or the .05 ppm levels. Out product is used for feed. The chemical in question is Deltamethrin. Help please! 

 

(2) A tolerance of 0.05 ppm is established for residues of the insecticide deltamethrin, including its metabolites and degradates, in or on all food/feed items (other than those covered by a higher tolerance as a result of use on growing crops) when deltamethrin is used in food/feed handling establishments or as a wide-area mosquito adulticide. Compliance with the tolerance levels specified is to be determined by measuring only deltamethrin,

 

But in the table before it says the following (we fall in the crop group 15):

 

§180.435   Deltamethrin; tolerances for residues.

(a) General. (1) Tolerances are established for residues of deltamethrin, including its metabolites and degradates, in or on the commodities listed in the following table. Compliance with the tolerance levels specified is to be determined by measuring only deltamethrin, (1R,3R)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylic acid (S)-alpha-cyano-3-phenoxybenzyl ester, and its major metabolites, trans-deltamethrin, (S)-alpha-cyano-m-phenoxybenzyl(1R,3S)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylate, and alpha-R-deltamethrin, ®-alpha-cyano-m-phenoxybenzyl-(1R,3R)-3-(2,2-dibromovinyl)-2,2-dimethylcyclopropanecarboxylate, in or on the commodity.

 

Commodity        Parts per million

Almond, hulls    2.5

Apple, wet pomace        1.0

Artichoke, globe               0.5

Barley, bran        5.0

Cattle, fat            0.05

Cattle, meat       0.02

Cattle, meat byproducts               0.05

Citrus, dried pulp*           3.0

Citrus, oil*           50

Corn, field, forage           0.7

Corn, field, refined oil    2.5

Corn, field, stover            5.0

Corn, pop, stover             5.0

Corn, sweet, forage        10

Corn, sweet, kernel plus cob with husks removed            0.03

Corn, sweet, stover        15

Cotton, refined oil           0.2

Cotton, undelinted seed              0.04

Egg         0.02

Fish—freshwater finfish               0.01

Fish—freshwater finfish, farm raised      0.01

Fish—saltwater finfish, other     0.01

Fish—saltwater finfish, tuna       0.01

Fruit, pome, Group 11   0.2

Goat, fat              0.05

Goat, meat         0.02

Goat, meat byproducts 0.05

Grain, aspirated fractions             65

Grain, cereal, Group 15, except sweet corn         1.0

 

 

So is it 1.0 ppm or .05 ppm?

 

Thanks!

"(other than those covered by a higher tolerance as a result of use on growing crops)" would refer to the table your crop falls under (the table you included); the limit would be 1.0 ppm. All others food stuffs/feed outside this table or not listed in any other table would be 0.05 ppm

 

 

Crop Group 15: Cereal Grains - Commodities (1.0 ppm)
Barley (Hordeum spp.)
Buckwheat (Fagopyrum esculentum)
Corn (Zea mays)
Millet, pearl (Pennisetum glaucum)
Millet, proso (Panicum milliaceum)
Oats (Avena spp.)
Popcorn (Zea mays var. everta)
Rice (Oryza sativa)
Rye (Secale cereale)
Sorghum (milo) (Sorghum spp.)
Teosinte (Euchlaena mexicana)
Triticale (Triticum-Secale hybrids)
Wheat (Triticum spp.)
Wild rice (Zizania aquatica)
