Sec. 170.19  Pesticide chemicals in processed foods.

    When pesticide chemical residues occur in processed foods due to the 
use of raw agricultural commodities that bore or contained a pesticide 
chemical in conformity with an exemption granted or a tolerance 
prescribed under section 408 of the Act, the processed food will not be 
regarded as adulterated so long as good manufacturing practice has been 
followed in removing

any residue from the raw agricultural commodity in the processing (such 
as by peeling or washing) and so long as the concentration of the 
residue in the processed food when ready to eat is not greater than the 
tolerance prescribed for the raw agricultural commodity. But when the 
concentration of residue in the processed food when ready to eat is 
higher than the tolerance prescribed for the raw agricultural commodity, 
the processed food is adulterated unless the higher concentration is 
permitted by a tolerance obtained under section 409 of the Act. For 
example, if fruit bearing a residue of 7 parts per million of DDT 
permitted on the raw agricultural commodity is dried and a residue in 
excess of 7 parts per million of DDT results on the dried fruit, the 
dehydrated fruit is adulterated unless the higher tolerance for DDT is 
authorized by the regulations in this part. Food that is itself ready to 
eat, and which contains a higher residue than allowed for the raw 
agricultural commodity, may not be legalized by blending or mixing with 
other foods to reduce the residue in the mixed food below the tolerance 
prescribed for the raw agricultural commodity.
