Designation of Substances Used  as Ingredients of Agricultural Chemicals  
That Are Stipulated to be “Should Not be Detected ” in Food  
 
 
In Japan, the Food Sanitation Act authorizes the Minister of Health, Labour 
and Welfare (MHLW)  to establish residue standards (maximum residue 
limits: MRLs) for pesticides, feed additives, and veterinary drugs (hereafter 
referred to as “agricultural chemicals”) that may  remain in foods. Any food 
for which standards are established pursuant to the provisions in the act is 
not permitted to be marketed in Japan unless it complies with the established 
standards.  
 
The Food Safety Commission of Japan (FSC) has recently conduct ed risk 
assessment for  Nitarson e and concluded that an Acceptable Daily Intake 
(ADI) should not be established because t he substance is likely to  be genotoxic  
and carcinogenetic . 
 
Based on the conclusion of the FSC, the MHLW has decided to designate  it as 
an ingredient of the agricultural chemicals that are  stipulated to be " Should 
not be detected" in food .
