Japan's "positive list system" main content

The main content of Japan's "positive list system" is "Provisional Maximum Residue Limits" and Uniform Limits. The tentative standard is to set a new residue limit standard for current general-purpose pesticides, veterinary drugs and feed additives; the standard is to set 0.01ppm for pesticides, veterinary drugs and feed additives that cannot yet be determined as “provisional”. Unified standards. Specific content includes:

1. Set residue limits for all agricultural chemicals used in the world;

2. Prepare tentative standards for agricultural chemicals that already have residual limit values ​​or reference materials with a provisional residue limit value, and review the changes every 5 years based on changes in reference data and new toxicology data;

3. For agrochemicals that lack reference materials for setting a residual limit value, a uniform standard of 0.01 ppm is established;

4. The use of "Not Detected" as the standard for agricultural chemicals that may be carcinogenic and cannot set daily allowances;

5. For pesticides that are not used in Japan or are used only in limited crops, other countries can apply for their use on specific crops and establish maximum residue limits through the foreign application system established by the Ministry of Health, Labour and Welfare;

6. It is forbidden to sell foods containing agricultural chemicals that are not listed in the "affirmative list" and whose agricultural chemical content exceeds tentative standards or uniform standards;

7. If the raw material meets the limit standard, it is considered that the processed product also meets the corresponding standard;

8. Following the entry into force of the "positive list system" (not later than May 2006), the temporary residue limit will be implemented as a statutory standard and a six-month transitional period will be granted;

9. The list of exempt substances (ie, agricultural chemicals that obviously do not cause damage to human health) has been identified.
