Import Tolerance for 1,4SIGHT® Secured in Japan, Boosting Global Potato Trade

In a significant stride towards facilitating global potato trade, 1,4GROUP and DormFresh have announced the attainment of Import Tolerance for the sprout inhibitor 1,4-dimethylnaphthalene (1,4-DMN) in Japan.

The Japanese Ministry for Health, Labor and Welfare (MHLW) updated food residue standards in early March, incorporating a maximum residue level of 15 mg/kg for 1,4-DMN in potatoes, effective immediately. 

1,4GROUP initiated the application process for 1,4-DMN import tolerance in Japan in April 2021. Following meticulous review and risk assessment by Japanese authorities, including the Japanese Food Safety Commission, it was concluded that residues of 1,4-DMN in potatoes up to 15 mg/kg pose no health concerns.

This favorable determination underscores the safety and efficacy of 1,4-DMN, further bolstering confidence in its utilization during the storage season.

Jeanette VonKrosigk, Global Regulatory Affairs Director at 1,4GROUP:
 

"We are delighted to announce that 1,4GROUP has been granted a Maximum Residue Limit (MRL) by the Japanese Ministry of Health, Labor, and Welfare. The ministry’s assessment concluded that residues of 1,4-DMN in potatoes pose no health concerns. This favorable determination is a significant step forward in enhancing the global trade of potatoes."

The setting of import tolerance for 1,4-DMN is anticipated to promote global potato trade and optimize storage practices worldwide.
