Is sake or other rice-based alcohol a hidden source of pesticides for daily drinkers?
Sometimes. Some commercial sakes carry detectable neonicotinoids from the rice they're made with.
What's actually in it
Sake is made by fermenting polished rice. The polishing step removes some of the bran where pesticides like neonicotinoids tend to concentrate, but not all. Whatever residue is left dissolves into the alcohol during brewing and into the bottle.
This applies to other rice-based alcohols too, including shōchū and some flavored liqueurs.
What the research says
A 2026 study in Food Addit Contam Part A tested Japanese sakes for systemic insecticides. Detectable neonicotinoid residues showed up in many samples. The amounts were small per glass, but added up for daily drinkers. The team called it the first report of its kind for sake.
The risk score wasn't huge. It was still big enough to flag for steady drinkers and pregnant women.
For lighter exposure, pick organic sake or shōchū where you can find it. Limit daily intake. Junmai daiginjo sakes use more highly polished rice, which usually carries less residue. Pregnant women and people trying to conceive should skip alcohol overall, which solves the problem.
