Seasonal Produce – Raisins

Are raisins an insect concern?
Recent studies by the OK Tolaim Lab concluded that, under normal conditions, raisins are not Halachically problematic and do not require checking — provided they are stored properly.

Key factors:
Infestation rates: For a food to require checking, at least 10% of similar produce (miut ha’matzui) must be infested. It has not been conclusively established that raisins meet this threshold.
Halachic leniency: The Taz (YD 84:12) writes that raisins involve a built-in double doubt (safek sfeika): maybe there are no insects, and even if there are, they may have developed after harvest (lo pirshu), which is permitted.

Recommendation: When OK Kosher certifies raisins, we carefully inspect facilities to ensure proper conditions that prevent infestation and minimize risk. It is always preferable to buy raisins with a reliable hechsher, since uncertified products may not uphold these standards. As a precaution, give raisins a quick visual check before eating. If insects are seen, those raisins should not be consumed.
