How long can sushi rice be left out?

Properly acidified sushi rice can be left at room temperature for up to 4 hours, thanks to the vinegar inhibiting bacteria, but must be discarded after that limit. Unacidified or improperly handled rice should only sit out for 2 hours, or less in warm conditions, to prevent rapid bacterial growth, as cooked rice can harbor heat-resistant spores. For best quality and safety, refrigerate any leftovers in an airtight container and consume within 1-2 days, though it's best used soon after preparation.
