How long must a food establishment keep the shellstock identification tags that come with live shellfish?

Giải thích

Shellstock identification tags must be kept, in order and marked with the date the last shellfish was used, for 90 days from that date, so illnesses can be traced back to the harvest source. Discarding the tag 24 hours after the container is emptied is far too short for traceback; the 7-day figure is the date-marking limit for ready-to-eat food, not the tag-retention rule; and a full year is more than the Code requires. The tag links each container to its harvest location and date.
