by Whole Foods Yellowfin Tuna Salad packaged in a clear plastic clamshell recall

Do not eat it. Class I means FDA judged there is a reasonable probability of serious illness or death. If the brand, size and lot or date code on your package match, throw the product away or return it to the store for a refund, and clean any surface or container it touched. If anyone has eaten it and feels unwell, contact a doctor and mention the recall. The risk from an undeclared allergen is to people allergic to soy; for anyone else the product is generally not a safety concern. FDA lists this recall as terminated: the company has finished removing the product, so it should no longer be on shelves - but it can still be in a freezer or pantry.
