stickers

Stickers, in a culinary context, are decorative or informational adhesive labels applied to produce and packaged food items. In modern food commerce, produce stickers are typically small, round labels affixed directly to fruits and vegetables during or after harvest, bearing a Price Look-Up (PLU) code—a standardized four or five-digit number that identifies the product type, variety, and growing method (conventional or organic) to facilitate point-of-sale scanning and inventory management. These stickers are composed of food-safe materials including a printed layer, adhesive backing, and carrier film, designed to adhere without damaging the skin of delicate produce or compromising food safety.

Stickers on produce serve a commercial and regulatory function rather than a direct culinary purpose. In the kitchen, the primary task is removal: stickers should be peeled away before washing and consuming fresh produce to prevent ingestion of adhesive materials and to allow proper cleaning of the fruit or vegetable surface. Some cooks soak produce briefly in warm water to loosen stubborn stickers. While the stickers themselves are not consumed, understanding PLU codes can inform ingredient selection and sourcing decisions, particularly when distinguishing between organic and conventionally grown produce.
