Have you ever wondered if the little labels on your fruits and vegetables are safe to eat? Many people have accidentally swallowed them. The answer is no, produce labels are not edible. Although the materials used are regulated to be safe in the event of accidental ingestion, they are not intended for consumption. This article explains the difference between 'food-safe' and 'edible.'
Food-Safe vs. Edible: What's the Difference?
'Food-safe' means a material is approved by regulatory bodies, such as the FDA, for direct contact with food without contaminating it with harmful chemicals. Produce stickers fall into this category. The inks and adhesives meet strict guidelines to avoid contaminating the fruit. 'Edible' means a material can be safely digested and provide nutritional value. Produce stickers are not edible; they cannot be digested and offer no nutritional benefit. They will pass through the body undigested, much like chewing gum.
What are Produce Labels Made Of?
Produce stickers, also known as PLU (Price Look-Up) codes, are made of three main parts, all regulated by the FDA.
- Face-stock: This is the base material, usually a thin plastic film, like vinyl, for durability and water resistance. Some eco-friendly options use paper or biodegradable films, although this is not the standard.
- Adhesive: A food-safe, pressure-sensitive adhesive ensures the sticker sticks during packaging, shipping, and refrigeration without leaving residue. The small amount of residue left after removal is considered safe.
- Ink: The ink used for the brand name and PLU code is also food-safe and non-toxic, designed for indirect food contact.
Why You Shouldn't Eat Them
Although accidentally eating a produce sticker is harmless for most adults, it's not recommended to eat them intentionally or regularly. For young children, the sticker can be a choking hazard. Intentionally ingesting any plastic is not recommended. Research on the long-term effects of microplastics is ongoing, and it's generally advised against consumption. Always remove the sticker and wash produce thoroughly before eating.
Traditional vs. Sustainable Labels
The environmental impact of traditional labels has led to more sustainable alternatives. The material impacts durability and disposal.
| Feature | Traditional Labels | Sustainable Alternatives |
|---|---|---|
| Material | Plastic (e.g., Vinyl) | Compostable bioplastics, paper, or laser etching |
| Biodegradability | Non-biodegradable | Biodegradable and compostable |
| Water Resistance | High | Varies; can be moisture-resistant |
| Compostability | NOT compostable; contaminates facilities | Can be industrially or home compostable |
| End-of-Life Disposal | Landfill-bound trash | Compost bin |
| Cost | Generally lower | Higher |
| Availability | Widely used | Growing, but less common |
The Environmental Impact of Produce Stickers
Traditional plastic produce stickers pose an environmental challenge. They are not compostable, and they contaminate compost streams. These stickers are difficult for industrial composting facilities to filter out. This can result in microplastics in the finished compost, which then spread in the soil. For environmentally conscious consumers, removing the sticker and disposing of it in the trash is essential.
The Future of Produce Labeling
Consumer pressure and environmental regulations are pushing the industry towards sustainable solutions. Traditional labels are being replaced by eco-friendly alternatives.
- Compostable Labels: Made from plant-based materials like corn starch, these labels can be composted with fruit peels, eliminating the need to peel them off. While more expensive, they offer a clear disposal solution. Some companies already offer market-ready compostable products.
- Laser Etching: This technology uses lasers to brand produce directly on its skin, removing the need for a physical sticker. The process doesn't harm the fruit. It works best on produce with a thick skin, like avocados or mangoes, but is less viable for softer items.
What to Do with Your Produce Stickers
- Remove the sticker immediately: Peel stickers off fruits and vegetables when you get home from the store. This prevents accidental ingestion.
- Wash your produce thoroughly: Always rinse and scrub fruits and vegetables to remove any adhesive residue or surface contaminants.
- Dispose of properly: Place plastic stickers in the trash, not the compost or recycling bin.
- Opt for sustainable options: When possible, choose produce with compostable stickers or laser-etched codes.
- Support local farmers: Many farmers' market vendors do not use stickers.
Conclusion
Produce labels are not edible, even if they are made from non-toxic materials. Accidental ingestion is not a cause for alarm, but it's best to remove them before eating. This practice helps prevent environmental harm caused by plastic. As the industry evolves, sustainable alternatives like compostable labels and laser etching are becoming more common.

Frequently Asked Questions
Can you eat produce stickers?
No, produce stickers are not edible and shouldn't be eaten. Though they're non-toxic and regulated for food contact, they are not intended for digestion and have no nutritional value.
Is it harmful if I accidentally swallow a produce sticker?
For most adults, accidentally swallowing a sticker is unlikely to cause harm and will pass through your digestive system undigested. However, it is not recommended to ingest them on purpose.
What are fruit stickers made of?
Fruit stickers typically have three components: a paper or plastic face-stock, a food-safe adhesive, and non-toxic ink.
Are the adhesives on fruit stickers food-safe?
Yes, the adhesives are FDA-regulated and considered food-safe for incidental contact with food.
Are produce stickers biodegradable or compostable?
Most traditional produce stickers are not biodegradable or compostable because they're made with plastic films. They should be thrown in the trash.
Could a produce sticker be a choking hazard?
Yes, for young children, the small size and non-digestible nature of a produce sticker could pose a choking hazard. Remove them from produce before giving it to children.
What is the best way to remove fruit stickers?
Peel the sticker off. For stubborn adhesive residue, wash and lightly scrub the produce.
Why are produce stickers used?
Produce stickers use PLU codes to help identify and price fruits and vegetables correctly, differentiating between conventional and organic items.
Are there edible produce labels?
Some companies are developing edible labels, but they are not widely available.
How can I avoid produce stickers?
Shop at farmers' markets, which often don't use stickers, or look for produce with sustainable alternatives like laser etching or compostable bands.
