How to interpret the codes on fruit stickers

Today I just found out what the meaning of the stickers that bring the fruits and the meaning of numbers that usually detail itI found it very interesting, so I want to share it with you.

This number is informing you of the method of production that has followed the fruit, which can be conventional, organic or transgenic. Well, the numbers will tell you what kind they are. Pay attention:

What are PLU codes and what are they used for?

The stickers on the fruits contain an identification code known as PLU (Price Look-Up)This system was introduced in 1990 by the International Federation for Product Standards (IFPS) and is designed to facilitate inventory control, identify the type of product and its cultivation method, and even classify products by size and variety.

These codes are volunteers, meaning not all products will include them, but they are widely used in countries such as the United States, Canada, Mexico, and others. PLU code ranges help identify three main types of production:

Products with four digits, whose first number is not 9: Fruits grown conventionally, using pesticides.
Products with five digits starting with 8: Genetically modified fruits (GMO).
Products with five digits starting with 9: Organic farming, without use of chemical pesticides or synthetic fertilizers.

How to interpret sticker codes

Identifying the production type is easy if you know how to read the code:

Conventional fruits: The codes consist of four digits and usually start with a number between 3 and 4. These fruits have been grown with the use of pesticides or chemical fertilizers. For example, the code 4011 corresponds to the conventional banana.
Organic fruits: If the code has five digits and begins with the number 9, means that the product is organic. For example, an organic banana would have the code 94011These fruits are grown without chemicals, making them a healthier and more sustainable option.
Genetically modified fruits: If the code has five digits and begins with the number 8, indicates that the product has been genetically modified. For example, a transgenic banana would have the code 84011.

Myths and facts about PLU codes

Over time, many myths have emerged regarding these codes, especially on social media. One of the most common is that the number 8 indicates that the product is genetically modified. While it is true that it is used to identify GMO products, it may also be related to the expansion of code ranges. For example, the 3000 and 4000 ranges have been exhausted, so an 8 is added at the beginning for new conventional products.

Furthermore, the absence of a PLU code in fruits does not necessarily indicate something negative. Some fruits do not include it because the system is voluntary. In addition, in some countries, additional labels such as “organic product” serve a similar purpose.

Why is it important to know these codes?

Knowing how to interpret PLU codes is a powerful tool for those who want to make more conscious choices when purchasing fruits and vegetables. It allows you to quickly identify whether a fruit has undergone chemical processing or is organic, which can align with your health and sustainability priorities.

Additionally, for those seeking to avoid genetically modified foods, PLU codes can be a useful guide. Although genetically modified products are safe, many people prefer to avoid them for personal or environmental reasons.

Other useful information about fruit stickers

These stickers not only contain the PLU code. They also often include the country of origin of the product, the name of the producer or supplier, and in some cases, a bar-code which facilitates automatic reading at cash registers.

It is important to mention that the adhesive used in these stickers is edible, although it is always advisable to remove them before eating the fruit. While they do not pose a health risk, they can alter the texture or flavor if they are not removed.

Global commitment to food labelling

The PLU system is an example of how the food industry is seeking to standardise processes to increase transparency and consumer confidence. Although it is not mandatory, its adoption has grown in many countries thanks to its logistical advantages and consumer demand for clear information.

In European countries, for example, additional labels are required to certify that a product is organic or fair trade. This complements the information already provided by the PLU code, helping consumers make more informed choices.
