Organic food is often seen as cleaner, safer, and less contaminated by toxic chemicals than mass produced food. This view focuses on pesticide use, synthetic additives, and farming practices and not on other factors, like environmental pollutants. Unfortunately, microplastics are an environmental pollutant that can make their way into plants. Sadly, organic foods aren’t immune to microplastics. The latest research shows that microplastics are in both organic and non-organic foods.

Organic certification doesn’t mean it’s microplastic-free

Organic standards regulate things like pesticides, fertilizers, and the makeup of the animals’ food, but these standards don’t regulate certain types of environmental contamination. Microplastics, which have been found in agricultural soils, irrigation water, atmospheric dust, and processing environments, make their way into organic crops and food for animals. Because they’re virtually everywhere and microscopic in nature, they’re almost impossible to remove from these foods.

Once microplastics are present in the surrounding environment, organic production systems have no structural mechanism to filter them. Airborne fibers can settle on crops, particles in water can contact plant roots, and livestock can ingest microplastics through feed, water, and the ground itself. Organic labeling therefore exclusively reflects farming philosophy and use of certain chemicals, and doesn’t protect these foods from microplastic particulate pollution. Even if a food is labeled as organic, there can still be microplastics in organic foods.

Microplastics have been detected in organic milks

Analytical studies have found microplastics in milk across conventional, raw, and organic categories, demonstrating that organic dairy production does not eliminate contamination risk [1]. The scientists speculated that the particles come from multiple sources, including animal contact with contaminated water, airborne fibers in barns, and plastic materials used during milking and processing. These sources contribute to microplastics in organic foods.

The findings suggest that the milk can be contaminated with microplastics at virtually all stages of production. The cow can eat, drink, or breathe in microplastics and pass it to the milk. Textiles used for udder cleaning, worker clothing, and plastic packaging all contribute potential microplastic inputs [1]. The movement of the milk from the pail to another container can also contribute. As a result, organic milk reflects the same environmental burden observed in non organic dairy products.

Organic protein sources are also contaminated with microplastics

Research examining commonly consumed protein sources found no statistically significant difference in microplastic contamination between products purchased from conventional supermarkets and those labeled as natural or organic [2]. This suggests that organic sourcing doesn’t reliably reduce microplastic exposure. Instead, contamination appears to be influenced more strongly by processing, handling, and ambient environmental conditions. However, more research is needed to confirm this.

In these studies, because the brand or store didn’t matter, it suggests that microplastics enter the food chain at many different stages [2]. For example, microplastics from the air and processing environments are shared contamination points across the entire food supply chain, regardless of if the food is organic or not.

Organic farming practices can even introduce microplastics to food

While organic agriculture avoids synthetic fertilizers, it frequently uses composts and organic inputs that can contain microplastics. Research has shown that organic fertilizers contain microplastics and add them to agricultural soils [3]. These microplastics persist over time and accumulate each time compost or the organic matter is added.

The long term use of organic compost has been linked to increases in soil microplastic concentrations in crop rotation systems [4]. Once present in soil, microplastics can interact with plant roots and sometimes be taken up into edible plant tissues [5]. This shows that organic practices don’t necessarily reduce microplastic exposure.

Microplastics move through biological systems

More alarmingly, microplastics can act as carriers for other environmental pollutants, including polycyclic aromatic hydrocarbons and heavy metals, amplifying their potential, negative biological impact [1]. Studies have documented microplastics in human blood, placenta, and breast milk, demonstrating their ability to move through the body after consumption.

These findings actually highlight a key limitation of organic food labeling. Certification addresses farming intent, but not environmental ubiquity. Unfortunately, significant changes will need to be made to many areas of food creation, processing, and distribution in order to entirely remove microplastics, assuming that it’s even possible.

Although there are microplastics in organic foods, organic is still the smartest choice

Organic food provides a wealth of meaningful benefits related to pesticide exposure, biodiversity, and soil health. However, current evidence shows that organic foods aren’t free from microplastics or consistently lower in microplastic contamination. Microplastics represent a class of pollutant governed by global plastic production, environmental ubiquity, and current food growing and distribution practices.

The presence of microplastics in organic foods raises significant concerns regarding food safety and the integrity of organic farming practices. Despite the rigorous standards that govern organic production, the inadvertent introduction of microplastics poses a challenge that cannot be overlooked. Continued research is essential to identify and mitigate the sources of contamination, ensuring the protection of consumer health and the credibility of organic food labeling. Addressing this issue is imperative for maintaining consumer trust in organic food products.

Understanding this key distinction allows you to make informed decisions without relying on false assurances or sneaky marketing. Reducing microplastic exposure requires attention to processing, packaging, water quality, and broader lifestyle factors that extend beyond just the organic label. That’s why we created the Deplasto platform.

The Deplasto platform, consisting of a scientifically-backed nutritional supplement, an iOS app for tracking daily microplastic intake, and a portfolio of lifestyle recommendations intended to help you minimize microplastics.

Our nutritional supplement is formulated to support your body’s natural detoxification pathways, including oxidative stress management, cellular repair, and antioxidant support. Our microplastic intake app enables you to estimate and track your daily microplastic intake, with each datapoint backed by scientific studies. Our lifestyle recommendations, found in our blogs and in our eBook, have a plethora of actions and advice designed to help you make small changes to minimize microplastics.

Overall, we believe that the best way to eliminate microplastics begins with you and the small changes you make to your daily life. Over time, collectively, we can make a significant difference.
