Vegan burgers and plant milks have quietly become pantry staples for anyone trying to eat a little cleaner. But a new food safety study is asking a question most shoppers never think to ask: what else is hiding in that patty besides pea protein?
- Every one of 212 plant-based meat and milk products tested in a UK study contained at least one of 19 different fungal toxins called mycotoxins.
- The toxin levels found were below EU safety limits, so no product needed to be pulled off shelves.
- Mycotoxins form naturally on grains, legumes, and seeds during growing or storage, so they are hard to avoid completely in any plant-based food.
- Researchers warn that small amounts eaten repeatedly over years can add up, and heavy long-term exposure has been linked to liver and kidney strain.
- Choosing whole, minimally processed plant foods over heavily engineered meat substitutes is one simple way to lower your overall exposure.
Yes, a 2026 study from the University of Parma and Cranfield University found mycotoxins, natural toxins produced by mold, in every single one of 212 plant-based meat alternatives and plant milks tested in the UK market. The products included vegan burgers, chicken-style pieces, sausages, and oat, almond, and soy milks, and the team detected at least one of 19 different mycotoxins in each item, with many carrying more than one. Concentrations stayed under European Union safety limits, so this is not a recall-level emergency. But the finding, published in the journal Food Control, is a good reminder that "plant-based" and "processed" are not the same thing as "risk-free," and that small, repeated exposures over months and years matter more than any single meal.
Why Mold Shows Up in Foods That Never Touch Meat
It sounds strange that a veggie burger could carry the same family of toxins people worry about in stored grain. But the raw materials tell the story. Plant-based meat and milk alternatives are built from cereals, legumes, nuts, and seeds, and these crops can pick up mold while still growing in the field, during harvest, or while sitting in storage or transit. Andrea Patriarca of Cranfield University, one of the researchers on the study, put it simply: mycotoxins occur naturally in foods and cannot be completely avoided. The more a product depends on these raw ingredients, the more chances there are for contamination to slip through before the final package ever reaches a shelf.
What the Researchers Actually Found
The team screened 212 products sold in the UK, spanning burgers, sausages, chicken-style pieces, and oat, almond, and soy-based milks. Across the entire sample, every product contained at least one of 19 mycotoxins, and several contained more than one type at once. The reassuring part is that none of the levels exceeded existing EU guideline limits for food safety. The less reassuring part is that mycotoxin monitoring for many of these newer plant-based products is not yet standardised the way it is for staple grains, which is why the researchers are calling for clearer regulatory oversight as this category keeps growing.
Should You Stop Buying Plant-Based Meat?
Not necessarily, and the researchers themselves are careful not to frame this as a reason to panic. An occasional veggie burger at a barbecue is not the concern. The concern is repetition: eating the same category of heavily formulated, ultra-processed food day after day, where any low-level contamination compounds with every serving. In more severe, sustained exposure cases, mycotoxins such as aflatoxin have been linked to liver and kidney damage and immune suppression, so the real lesson here is about variety and frequency, not one single food being "bad."
The Case for Fewer Ingredients, Fewer Unknowns
This is really a story about how far an ingredient travels before it reaches your plate. A product engineered to mimic meat usually passes through many more processing steps than a snack made from a handful of whole ingredients, and each step is another point where quality can slip. Traditional Indian foods built on millets, dry fruits, nuts, and jaggery were never trying to imitate anything else, which keeps the ingredient list short and the process simple. If you are looking to swap a heavily processed snack for something with fewer unknowns, our Baked Ragi Chips, made from whole ragi (finger millet) and baked rather than fried, are a small, practical step in that direction. For a broader look at whole-ingredient snacking, our full range sticks to the same principle.

Frequently Asked Questions
1. What are mycotoxins?
Mycotoxins are toxic compounds produced naturally by certain molds that grow on crops like grains, legumes, nuts, and seeds, either in the field or during storage. They are not added by manufacturers. Most foods contain trace amounts, and regulators set safety limits to keep exposure low, but they cannot be removed entirely from the food supply.
2. Are plant-based meat alternatives safe to eat?
Yes, for most people eating them occasionally. A 2026 study found mycotoxins in all 212 products tested, but every sample stayed below EU safety limits. The concern researchers raised is about repeated, long-term consumption of the same processed products, not the safety of eating one now and then.
3. Which foods are most likely to contain mycotoxins?
Cereals, legumes, nuts, seeds, and dried fruits are the most common carriers, since mold can develop on these crops during growing, harvesting, or storage. Products made heavily from these raw ingredients, including plant-based meat substitutes and some plant milks, tend to show detectable but generally low levels.
4. Can cooking or baking destroy mycotoxins?
Not reliably. Most mycotoxins are heat-stable, meaning normal cooking, baking, or frying temperatures do not break them down completely. Prevention during growing and storage, along with good quality control and testing, is far more effective than trying to cook the toxins away afterward.
5. How can I reduce my exposure to mycotoxins in food?
Eat a varied diet instead of relying heavily on one processed product, buy from brands that test raw ingredients, and store grains, nuts, and dried fruits in cool, dry, airtight conditions at home. Discard any nuts or grains that look moldy, discolored, or smell musty rather than trying to salvage them.
