Mycotoxins have shown up in almost all plant-based proteins and beverages tested in the United Kingdom and Italy, but it’s unlikely to be a health threat to most people.
The researchers studied 212 plant-based products such as burgers, vegan sausages, chicken mimics and milks made of oats, almonds or soybeans.
All of them contained at least one of 19 mycotoxins, with multiple products containing more than one.
The study says that previous research has demonstrated that even at low levels, if consumed often, mycotoxin can build up exposure and lead to potential health concerns, but occasional consumption should not pose a danger.
In extreme cases mycotoxin exposure can lead to liver and kidney damage, immune system suppression, and cancer, the report said.
The researchers advise that monitoring of raw materials be extended.
“Mycotoxins occur naturally in foods and cannot be completely avoided. As consumers, we should not be frightened or deterred from enjoying a variety of products,” said Andrea Patriarca, senior lecturer in mycology at Cranfield University.
“However, a significant concern arises when new foods enter the market, as there are currently no established regulations to monitor mycotoxins.” she said.
The study found that mycotoxin levels United Kingdom plant-based foods that were tested were lower than recommended European Union guideline levels, which it said reflected the high-quality standards of the UK food industry.
The study was a joint effort by the University of Parma in Italy and Cranfield University in the United Kingdom.
