EFSA updates advice on the risks from pyrrolizidine alkaloids / by Joris Geelen

Pyrrolizidine alkaloids (PAs) are a large group of toxins produced by different plant species. EFSA was asked by the European Commission to deliver a scientific opinion on the risks for human health related to the presence of PAs in honey, tea, herbal infusions and food supplements.

A new exposure assessment including new occurrence data was used to update the risk characterisation. EFSA established a new Reference Point of 237 μg/kg body weight per day to assess the carcinogenic risks of PAs. It was furthermore concluded that, although no occurrence data were available, exposure to PAs from pollen, tea, herbal infusions could potentially present a risk of both acute and chronic effects in the consumer. It was also noted that consumption of food supplements based on PA-producing plants could potentially result in exposure levels causing acute/short-term toxicity. 

In Belgium a maximum level for toxic pyrrolizidine alkaloids of 4 µg/kg applies for the use of 4 botanicals of the Boraginaceae family in food supplements.
