Pyrrolizidine alkaloids (PAs) in honey and pollen-legal regulation of PA levels in food and animal feed required. Acute liver toxicity, specifically in the form of hepatic veno-occlusive disease (HVOD), is known from reports on human poisonings following ingestions of 1,2-unsaturated pyrrolizidine alkaloids (PAs) containing herbs. Just recently pyrrolizidine alkaloids were also found in both herbal teas and common teas. 2002 May 8;50(10):2719-30. doi: 10.1021/jf0114482. 28, No. 2019 Dec 11;11(12):726. doi: 10.3390/toxins11120726. To date, approximately 600 different PAs are known. Due to their carcinogenic potential, 1-2 unsaturated pyrrolizidine alkaloids in particular should not be contained in food and feed.

Pyrrolizidine alkaloids are probably the major alkaloidal food contaminants in terms of wide distribution and the degree of economic and health damage caused. there is no safe level, and therefore a “tolerable intake level” cannot be established and exposure should be reduced to as low as reasonably practicable (ALARP).1 Food Addit Contam Part A Chem Anal Control Expo Risk Assess.

Pyrrolizidine alkaloids are a large group of natural toxins produced by plants that have been associated with livestock diseases and human poisoning after contamination of staple foods. PAs are toxins exclusively biosynthesised by plants. Apart from the toxicity that these molecules can cause in humans and livestock, PA are also known for their wide range of pharmacological properties, which can be exploited in drug discovery programs. pyrrolizidine alkaloids (PAs) in selected food items, to estimate the dietary exposure to PAs of the Hong Kong adult population and to assess the associated health risks. The European Food Safety Authority (EFSA) was asked by the European Commission to deliver a scientific opinion on pyrrolizidine alkaloids (PA) in food and feed. Growing recognition of hazardous levels of dehydroPAs in a range of common foods suggests that physicians and clinicians need to be alert to the possibility that these contaminants may, in some cases, be a possible cause of chronic diseases such as cirrhosis, pulmonary hypertension and cancer in humans.
