Pyrrolizidine alkaloidosis is known by many other names such as "Pictou Disease" in Canada and "Winton Disease" in New Zealand. Pyrrolizidine alkaloids are natural toxins produced by a wide range of plant species. J Agric Food Chem. Cases of acute poisoning with pyrrolizidine alkaloids in foods are expected to only occur ex- pected rarely in Germany and Europe. A first discussion paper on Pyrrolizidine Alkaloids (PAs) in Food and Feed and Consequences for Human Health (CX/CF 11/5/14)1 was prepared by an electronic working group, led by the Netherlands, for discussion at the 5th CCCF.

Various research projects and studies conducted by the official authorities of the federal states detected pyrrolizidine alkaloids in various samples of food and feed, in some cases in high concentrations. eCollection 2020 Mar. This site needs JavaScript to work properly. To date, over 10,000 PAs poisoning cases have been reported worldwide. doi: 10.1016/j.heliyon.2020.e03593. Exposure to PAs needs to be minimised because of the health risks associated with them. grain, milk, meat, eggs, honey, pollen). Ingestion of 1,2 unsaturated PAs can be damaging to the liver; they are genotoxic and may act as carcinogens in humans. 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. 2011 Mar;28(3):293-307. doi: 10.1080/19440049.2010.547519.

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. 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.

Herbal medicines and teas containing dehydroPAs have also caused fatalities in both developed and developing countries. PAs are toxins exclusively biosynthesised by plants. To date (2011), there is no international regulation of PAs in food, unlike those for herbs and medicines. Some plants consumed by humans contain pyrrolizidine alkaloids naturally but other foods can become contaminated with pyrrolizidine alkaloids when weeds producing these toxins are accidentally harvested along with the crop. and Crotalaria retusa. The 3% of the flowering plants produce these type of molecules and grow as weeds in agricultural production systems throughout the world where they can contaminate commonly consumed foods (eg. Pyrrolizidine alkaloids are probably the major alkaloidal food contaminants in terms of wide distribution and the degree of economic and health damage caused. 0000001381 00000 n Mol Nutr Food Res. Due to their carcinogenic potential, 1-2 unsaturated pyrrolizidine alkaloids in particular should not be contained in food and feed.

Pyrrolizidine alkaloidosis is known by many other names such as "Pictou Disease" in Canada and "Winton Disease" in New Zealand. Pyrrolizidine alkaloids are natural toxins produced by a wide range of plant species. J Agric Food Chem. Cases of acute poisoning with pyrrolizidine alkaloids in foods are expected to only occur ex- pected rarely in Germany and Europe.

In a recent European Food Safety Authority (EFSA) opinion, only two data sets from one European country were … Health risks from a chronic exposure are the main pri- ority for the risk assessment. Adv Food Nutr Res. Contamination of grain with 1,2-dehydropyrrolizidine ester alkaloids (dehydroPAs) and their N-oxides is responsible for large incidents of acute and subacute food poisoning, with high morbidity and mortality, in Africa and in central and south Asia. 0000006959 00000 n 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 Molyneux RJ, Gardner DL, Colegate SM, Edgar JA. 0000008505 00000 n The COT was asked for its view on the risk assessment of pyrrolizidine alkaloids in food and whether it considered potential human Pyrrolizidine Alkaloids. Occurrence and Risk Assessment of Pyrrolizidine Alkaloids in Spices and Culinary Herbs from Various Geographical Origins. Sampling protocols 217 5. Introduction. Biological data 21 3. PAs have been reported to be hepatotoxic, mutagenic, and carcinogenic; they are a significant group of natural toxins affecting livestock, wildlife, and humans. This suggests that there may have been cases of disease in the past not recognised as resulting from dietary exposure to dehydroPAs. USA.gov. The pyrrolizidine alkaloid content of seeds is often very high (up to 5% dry weight) and the effects can be acute or cumulative. Background 1. 2020 Mar 31;6(3):e03593. 2003;45:61-99. PAs are a group of secondary compounds that are produced by plants all over the world. (comfrey) are deliberately ingested while the remaining species are weeds in various grain crops. NLM They are found worldwide in a very large number of plants. 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. 0000000831 00000 n Explanation 4 2. 104 0 obj << /Linearized 1 /O 106 /H [ 971 410 ] /L 63159 /E 8941 /N 16 /T 60960 >> endobj xref 104 24 0000000016 00000 n There is now increasing recognition that some staple and widely consumed foods are sometimes contaminated by dehydroPAs and their N-oxides at levels that, while insufficient to cause acute poisoning, greatly exceed maximum tolerable daily intakes and/or maximum levels determined by a number of independent risk assessment authorities. 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. Honey from plants containing pyrrolizidine alkaloids: a potential threat to health. 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.
