Pyrrolizidine alkaloids in food: downstream contamination in the food chain caused by honey and pollen. Pyrrolizidine alkaloids (PA) are widely distributed in plants throughout the world, frequently in species relevant for human consumption. (comfrey) are deliberately ingested while the remaining species are weeds in various grain crops. 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. A review of the literature shows that there are a number of reports of liver disease where either exposure to dehydroPAs was suspected but no source was identified or a dehydroPA-aetiology was not considered but the symptoms and pathology suggests their involvement.

Pyrrolizidine alkaloids (PAs) are widely distributed plant toxins with species dependent hepatotoxic, carcinogenic, genotoxic and pneumotoxic risks. PAs have been reported to be hepatotoxic, mutagenic, and carcinogenic; they are a significant group of natural toxins affecting livestock, wildlife, and humans. 0000001576 00000 n 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 … Pyrrolizidine alkaloids (PA) are an extensive group of secondary plant ingredients, which can be found, for example, in herbal teas and dried seasoning herbs, plant extracts that can enter the respective product through non-sorted herbs. 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 alkaloidosis is known by many other names such as "Pictou Disease" in Canada and "Winton Disease" in New Zealand. These compounds … Chem Res Toxicol. Mol Nutr Food Res.

PAs are a group of secondary compounds that are produced by plants all over the world. (3) In April 2013, the Authority published a call for proposals to investigate the concentrations of pyrrolizidine alkaloids in animal-derived food products including milk and milk products, eggs and meat and meat products, and for plant-derived food products including (herbal) teas and food supplements, across different regions in Europe.

The COT was asked for its view on the risk assessment of pyrrolizidine alkaloids in food and whether it considered potential human 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 Author information: (1)Department of Veterinary Sciences, Utah State University, Logan, UT 84322-4620, USA. Background 1. Levels and patterns of contamination of food commodities 225 7. Epub 2014 Dec 26. Toxins (Basel). 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. More than 660 PAs have been identified in over 6000 plant species. Cereal crops and forage crops can sometimes become polluted with pyrrolizidine-containing seeds, resulting in the alkaloids contaminating flour and other foods, including milk from cows feeding on these plants. Kisielius V, Hama JR, Skrbic N, Hansen HCB, Strobel BW, Rasmussen LH. 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. Pyrrolizidine alkaloids are a reason for concern because of their bioactivation to reactive alkylating intermediates. Herbal medicines and teas containing dehydroPAs have also caused fatalities in both developed and developing countries.  |  Get the latest public health information from CDC: https://www.coronavirus.gov, Get the latest research information from NIH: https://www.nih.gov/coronavirus, Find NCBI SARS-CoV-2 literature, sequence, and clinical content: https://www.ncbi.nlm.nih.gov/sars-cov-2/. Pyrrolizidine alkaloids (PAs) are secondary metabolites of plants. This suggests that there may have been cases of disease in the past not recognised as resulting from dietary exposure to dehydroPAs. Pyrrolizidine alkaloids are natural toxins produced by a wide range of plant species. The decomposition of toxic pyrrolizidine alkaloids in ragwort (Senecio jacobaea) on storage in waste bags has been evaluated by a new time-of-flight mass spectrometric detection method.

Pyrrolizidine alkaloids are probably the major alkaloidal food contaminants in terms of wide distribution and the degree of economic and health damage caused. Pyrrolizidine alkaloids (PAs) are synthesised by plants as their secondary metabolites and are considered to be one of the most widespread toxins of natural origin (1, 23).PAs have gained attention in the recent years due to their hepatotoxic, carcinogenic, genotoxic, and pneumotoxic properties ().More than 6,000 plant species produce alkaloids and more than 660 PAs … 2015 Jan 20;28(1):4-20. doi: 10.1021/tx500403t.
