Virtually all the data on the subject link most human health problems associated with bracken fern to exposure to contaminated milk from animals eating bracken, contaminated groundwater near bracken stands, and, in some cases, long-term exposure to bracken spores; so if your yard is covered in bracken fern, you might want to dig most of it up. There is no tumour (or other disease) that is pathognomic of exposure in animals, though, Glyphosate is a non-selective herbicide (otherwise known as a total herbicide) that will. 2015 Jan;8(1):1-8. doi: 10.1158/1940-6207.CAPR-14-0160. Milk from cows that graze bracken fern may be hazardous to humans. Once valued and gathered for use in animal bedding, tanning, soap and glass making and as a fertiliser, bracken is now seen as a pernicious, invasive and opportunistic plant, taking over from the plants traditionally associated with open moorland and reducing easy access by humans. 2016 Mar;88:91-9. doi: 10.1016/j.mehy.2015.11.007. Toxic Principle. doi: 10.1371/journal.pone.0218628. Med Hypotheses. Issues over bracken toxicity and its use as a soil improver are also of importance to gardeners. 2019 Jun 21;14(6):e0218628. Worldwide relationships in the fern genus Pteridium (bracken) based on nuclear genome markers. eCollection 2019. Toxic phytochemicals and their potential risks for human cancer. Some human populations also eat young bracken shoots and epidemiological studies in Japan and Brazil have shown a close association between bracken consumption and cancers of the upper alimentary tract. When we think of toxins in plants, we don’t ordinarily think of the lowly fern. The type and severity of any poisoning event will vary greatly from place to place because the amount of each poison produced by a particular population of bracken plants is highly variable. ), from eastern Australia and from a cultivated worldwide collection held in Sydney, Australia. Grazing animals may consume Bracken when normal foods are unavailable (such as during adverse weather). Its spores contain the enzyme thiaminase, which is considered to be bone damaging and carcinogenic. Concentration of ptaquiloside, a major carcinogen in bracken fern (Pteridium spp. Human gastric cancer, Helicobacter pylori and bracken carcinogens: A connecting hypothesis. It is said to be the 5th most common plant, an important toxic plant and the only higher plant known to cause cancer in animals. Bracken … Am J Bot. Epidemiologic studies suggest that consumption of milk from cattle with access to bracken produces increased risk of human esophageal or gastric cancer. Bracken is perhaps the most broadly distributed of all fern species and among the most wide-ranging of all vascular plants. The ostrich fern is the safest fern to eat, even though it, too, can contain toxins. This work reviews the bracken-cancer connections established by in vitro and in vivo experiments and epidemiological studies in various parts of the world, and provides insights into the possible bridges for bracken carcinogens to reach the human diet. The mature bracken fern can be mildly poisonous. The plant is carcinogenic to animals such as mice, rats, horses and cattle when ingested, although they will usually avoid it unless nothing else is available.
