No figures are available, and we are not aware of any serious health events. The Forestry Commission have advised that they are informally aware of some people who work close to trees being affected, and that there is likely to be some under-reporting and self-medication. Workers such as tree surgeons are at greatest risk.

Continental experience where OPM has not been controlled indicates there is the potential for lifestyle impacts. For example, in some countries, parks and woodlands have been temporarily closed to the public during outbreak events because of the potential health effects of OPM contact.
