Sphagnum Moss For Bonsai The Benefits and Dangers of using Sphagnum Moss for Bonsai
The Dangers of Sphagnum
In recent months there have been a number of warnings issued on the Internet and other publications concerning the dangers of using and handling sphagnum moss. Many of these sources quote a statement made by the Canadian Sphagnum Peat Moss Association
".Sphagnum moss can be a source of a chronic fungal disease called sporotrichosis, which enters the skin through scratches and abrasions. From there it can get into your lymph nodes and cause swelling of the joints. The entry point will develop blisters. If treatment is not given, amputation of the infected area can become necessary; death from the disease can also occur."
Since sphagnum moss has many very useful properties that can be used for bonsai cultivation and is widely used by enthusiasts, how seriously should the above warning be taken?
Sporotrichosis is a fungal infection that usually affects the skin. It is mainly an occupational disease of farmers, gardeners, and horticulturists.
Though the fungus that carries sporotrichosis is found in sphagnum moss, it should be noted that it also occurs and can be transmitted into cuts in human skin via soil, hay, barbed wire, pine needles, thorns (particularly those of the Rose family such as Rose species and Hawthorn) and other plant materials. It has also been found growing on plant debris in soil and on the bark of trees and shrubs, (wild and cultivated). The threat of Sporotrichosis is certainly not limited to just Sphagnum Moss.
It should also be understood that not all Sphagnum moss carries Sporotrichosis. According to reports by the Wisconsin Division of Health, Bureau of Community Health and Prevention (BCHP), in 1981 a diagnosis of sporotrichosis was found in two brothers employed at a garden centre in Wisconsin. An investigation of the garden centre by the BCHP revealed two additional cases of sporotrichosis among the employees.
The garden centre had sixteen workers make funeral wreaths during the Winter of 1980. The sphagnum moss used was harvested from bogs located in central Wisconsin and was purchased from one wholesale dealer.
Of seven male workers regularly involved in making the wreaths, four developed sporotrichosis.
However, in an investigation of a local cemetery where 12 employees produced 2,000-3,000 wreaths per autumn using sphagnum moss purchased from the same Wisconsin supplier, no additional cases were noted.
It appeared that the source of the outbreak was limited to just one bad batch of Sphagnum from a wholesale dealer who had also supplied countless quantities of Sphagnum free of Sporotrichosis.
It would appear that in the majority of cases such as this one, Sphagnum carry the fungus causing Sporotrichosis is the exception rather than the rule.
Most Sporotrichosis infections are limited to the skin. Cases of joint, lung, and central nervous system infection have occurred but are very rare.
The first symptom of Sporotrichosis is usually a small painless bump that looks like an insect bite. It can be red, pink, or purple. The bump usually appears on the finger, hand, or arm where the fungus first entered through a break in the skin. This is followed by one or more additional bumps that open, might look like boils, and are very slow to heal. The first skin bump can appear any time from 1 to 12 weeks after exposure to the fungus, but usually within 3 weeks.
Until recently, sporotrichosis was treated with potassium iodide, however a new drug Sporanox is now used for treatment because it causes fewer side effects than potassium iodide. Treatment can often take several weeks until the skin sores are completely healed.
Bear in mind that the risk of Sporotrichosis is very small; in the US the incidence of infection is not precisely known but is estimated at only 1-2 cases per million people. An estimated 200-250 cases occur per year. Statistically speaking, it is more dangerous to cross the road.
I handle soil, trees, sphagnum moss on a daily basis and have done for a number of years without incident as have many other enthusiasts, nurserymen and gardeners, however I am duty bound to advise that where possible, wear gloves and long sleeves when handling wires, rose bushes, hay bales, pine seedlings, or other materials that can prick the skin on a continual or daily basis. If you have broken areas of skin, avoid prolonged direct contact with soils, sphagnum moss and similar materials.
