Pigeon Guano Removals
Pigeon Guano Removal
RS Asbestos Ltd have a very effective and reliable bird dropping removal service. Our team of highly trained technical experts are able to clean up pigeon guano in a number of varied locations including high, hard to reach areas. All of our technicians are fully trained in the dangers of carrying out this highly hazardous cleaning procedure.
In our experience, pigeon mess can and has been located in some of the most difficult areas to reach such as loft spaces and high ledges. We are able to provide you with a quick and efficient service to remove the bird droppings in the safest manner and dispose of correctly according to Waste Regulations. We have carried out pigeon cleaning in hospitals, loft spaces, factories, warehouses, breweries, barns, churches, balconies, air conditioning units, boiler houses and many more.
An estimated 2,000 people a year in Britain are catching infections from wild pigeons, which carry up to 60 diseases. In five years the number of pigeons in British towns and cities is estimated to have doubled. In Trafalgar Square alone there are 30,000 to 40,000.
Disease organisms commonly found in bird and bat excrement
a. The high nutrient content of accumulated bird and bat excrement provides an excellent growth medium for organisms of potential human health concern. This guide primarily addresses the prevention of two illnesses caused by those organisms: cryptococcosis and histoplasmosis.
b. Cryptococcosis is usually associated with pigeon droppings at elevated roost sites; histoplasmosis with bird and bat droppings on soil under roosts. However, the infective stages of both organisms may be found in any accumulation of dry droppings and associated organic matter.
c. Personnel should also be aware of the possible dangers of other disease organisms associated with bird and bat excrement, discussed in para 2-2.
a. Mycosis, a fungal infection resulting in disease, is usually incurred by inhaling dusts, especially organic (decaying vegetation) dusts and dusts enriched with bird or bat droppings, which contain massive amounts of the disease organisms. These fungal organisms are ubiquitous in the environment and exposure to them is impossible to avoid. However, most humans are resistant to the amounts they encounter during normal activities.
b. The risk of contracting certain of these fungal infections is greatly increased by certain predisposing conditions such as an immunocompromised state (e.g., HIV infection, immunosuppressing medication, cancer, etc.), antibiotic therapy, surgical trauma, skin injury, and chronic disease. (See also the National Center for Infectious Diseases.)
c. The fungal disease organisms found in bird and bat droppings are listed below, including the source of the organisms, the methods of contraction, and the health effects.
(1) Cryptococcosis (Torulosis, European Blastomycosis).
(a) Source. Organic dusts, especially those contaminated with pigeon or bat droppinqs, are the most important source of the fungus, Cryptococcus neoformans, in the environment. C. neoformans has been found in as many as 84 percent of samples taken from old roosting sites. Up to 50-million colony forming units of C. neoformans have been found per gram of pigeon droppings.
(b) Contraction. Cryptococcosis is acquired by inhaling the yeast-like vegetative cells of the organism. These cells measure 1-3 microns in diameter and are easily airborne.
(c) Health Effects. Clinical manifestations of pulmonary infection are not characteristic and may be absent. The infection may disseminate to the central nervous system, resulting in cryptococcal meningitis (inflammation of the membranes of the brain and spinal cord), which is difficult to diagnose and fatal if not properly, and promptly, treated.
(a) Source. The causative agent of histoplasmosis, Histoplasma capsulatum, a dimorphic fungus (mold), is found in soils throughout the world. It flourishes by overwhelming other soil organisms when high relative humidity and optimum temperatures are present in soil that has been enriched by accumulated bird droppings for 3 or more years. It has also been found in bird and bat droppings not in contact with the soil. Once established in soil enriched by bird or bat droppings, H. capsulatum is difficult to eliminate even after the nutrient source is removed (Krzysik 1989).
(b) Contraction. Humans are infected by inhalation of the spores of this fungus which can be carried by wind and dust.
(c) Health Effects. Most infections produce no symptoms or only a mild influenza-like illness. However, pneumonia, blindness, and even death from a chronic infection are possible.
(3) Psittacosis (Ornithosis, Parrot Fever).
(a) Source. A rickettsial-like organism, Chlamydia psittaci, causes psittacosis. Approximately 150 cases are reported annually in the UK.
(b) Contraction. This disease is contracted by inhaling C. psittaci which is found in feathers and droppinqs from infected birds. Since the organism becomes less infectious with time, active roosts are of greatest concern. While the disease most often occurs in bird handlers, persons cleaning up bird excrement could contract the disease as well.
(c) Health Effects. Psittacosis is characterized by fever, headaches, and muscle pain, with or without obvious respiratory symptoms. Untreated cases, especially in older patients, can progress to pneumonia and/or generalized toxemia resulting in death.
(4) Other Fungal Diseases.
Paracoccidioidomycosis is a serious mycosis among workers in contact with the soil in tropical and sub-tropical regions from Mexico to Brazil. Although little is known about it at present, it is probably acquired by inhaling soil or fungus laden dust. Other fungal diseases found in soil and/or decaying organic matter--such as aspergillosis, coccidioidomycosis, blastomycosis, and sporotrichosis--are less likely to cause disease in humans.
