Acute Pesticide Poisoning
Scientists at the University of the Philippines National Institutes of Health found that pesticide exposure results in abnormal levels of cholinesterase in cut-flower farmers. Certain pesticides are believed to attack the cholinesterase enzymes and may result in symptoms and conditions such as asthma, skin disorders, and multiple chemical sensitivity.
The study surveyed over 200 subjects to determine the adverse health effects of pesticides before conducting detailed laboratory tests. The recent effort set out to determine pesticide exposure, work and safety practices, individual and family illnesses, and cholinesterase levels. Pesticide application was most frequently associated with pesticide exposure through ocular and dermal entry. The factor most strongly associated with pesticide-induced illness was the use of a contaminated piece of fabric to wipe off sweat and the reuse of pesticide containers to store water. Containers should not be reused, but rather buried as they pose great health hazards and risks of contamination.
It is advisable to refrain from reuse of containers and to wash hands and skin thoroughly if accidental contact with pesticide is made. Avoid contact with areas sprayed and keep pets and children clear of them as well. The use of pesticides for prevention may be unnecessary and harmful to humans and pets. There are alternatives to pesticide use that can be employed if an infestation occurs.
One-fifth of the subjects studied had skin abnormalities and four-fifths had abnormal respiration and body temperatures. Fifty percent of had abnormally low cholinesterase levels. In addition, hematological parameters were also abnormal. Hemoglobin, hematocrit, and eosinophil count were all abnormal.
These study findings confirm results from earlier studies on the effect of pesticides in the body. There are many natural alternatives to pesticides that are safe, yet effective. Once cholinesterase levels are reduced, there is no known cure or treatment to counter the effects of the pesticides that will return cholinesterase to normal. Extreme caution should be exercised around pesticides, particularly in the home. Keeping a clean and neat home reduces odors, food crumbs, and debris that attract insects.
