Be careful with that stuff Herbert ...
Thank you, Orchid.
I'll be using a surgeon's mask while I apply it to the feathered girls (if I can catch them).
But here are a few notes off the Web with regard to the health risks of breathing in
Food Grade Diatomaceous Earth :
"Inhalation of diatomaceous earth may cause temporary respiratory irritation such as sneezing, coughing, difficulty breathing, eye, nose and throat irritation or bloody nose. This means that workers exposed to crystalline silica on a daily basis for many years may be at risk, but casual contact is not likely to be hazardous.
"After inhalation of amorphous diatomaceous earth, it is rapidly eliminated from lung tissue. However, crystalline diatomaceous earth is much smaller, and it may accumulate in lung tissue and lymph nodes. Very low levels of crystalline diatomaceous earth may be found in pesticide products.
Is diatomaceous earth likely to contribute to the development of cancer?
When mice were forced to breathe diatomaceous earth for one hour each day for a year, there was an increase in lung cancers. When rats were fed silica at a high dose for two years, there was no increase in cancer development.
"When guinea pigs were forced to breathe air containing diatomaceous earth for 2 years, there was slightly more connective tissue in their lungs. When researchers checked before the 2-year mark, no effects were found".
