I could not imagine what you would use it for in food,but the msds says it does not cause problems ingesting it. I will put in what it says about inhaling and drop it . You decide what is best for you.
It is like I try to get my guys to wear welders safty googles in the room, they think its a pain in the ass to go back and get them. Wait 20 years the shit adds up.

Potential Health Effects
----------------------------------
Inhalation:
Causes dryness and irritation to the respiratory tract. Symptoms may include coughing, sore throat, breathing difficulty (dyspnea), and wheezing. Excessive inhalation may cause decreased pulmonary function, lung damage and silicosis. Acute silicosis is manifested by dyspnea, fever, cough and weight loss. Severe respiratory symptoms may lead to death.
Ingestion:
No adverse effects expected.
Skin Contact:
Causes irritation with dryness and abrasion.
Eye Contact:
Causes irritation, redness, and pain.
Chronic Exposure:
Prolonged inhalation exposure may produce silicosis. Chronic symptoms include cough, dyspnea, wheezing, increased susceptibility to tuberculosis, decreased chest expansion, and repeated nonspecific chest illnesses. Progressive respiratory and cardiopulmonary impairment may be fatal. Chronic inhalation of crystalline silica is a lung cancer hazard.
Aggravation of Pre-existing Conditions:
Persons with pre-existing respiratory or cardiopulmonary problems may be more susceptible to the effects of this substance.
