that's a given, you have to swab it with alcohol no matter what, but I am talking about the air you inject into the vial to create pressure. that air is the same air you breath, your dog breaths, and God knows whatever else the air is carrying goes into the vial, that's what I am thinking is contaminating the vial. I am not talking major contamination, I am sure if you drink the oil it won't do anything but when its injected in your
veins that's where is becomes touchy.
BTW, don't use the oil for your salad dressing, I was just trying to make a point
