(Portland, OR)  --  Residents who live near Bullseye Glass Company in Southeast Portland are being urged not to eat any produce grown on their property.  Officials with the Oregon Health Authority and the Department of Environmental Quality say those who live within a half-mile of the facility should refrain from eating fruits and vegetables grown on their property.  That's after air-quality testing in the area found elevated levels of arsenic and cadmium, toxic materials used in the manufacture of glass.  Bullseye Glass has since voluntarily stopped using the materials.
