(Portland, OR) -- Illegal food carts continue to appear on Portland streets, even after being marked as unlicensed. The Multnomah County Health Department says these are small red carts brought in from outside of the region. They don't have food handling equipment, hand washing facilities, clean water or refrigeration. The fuel sources are also a risk of fire. The County has placed stickers on them showing they're unlicensed, but the vendors cover them up. Since last summer, inspectors have seen an increase in illegal food carts.
