(Portland, OR) -- No injuries are reported after a four-alarm fire tore through a 100-year-old commercial building in North Portland. Portland Fire & Rescue says nearly 100 firefighters responded to the blaze yesterday afternoon at the noodle-making business Shin Shin Foods on North Kerby Avenue near Interstate-5. The fire burned through the roof, forcing crews to fight it defensively from the outside. They used master streams to dump two-thousand gallons of water per minute on the fire. Crews stayed back from the building in the event the walls might collapse. Firefighters remained on the scene through the night.
