CHICAGO — Hours after it started,  firefighters remain on the scene of a massive fire on the city’s Northwest Side. The fire is now under control but Metra is still reporting delays.

Crews responded to the fire at Newly Weds Foods factory in the 4100 block of West Wrightwood Avenue around 4 p.m. in the city’s Hermosa neighborhood. It was quickly elevated to a hazmat situation and ultimately reached a 5-alarm status, the highest a fire can go.

The employees inside self-evacuated and no one was injured.

The company is located in 68 countries and has about 3000 employees. They make bread crumbs and batter.

Officials said the fire started in the cooking area where there was bread crumbs and cooking oil and it spread very quickly through the roof which was made of wood. The offices were not damaged, but the cooking area was completely destroyed and the roof collapsed.

A fireman sprained his knee but is expected to be fine.

Train service was halted on Metra’s Milwaukee North line, but it has since been restored with extensive delays.
