Totowa Fire Marshal Allen Del Vecchio tells WABC-TV  that he felt the blast from Pharmachem Laboratories in Totowa at his house a mile away.

Pharmachem produces ingredients that flavor foods. Workers tell the TV station they had just started on a new recipe for eggnog when it somehow ignited. The two workers suffered minor injuries.

Del Vecchio says given the severity of the blast, he's surprised more workers weren't hurt. The entire rear of the building was completely blown out.

An investigation into the cause of the explosion is underway.
