Salsa is supposed to bring the heat to a chip-and-dip combination. But at a Texas factory, it's the tortilla chips that are on fire. Earlier this month, firefighters responded to the "spontaneous combustion of tortilla chips" twice in three days at an Austin factory, the Austin American-Statesman reports. The factory was trying a new waste management method which "suffice it to say, didn't work out so well," the fire department said on Facebook.
