Aliso Viejo, California, USA. 25th Apr, 2014. Sriracha hot sauce products on sale in a California supermarket. Huy Fong Foods Sriracha plant in Irwindale that produces the popular Sriracha hot sauce has 90 days to contain its fumes after a decision by a California city council to label it a public nuisance. The Irwindale City Council's resolution enables officials to make changes if the smells continue after the factory's deadline has past. The factory had been working with the South Coast Air Quality Management District on the filtration system since complaints from residents first happened.
