Oregon OSHA only has jurisdiction over workplace safety and health issues.
If your complaint relates to enforcement of minimum wage or collection of wages owed, go to the Bureau of Labor and Industries, Wage and Hour Division: http://www.oregon.gov/BOLI/WHD/pages/index.aspx
For discrimination complaints, go to the Bureau of Labor and Industries, Civil Rights Division: http://www.oregon.gov/BOLI/CRD/pages/index.aspx
If you have a food safety concern, those issues are usually best addressed by a local county health department. Both the Oregon Health Authority and the Oregon Department of Agriculture regulate food borne illness: http://public.health.oregon.gov/HealthyEnvironments/FoodSafety/Pages/index.aspx
