(Portland, OR) -- Oregon food cart owners face new rules that take effect this month. The rules were established in 2020, to give owners time to comply. The rules require all equipment to be physically attached to the food cart. When items sit on the ground they create gathering places for insects and rodents. Most food carts are also required to have on-board drinking and wastewater tanks. Food carts can connect to water and sewer, if it's available, but they still need to have the tanks. Food carts that don't comply won't be shut down immediately as long as they're working to solve the problems.
