An air quality alert covering the entire state of Minnesota continues on Thursday, marring otherwise fairly ideal weather conditions.

Data suggests that air quality in Minneapolis ranked worse than the air in Egypt, South Korea and China. Minneapolis has the fifth worst air quality in the world, according to an air quality monitoring platform that reported its latest findings Saturday.

On Saturday, an event billed as the upper Midwest’s largest gathering of food trucks was in Minneapolis, on a day when Canada’s wildfire smoke made it harder for some people to breathe.
