The article talks about the situation in Black Hawk County and northeast Iowa in general. Here's an excerpt from the part about Tyson:
Egbuonye (BH County Health Director) thanked Tyson for allowing health officials inside its facilities last week and talked about measures the company implemented to prevent coronavirus spread.

We have witnessed the difficulty of social distancing in Tyson, Egbuonye said. Its a problem that I truly believe is very difficult for food production facilities.
Employees of Tyson had been saying as much, telling The Courier this week they were terrified coronavirus had been spreading amid inadequate protections by the company.
There was clearly more than could have and should have been done, Sheriff Tony Thompson said. Today, our entire countywide health care delivery and virus response system is paying the price for those lapses in protocol.
Any employee of Tyson in Waterloo experiencing symptoms was now eligible for coronavirus testing at MercyOne, UnityPoint-Allen Hospital and Peoples Clinic. County officials received 1500 new tests kits from the state to help facilitate that.
