The National Animal Health Laboratory Network (NAHLN) says 266 new cases of porcine epidemic diarrhea virus (PEDV) were confirmed the week ending March 22, bringing the grand total to 5,017, which reflects a minor downward revision (5 cases) from the previous week's tally. PEDV has been confirmed in 27 states, which is unchanged from the previous week.
Iowa, the No. 1 pork-producing state in the nation, continues to lead the number of total confirmed cases at 1,646, up 54 from last week. Minnesota follows with 793 confirmed cases, up 40 from last week and North Carolina is third of the list at 518 cases, up 16 from last week.
