We would also like to thank the small group of poultry and pork industry stakeholders, diagnostic labs, and state and federal veterinary medical officials that participated in an initial review of the draft version of this case study report on May 7, 2019 at the Iowa Pork Producers Association office in Clive, IA. Their provision of insight, suggestions, and associated dialogue were useful in our efforts to complete this case study.
