Trichuris suis, the swine whipworm, can cause severe diarrhea, anorexia, and performance losses owing to reduced average daily gains and decreased feed efficiency. Severity of disease and impact on performance are related to infectious dose or concurrent infections. Trichuris suis is
present in modern swine operations, but is an uncommon and perhaps neglected diagnosis. This paper describes an incidental finding of T suis in a finishing facility, with negligible impact on production, but demonstrates the continued presence of the parasite in modern swine production. This paper also provides a current review of T suis, trichuriasis, and control strategies.
