Conjunctivitis, often called “pinkeye,” is a condition in swine marked by inflammation of the conjunctival membranes of the eye. It can stem from both infectious causes and non-infectious factors such as excess dust or ammonia, high hydrogen sulfide levels, and bedding materials that trigger irritation.
A new resource from the Iowa Pork Industry Center, Conjunctivitis in Swine, outlines how producers can recognize the disease and steps to take once it appears.
According to Iowa State University Extension and Outreach swine veterinarian Chris Rademacher, who co-authored the publication, the issue is most frequently seen during the late nursery through early grow-finish stage and is also a common concern among exhibition swine producers.
“Both prevalence and severity in a group depend on the route of infection and transmission,” Rademacher explained. “For example, Chlamydia suis is a common agent, yet other viruses such as PRRS, Influenza A and pseudorabies should be ruled out with veterinarian assistance.”
Rademacher added that non-infectious triggers, including irritant bedding, transportation stress, or high concentrations of dust and ammonia, may also play a role.
When conjunctivitis is identified, Rademacher recommends that producers examine housing conditions, collect swab samples, and coordinate with their veterinarian to determine appropriate actions.
Iowa State researchers are currently seeking cases to collect samples for a study on the most frequent pathogens. Producers with potential cases may contact Dr. Megan Hindman at mpieters@iastate.edu
