Coggins Test Requirements
Traveling out of and into Pennsylvania
Proof of a negative Coggins test is required for horses traveling interstate and for some intrastate movement. As of 2022 all states require proof of a negative Coggins test for horses crossing a state line. For Pennsylvania it is required that all horses entering the Commonwealth be accompanied by a negative Coggins from within 12 months prior to requested date of entry. Foals entering the Commonwealth do not need a test if they are under six months and accompanied by a dam with a negative test result.
Pennsylvania and many other states also have additional requirements for interstate travel such as a current Certificate of Veterinary Inspection. Be sure to identify both destination states and home state requirements before leaving to ensure you can enter new states and reenter your own without issue.

Horse Shows and Other Equine Facilities
Many horse shows and facilities require that a negative Coggins test be provided for the horse to enter the premises or participate in the event. It is encouraged that all horse shows and facilities require proof of a negative Coggins test from competitors upon entry. Similarly horse owners are encouraged to only participate at shows that have this requirement. Horses that are being sold entering sales or newly purchased should also be required to have a current negative Coggins test.

Conclusion
Obtaining a Coggins test annually is imperative to reduce the risk of EIA transmission. As most carriers of EIA are asymptomatic testing can help identify carriers and prevent transmission to other horses. Anytime you plan to travel with your horse make sure you explore documentation requirements for that state facility and event before departing. Additionally make sure that a current negative Coggins test is available for any horse you plan to purchase or sell.
