Dr. Maxwell "Mack" Lea, a veterinarian who served nearly 20 years as Louisiana's state veterinarian and spent decades caring for large animals in the Baton Rouge area, died Monday at the age of 79. Lea's work bridged private large-animal practice and statewide animal-health policy during a career that shaped livestock disease control in Louisiana.
From private practice to statewide work
A native of Baton Rouge, Lea began undergraduate studies at LSU before transferring to Oklahoma State University, where he earned his Doctor of Veterinary Medicine degree. He returned to Louisiana and spent about 20 years in private large-animal practice in Zachary, operating The Animal Center, which provided on-site boarding and care for cattle, horses and other livestock.
"He did a lot of field work,"
The hands-on approach meant Lea often traveled to farms to treat animals rather than always bringing them to his facility. His longtime involvement in large-animal medicine also led to leadership in the profession; he served as president of the Louisiana Veterinary Medical Association during his private-practice years and was "known and respected" among colleagues, according to his family.
State veterinarian and disease-control milestones
Lea retired from private practice in 1990 when Agriculture and Forestry Commissioner Bob Odom appointed him as the state's veterinarian. He held the position for 17 years, overseeing programs aimed at protecting livestock health across Louisiana.
One of the most significant achievements during his tenure was Louisiana's designation by the U.S. Department of Agriculture as Brucellosis Class Free for domestic cattle — a status reached through sustained efforts in vaccination, quarantine, testing and tracking.
Local ties and legacy
Family members say Lea valued both the animals he treated and the people he worked with. He kept close contact with cattlemen and other farmers even after leaving public service.

| Role | Location/Notes |
|---|---|
| Private practice | Zachary — The Animal Center, large-animal care (≈20 years) |
| State veterinarian | Louisiana Department of Agriculture and Forestry — appointed 1990, served 17 years |
Services for Lea are scheduled for Tuesday, July 21, at St. John the Baptist Catholic Church in Zachary, with visitation preceding the service.
Lea's death marks the passing of a veterinarian who moved between the barn and the policymaking table, a familiar path for many in Louisiana's rural communities where livestock health and agricultural economics remain tightly linked. His work on disease control contributed to safeguards for cattle producers across the state and reflects ongoing statewide priorities in animal health and biosecurity.
