Caribbean countries are ramping up preparedness measures against African swine fever, according to a report from National Hog Farmer. The regional push comes as the viral disease continues to circulate in the Americas, keeping veterinarians and pork producers across the hemisphere on alert.

African swine fever is a highly contagious viral disease of pigs that carries near-100% case fatality in naïve herds. It does not affect humans, but an outbreak in a previously free country triggers immediate trade closures and mass culling — which is why preparedness, rather than response, dominates the agenda for island nations with small but economically significant pork sectors.

For the Caribbean, the stakes are twofold. First, the region sits within reach of the Dominican Republic and Haiti, where ASF has been endemic since its detection there in 2021 — the first occurrence in the Americas in roughly 40 years. Second, Caribbean nations depend heavily on pork imports, and porous ports of entry make biosecurity enforcement a logistical challenge.

The National Hog Farmer report indicates the current preparedness effort centers on strengthening regional coordination and readiness. For food-animal practitioners in the region, that translates into concrete tasks at the farm level: reviewing and tightening on-farm biosecurity protocols, ensuring swill feeding is eliminated as a transmission route, training producers to recognize and report suspicious mortality quickly, and confirming that diagnostic sample pathways to reference laboratories are established before an outbreak, not during one.

Public-health implications remain limited in the direct sense — ASF is not zoonotic — but the food-security dimension is real. Many Caribbean states rely on smallholder and backyard production, where a single introduction could wipe out household-level protein supply and force costly import substitution. Rapid detection and stamping-out also carry occupational considerations for veterinarians and responders handling large-scale culling operations.

For the United States, the Caribbean situation functions as an early-warning buffer. USDA and Customs and Border Protection have maintained heightened surveillance of passenger and cargo traffic from ASF-affected islands since 2021, and a better-prepared Caribbean reduces the probability of the virus reaching U.S. shores through regional spread. American practitioners can expect the standard advisory to hold: no pork products from affected regions, strict attention to international travelers, and immediate reporting of high-mortality swine events to state animal health officials.

There is no commercially available vaccine against ASF in the U.S., and no treatment exists, leaving biosecurity and early detection as the only effective tools — a reality that places veterinary oversight at the center of any national preparedness plan.

The Caribbean preparedness drive signals a regional recognition that the hemisphere's ASF status remains fragile, and continued investment in surveillance and coordination will determine how quickly the region can detect — and contain — its next introduction.
