Screwworm Could Create a Financial Shock Ranchers Cannot Ignore

The confirmed detection of New World screwworm in the United States should be viewed as more than an animal health emergency. It is a financial warning for ranchers, livestock producers and the broader beef supply chain.

USDA confirmed the parasite in a bovine in Zavala County, Texas, on June 3, marking the return of a pest that had been eradicated from the United States for decades. New World screwworm larvae feed on the living tissue of warm-blooded animals, causing severe damage, infections and death if cases are not treated quickly.

The economic stakes are significant. USDA estimates its federal response could exceed $1 billion.

For ranchers, losses from screwworm may not come from one infected animal. They may come from the chain reaction that follows quarantines, movement restrictions, veterinary treatment, labor-intensive monitoring, delayed sales, lower weights, market volatility, and uncertainty among buyers.

Even operations without confirmed cases could face financial pressure if they are located near a control zone or if regional cattle movement is restricted. When animals cannot move on schedule, cash flow changes quickly. Calves may miss a key sale window. Feed costs can rise. Lenders may ask harder questions. Producers may be forced to make decisions under pressure.

This comes at a difficult time for the beef industry. The national cattle herd is already at a 75-year low after years of drought, high input costs, and beef prices have remained elevated. A biological threat layered on top of tight supplies creates a level of risk many ranchers have not had to plan for in decades.

Traditional insurance remains essential, but many policies are not designed to cover every financial consequence of a disease or pest event. Livestock mortality coverage, property insurance, and liability policies may help in specific situations, but they may not fully address business interruption, regulatory shutdowns, added labor, biosecurity expenses, treatment costs or market disruption.

That is why ranchers should use this moment to review their full financial risk strategy.

An 831(b) Plan can be one tool in that broader conversation. Under Section 831(b) of the tax code, qualifying businesses can form a small insurance company to insure certain risks that are uninsured or underinsured in the commercial market. When properly structured, an 831(b) Plan allows a business to set aside premium dollars into a regulated insurance structure designed around defined business risks.

For agricultural operations, that may include certain business interruption risks, supply chain disruptions, disease-response costs, regulatory restrictions, deductible gaps or other exposures identified through a formal risk assessment.

An 831(b) Plan is not a substitute for strong herd health protocols, veterinary care, biosecurity, traditional insurance or government response efforts. It is also not something producers should attempt to create after a crisis has already arrived. The value comes from planning ahead, identifying gaps and building a financial reserve structure before disruption hits.

Screwworm is a reminder that old threats can return, and that modern agriculture is exposed to risks that move faster than many balance sheets can absorb. A single confirmed case can change market psychology. A regional outbreak can change operations. A national response can change an entire sector’s financial outlook.

Ranchers are already skilled at managing visible risks. They monitor weather, cattle health, forage, equipment, and markets every day. The next step is making sure their financial risk planning is just as disciplined.

The goal is not to predict every crisis. The goal is to be prepared when one arrives.

Screwworm may be contained. It may not become a widespread disaster. But the potential financial fallout is large enough that ranchers should not wait to find out. Now is the time to review coverage, identify uninsured exposures and consider whether tools such as an 831(b) Plan belong in a broader risk management plan.
