Do you trust new surveillance technologies to improve livestock health management in the U.S. swine industry?
Lincoln-based startup DARO recently secured $2.5 million to scale its swine surveillance technology, which detects the PRRSV virus nearly four days earlier than traditional methods. The company is now planning to expand laboratory capacity to support broader adoption across the U.S. swine industry.
Why it matters
Early detection of pathogens like PRRSV is critical for swine producers, as it provides a wider window to adjust biosecurity protocols and manage animal movements before a breakout spreads. This expanded surveillance capability offers operators a more proactive tool for maintaining herd health and mitigating the significant financial risks associated with viral outbreaks.
DARO reported that its environmental surveillance detected PRRSV 3.91 days earlier than oral-fluid testing in all 11 nursery rooms studied. The company successfully raised $2.5 million in a September 2026 funding round to scale its laboratory operations.
The players
DARO
A Lincoln-based startup developing environmental surveillance technology for the swine industry.
The Combine
An incubator providing support and resources to early-stage technology companies.
The details
DARO's method involves barn employees wearing specialized shoe covers while moving through pens to collect biological material, which is then processed using molecular testing at the company's Lincoln facility. By capturing pathogens from the environment rather than relying on animal-specific fluids, the system identifies viral presence before symptomatic infection occurs. This technical shift allows producers to implement containment strategies earlier in the disease cycle, reducing the potential for facility-wide contamination.
Timeline
Early 2024: DARO began establishing its laboratory operations in Lincoln.
September 2026: The company closed a $2.5 million funding round.

Market Landscape
DARO's surveillance model departs from the industry standard of PRRSV oral-fluid testing by moving diagnostics out of the animal and into the physical environment. This shift aligns with broader trends in agricultural technology aimed at replacing manual, reactive health checks with automated, proactive monitoring.
Swine producers should evaluate whether environmental surveillance can replace or augment current oral-fluid testing schedules to improve biosecurity lead times. Operators looking to manage herd health costs should track the availability of DARO's expanded laboratory capacity as a potential risk mitigation resource.
The takeaway
Early pathogen detection is increasingly relying on environmental monitoring to provide actionable data for herd management. Operators should review their current diagnostic turnaround times and compare them against these surveillance benchmarks to determine if their biosecurity plan requires an upgrade.
