On-farm diagnostics are increasingly critical in poultry production because they allow producers to detect pathogens early, often before clinical signs emerge, and to quantify pathogen load with precision. Tools such as serotyping provide insight into which Salmonella strains are present and where they originate within the production system. With this detailed understanding, producers can move beyond broad interventions to targeted strategies that address the root cause of contamination.

When diagnostic data is integrated into a broader program – including vaccination, insect control, feed additives and biosecurity – producers can reduce pathogen prevalence at multiple points in the production chain. This not only improves flock health and welfare but also directly supports food safety by lowering Salmonella levels before birds reach processing. Ultimately, diagnostics help align on-farm practices with regulatory expectations and consumer demand for safe, wholesome poultry products.
