MISSISSIPPI STATE, Miss. — Biosecurity is a process to prevent disease from entering your farm or poultry flock. Avian influenza (AI) makes it extremely important for commercial producers and backyard flock owners to protect their flocks by having a strong biosecurity program in place. There are two main pathways for disease transmission in most poultry flocks:
1. Direct transmission (physical contact between infected and healthy individuals)
2. Indirect transmission (disease agent is carried to susceptible individuals) by:
- humans
- feed
- water
- environment (contaminated pens, pastures, or water sources)
