Bird flu: a simple biosecurity checklist for small poultry farms
In March 2025, Bangladesh reported its first highly pathogenic bird flu outbreak on a farm since 2018. On a farm in Jessore district, 1,900 of 3,978 birds died, and the rest of the flock was culled. For a small farmer, one outbreak can wipe out a year's income in a week.
There is no cure for bird flu in chickens. Protection means keeping the virus out. Most of these steps cost little or nothing.
The biosecurity checklist
- One gate, kept shut. Only people who work on the farm go inside the sheds.
- A foot dip with disinfectant at the shed door, changed every few days.
- Separate boots and clothes for the shed, never worn to the market or another farm.
- Wash hands before and after handling birds.
- Keep wild birds, ducks and crows away from feed and water; cover feed stores.
- Do not keep ducks and chickens together, and keep backyard birds away from the farm.
- Buy chicks only from registered hatcheries, and keep new birds apart for two weeks.
- Clean and disinfect the shed between batches, and dispose of litter away from the farm.
Warning signs
- Many birds dying suddenly, often within a day or two.
- A sharp drop in eggs, or soft-shelled eggs.
- Swollen head, blue or purple comb and wattles.
- Birds sitting still, not eating or drinking.
If birds start dying
- Report it to your Upazila Livestock Office at once. Early reporting protects your neighbours and your next batch.
- Do not sell, eat or give away sick or dead birds, and do not throw them in rivers or fields.
- Do not handle dead birds with bare hands. Bird flu rarely infects people, but it can.
- Stop all movement of birds, eggs, trays and people off the farm until an officer has visited.
