Are wild birds being infected at bird feeders?

To date, there is no clear evidence to suggest that the recalled bird seed is associated with wild birth deaths. However, Salmonella bacteria can be spread through contaminated seed and from other sources at bird feeders. The bird seed can become contaminated when infected birds leave droppings that are ingested by healthy birds.

Platform bird feeders are the most common transmission sites. Tubular bird feeders are better at reducing transmission of the Salmonella bacteria, but birds can also be infected by eating spilled seed on the ground that has been contaminated by droppings. Bird feeder maintenance can help to reduce the spread of disease in wild bird populations.
