Hanging seed feeders typically retain the food within a clear plastic tube and this means that there is a very low risk of the food becoming contaminated with droppings.

Bird tables, where birds actually stand on and amongst the food, have a greater risk of contamination. Whilst this implies that hanging feeders are better from a disease prevention point of view, it is worth remembering that many species are unable to use hanging feeders and that, with good hygiene practice, bird tables or ground feeding trays are just as safe.

When choosing a feeder or bird table, look for one that reduces the risk of contamination and keeps the food dry. If food becomes damp, then it is likely to be more susceptible to moulds and contamination by other harmful agents.

Some mesh peanut feeders leave the peanuts open to the elements and the nuts may become damp and deteriorate more quickly than other types of food held in tube feeders. This means that you should pay particular attention to the peanuts you provide to ensure that they are fresh and safe for the birds. One of the best ways to ensure this is to only put out a small quantity of peanuts so that fresh ones have to be put ut every few days.
