Poultry dust is a mixture of bird feed, bedding material (eg wood shavings/shreds or straw), faeces, feathers and dander (dead skin), dust and stored product mites, ectoparasites, and micro-organisms such as bacteria, fungi (moulds) and endotoxins (cell wall components of bacteria) (1). It is generated by the birds and operatives movement in the sheds, grinding down the feed, bedding and droppings. (2)

Poultry dust is present as airborne particulate matter, diameter less than 10 microns (often referred to as <PM10), and is classified as hazardous to health. There is increasing concern about the even smaller micro particles with a diameter less than 2.5 microns (<PM2.5) because particles of this size are able to reach the lungs' alveoli.

This dust is emitted from the sheds by forced air extraction fans and vented into the surrounding atmosphere and locality as a bio-hazardous plume. The particle concentration in this plume will become particularly high when the sheds are cleaned out. Dust will also be generated outdoors by the hens making dust baths in the paddocks.

This dust has long been recognized as the reason why poultry workers frequently suffer from asthma and other respiratory diseases (1). However, recent research (3) has shown that it is not just poultry workers at risk. It was found that residents within the locality (1 kilometre) of industrial poultry units had an 11% increased risk of developing community-acquired pneumonia (CAT) .

We believe that there should be a moratorium on planning approval for IPUs until the health issues are better understood.
