COMPOSTING
(Environmental and Health Issues)
Presence of human pathogen
Pathogen reduction occurs in larger compost piles due to self heating
small compost piles, survival of pathogen is increased
Transmittal of human pathogen when materials such as plate scrapping are added to a compost pile
commonly pathogen found such as potting mixes
active compost can cause an allergic response
Health Effects
Respiratory system,
muscosal membrane irritation,

nausea
How to overcome?
Avoid certain input to the compost pile
raw poultry
pet feaces
meat wastes
managing your composting system
keep the system stay hot enough
Practise good personal hygiene when handling
Occupational exposure reduced through a combination of engineering controls, work practices, and personal protective equipments
Agitation of the compost
Odors are minimized when there is adequate oxygen,
Airborne particles emitted
Bioaerosol are particles of microbial
It includes live or dead bacteria, fungi, viruses, allergens, bacterial endotoxins, antigens, toxins, mycotoxins, glucans, pollen and plant fiber
Microorganisms are frequently absorbed onto dust particles
cause symptoms and/or illness
become sensitized to some bioaerosols through repeated exposure
Concentration of bioaerosol downwind of outdoor composting facilities are elevated
Infections
gastric
Aspergillosis
