Horticulturalists have been using peat for years on very bacteria susceptable without steralising it. Loam is
the growing media people should be wary of. This is because peat is a naturally sterile media. The only way it
will be contaminated is if you store it a pile on the ground open to the elements ( some daft people do! )or by
buying a bag that is split. This goes for perlite and vermiculite too.
