It would help if the composts that had L. longbeachia were identified. As it is, all are suspected. It is like saying there is horsemeat in some burgers, and then not identifying which supermarket or product.
Were these made from Peat,bark, coir, or recycled green waste?
Australian products have warnings on, but have a different composition, they have more sawdust in, which apparently is more likely to harbour the pathogens.
Wouldn't it be better if any suspect materials were sterilised before packaging?
Bonemeal is usually sterilised before being packaged for garden use, because of the possibility of anthrax being passed on.
