DR and other media outlets have now turned their attention to mould, first with "Kontant" the other day, and most recently with headlines like this:

In this context, a few things need to be clarified.
Basically, healthy people do NOT die from mould, we as a species have evolved in an environment where we inhale mould spores with every breath. They are everywhere and because they are microscopic, they float around in the air and end up in our lungs - over and over again.
The places where we come into contact with the most mould spores (besides in a mould-infested apartment) are outdoors and worst during the hot, humid summer months. Figures from the Asthma and Allergy Association and DMI show that outdoor air can contain up to 60,000 spores per cubic metre of air - this means that during a walk outdoors during these months, we breathe in up to 300 spores per minute.
In reality, these little guys should be thriving in our lungs - there's high humidity and plenty of food. However, they are NOT, because our immune system recognises them and kills them before they get started.
In some people, the immune system can go crazy and react violently (and inappropriately) to mould - those who are mould allergic (1-2 % of the Danish population) react with the classic hay fever symptoms - sniffles, watery eyes, difficulty concentrating and general discomfort - but they do NOT die from it!!!!!.
So for all "ordinary" people, mould is harmless!
If you are NOT normal, i.e. if your immune system is proven to be weakened or completely compromised - this is typically the case for patients who have received a new organ through transplantation, and for people undergoing harsh chemotherapy, you may be at risk of contracting a mould infection.
If the immune system can't handle mould spores that land in the lungs, they will grow there in the lovely moist, warm, nutrient-rich environment. There may also be mould spores that land elsewhere in the body through surgical wounds etc. and they can then thrive wherever they happen to land.
These are the cases that DR has now made a headline, and the mould infection has to be treated with antifungal agents.
The problem is (as with antibiotics) that the agents used are actually developed as plant protection products, a large group of which are the so-called "triazoles". They are used everywhere in agricultural production to prevent the crop from being destroyed by mould. There is now some debate as to whether this widespread use actually makes some mould species resistant to the fungal toxin, making it difficult to treat people with compromised immune systems who have contracted a fungal infection.
As for Protox's "mould" products, neither contains ProtoxHysan, ProtoxBiox, ProtoxMille or ProtoxProtect triazoles.
Therefore, when we remove mould growth with ProtoxHysanwe do it with an agent that CANNOT create resistance - chlorine dioxide, and when we then prevent with ProtoxProtectit contains the fungal toxin IPBC, which is NOT used for human medicine.
Our approved wood preservatives ProtoxAquagrund and ProtoxSvampPro contain small amounts of Propiconazole, which is a triazole, as this is necessary to comply with the requirements of the Danish Environmental Protection Agency to approve them as "wood preservatives". As these products are NOT used to combat mould infestation - as is the case in agriculture - but to prevent attacks by wood-degrading fungi, their possible influence on the development of resistance in mould is extremely theoretical.
