Day 4 - Mould & Mycotoxins
We’ve long known about the dangers of eating mouldy food, so food standards limit mycotoxin contamination in grains and other food for this reason. But there is far less recognition of how mould and mycotoxins cause illness when inhaled. In a water-damaged building, a phenomenon called amplification occurs where certain moulds and bacteria flourish and have the resources to produce significantly more biotoxins. When these toxins are inhaled over time, people living or working in those buildings can become unwell. Some of the subsequent health issues that arise are allergy, fungal infection, toxicity, and an overactive innate immune system called CIRS. In the latter case, the immune system can detect but not remove biotoxins from the body, so the body becomes more and more inflamed over time, causing the chronic inflammatory response that CIRS is named for.
