Mould: Ugly, yes. But the health consequences of inaction are uglier.
Gizmodo explains: “A common mould called Aspergillus, when inhaled by particularly susceptible people, can infect the lungs and spread throughout the body. Other moulds that grow in our foods can produce toxins that sicken us quickly or increase our risk of cancer over time.”
As Jim’s Building Inspections also explains: “Mould produces microscopic particles which can become airborne. These particles can be inhaled by humans and animals—which can cause severe health problems. People with compromised immune systems face an increased risk from mould particles.”
