Mycotoxic mold and mold spores are those containing toxins in the cell wall. These types of mold can cause serious health problems in humans and animals. These molds range from short-term irritation to immunosuppression, to cancer and even death.If toxic molds are identified, it is suggested that you seek advice from an Industrial Hygienist or other mold professional for guidance.llergenic mold and mold spores are normally not dangerous to humans in low amounts, but they cause allergic or asthmatic symptoms.
