The word "toxic" means they can.
Natural
Not all mold is toxic. Certain molds excrete toxic compounds called mycotoxins which can be harmful or lethal. But not even all mycotoxins are harmful-penicillin is a mycotoxin for example. Another issue leading to health concerns with mold is how much a person is allergic to certain molds. But harmful molds often grow in indoor spaces that are dark and damp-such as the inside of walls that are not properly insulated, and it is the landlord's responsibility to keep the house mold free. Below is an article on toxic mold.
Mycotoxins are toxic compounds produced by certain molds that can contaminate food and feed. They can cause a range of health problems in humans and animals, such as liver damage, cancer, and neurological disorders. It is important to prevent their exposure through proper food storage and handling practices.
There are certain types of mold which are considered toxic. Certain molds excrete toxic compounds called mycotoxins which can be lethal-not all mycotoxins are lethal. It is best to get a residence or public building tested for toxic forms of mold. Not doing so can become a serious legal threat to landlords. Below is an article on toxic molds.
A thing (area, lake, stream, land, person) becomes contaminated when a toxic material is present in it. To De-contaminate the thing is to remove the toxic material
Mycotoxicosis refers to a toxic reaction in animals and humans caused by the ingestion of mycotoxins, which are toxic compounds produced by certain molds (fungi). These toxins can contaminate food and feed, leading to various health issues, including gastrointestinal disorders, immune suppression, and even cancer. Common sources of mycotoxins include grains, nuts, and fruits affected by mold growth. Prevention typically involves proper food storage and handling to reduce mold contamination.

Cleaning toxic soils is important to prevent harm to human health, wildlife, and the environment. Toxic soils can contaminate groundwater, crops, and food sources, leading to health issues. Cleaning toxic soils helps to restore ecosystems, protect biodiversity, and support sustainable land use.
Aflatoxins are naturally occurring toxins produced by certain molds, primarily Aspergillus species. The main types include aflatoxin B1, B2, G1, and G2, with aflatoxin B1 being the most toxic and carcinogenic. These toxins can contaminate various agricultural products, particularly grains and nuts, posing significant health risks to humans and animals. Aflatoxins are classified into two categories: those that are highly toxic (B1 and G1) and those with lower toxicity (B2 and G2).
Some molds produce allergenic spores or mycotoxins, which can cause allergic reactions or toxic effects in humans and animals. Additionally, certain molds can also break down organic matter, aiding in the decomposition process.
A broken fluorescent lamp can release mercury vapor, which is a toxic chemical that can contaminate the surrounding environment. It is important to carefully clean up and dispose of broken fluorescent lamps to prevent exposure to mercury.
Fermentation can be potentially dangerous if harmful bacteria or molds contaminate the fermentation process, leading to food poisoning. Certain types of fermented foods can also produce toxic byproducts if not prepared or handled correctly, which can lead to illness. Overconsumption of fermented foods high in histamine, such as aged cheeses or fermented meats, can also trigger allergic reactions in some individuals.
