A fungal contaminant refers to unwanted fungi that can invade various environments, including food, soil, and indoor spaces. These fungi can lead to spoilage, health issues, and damage to materials. Common types of fungal contaminants include molds, yeasts, and mildews, which thrive in warm, damp conditions. Fungal contaminants can produce spores that spread easily through the air, making them difficult to control. They can cause allergic reactions and respiratory problems in sensitive individuals. Proper hygiene, ventilation, and moisture control are essential in preventing fungal contamination in homes and workplaces.
