Mycotoxin source and its exposure causing mycotoxicoses
1Department of Biology, College of Sciences, University of Hail, Hail, Saudi Arabia.
Abstract:
Mycotoxins are toxic compounds produced by fungi such as Aspergillus, Penicillium, Rhizopus, Fusarium spp., and mushrooms. They are present in the mycelium or in the spores of the fungus. They cause human health problems once ingested. This is common in countries with high ambient temperature and relative humidity such as in the tropical regions. The consumption of moldy food and feeds are injurious to people and animals. The linked acute and chronic diseases target organs in humans and animals. The clinical symptoms depend on the intrinsic toxic features of the mycotoxin, the quantity, and length of exposure. The diseases caused by ingesting mycotoxins are reffred as mycotoxicoses. Therefore, it is of interest to document known data on the mycotoxin source and its exposure causing human hazards leading to mycotoxicoses.
Insights
Mycotoxins from fungi cause health issues in humans and animals, particularly in tropical regions. Documenting mycotoxin sources and exposure is crucial for understanding and preventing mycotoxicoses.
Area of Science:
- Mycology
- Toxicology
- Public Health
Background:
- Mycotoxins are toxic secondary metabolites produced by various fungi, including Aspergillus, Penicillium, Rhizopus, and Fusarium species.
- These toxins are found in fungal mycelium and spores and pose significant health risks upon ingestion.
- Ingestion of moldy food and feed is a common exposure route, leading to acute and chronic diseases in humans and animals.
Purpose of the Study:
- To document known data on mycotoxin sources.
- To investigate mycotoxin exposure pathways.
- To understand the human health hazards leading to mycotoxicoses.
Main Methods:
- Literature review of mycotoxin-producing fungi.
- Analysis of environmental factors contributing to fungal growth (high temperature, humidity).
- Review of clinical data on mycotoxin-related diseases.
Main Results:
- Mycotoxins are produced by common fungi and are prevalent in tropical regions due to environmental conditions.
- Consumption of contaminated food and feed leads to mycotoxicoses, affecting various organs.
- Disease severity is dependent on toxin type, dose, and duration of exposure.
Conclusions:
- Mycotoxins represent a significant food and feed safety concern globally.
- Understanding mycotoxin sources and exposure is vital for mitigating public health risks.
- Further research and documentation are needed to combat mycotoxicoses effectively.
