Study Notes
Fungal Species and Mycotoxins
- Aflatoxins and ochratoxin A are produced by Aspergillus species.
- Mycotoxins from animal-derived products mainly enter human exposure through consumption of contaminated food.
Toxins Produced by Fusarium
- Fusarium species produce mycotoxins such as trichothecenes, zearalenone, and fumonisins.
- Toxin-producing Fusarium fungi are primarily found in tropical and subtropical regions, which include parts of Africa, Asia, and the Americas.
Important Contaminants
- Mycotoxins are significant contaminants due to their prevalence in various products.
- Acrylamide and furan are categorized as process contaminants created during food processing and cooking.
Heavy Metals
- Heavy metals like mercury and lead are persistent environmental contaminants affecting food safety.
- They enter the food chain through various pathways, including soil, water pollution, and accumulation in the food web.
Health Effects and Legislation
- Exposure to lead can lead to developmental and neurotoxic effects, particularly in children.
- Mycotoxins and heavy metals are regulated by legislation in many countries to safeguard public health.
Hormones in Agriculture
- The primary source of oxytocin in plants is linked to plant-based diets; however, it is commonly associated with animal care practices for milk production.
- Growth hormones are utilized in the beef cattle industry to enhance growth rates and feed efficiency.
Administration of Growth Hormones
- Hormones are typically implanted in the ear or under the skin of cattle to facilitate better performance and growth.
Toxicants in Agriculture
- Mycotoxins, alkaloids, and other compounds are classified as toxicants arising from the metabolic processes of various organisms.
- Foods like potatoes (glycoalkaloids) and comfrey (pyrrolizidine alkaloids) may contain toxic alkaloids that pose health risks to humans.
Cassava Processing
- Cassava must undergo a process called soaking or fermentation to eliminate cyanogenic glucosides, making it safe for consumption.
