Hypothesis
What are the levels of aflatoxin contamination in fresh and sun-dried meat in Nigeria?
Conclusion
Meat sold in Nigeria is contaminated with various fungi species, including potentially harmful mycotoxins, which poses health risks to consumers.
Supporting Evidence
- Eighteen fungi species belonging to eight genera were identified in the meat samples.
- Aflatoxins B1, B2, G1, and G2 were detected in all samples analyzed.
- Sun-dried meat samples showed higher contamination levels compared to fresh samples.
- An exceptionally high aflatoxin content was found in all kidney samples.
- Potential health hazards include aflatoxicosis and immune function suppression.
Takeaway
This study found that meat in Nigeria can have harmful toxins that can make people sick, so it's important to check the meat we eat.
Methodology
Eighty meat samples were collected from five major markets and analyzed for mycotoxin contamination using plate count, micromorphological methods, and Thin Layer Chromatography.
Limitations
The study may not represent all regions of Nigeria as it was limited to specific markets in Oyo State.
Participant Demographics
Samples were collected from various markets in Oyo State, Nigeria.
