Hypothesis
The implementation of Small Food Workshops Management Regulations (SFWMR) will reduce aflatoxin B1 contamination in home-made peanut oil and improve liver function among residents in high-consumption areas.
Conclusion
The implementation of SFWMR significantly reduced aflatoxin B1 contamination in home-made peanut oil and improved liver function among residents in Guangzhou.
Supporting Evidence
- The implementation of SFWMR was associated with a significant reduction in AFB1 concentrations in HMPO.
- Residents in high-HMPO-consumption areas showed a decrease in liver function abnormalities after SFWMR implementation.
- Subgroup analysis indicated significant improvements in liver function for females and individuals aged 60 years or older.
Takeaway
New rules for small food workshops helped make peanut oil safer by reducing harmful toxins, which is good for people's liver health.
Methodology
The study used high-performance liquid chromatography to measure aflatoxin B1 levels in home-made peanut oil and analyzed liver function data from health center records using interrupted time series and mediation analyses.
Potential Biases
The study's ecological design limits the ability to establish causality.
Limitations
The study may have selection bias due to reliance on health examination data and the potential for false positives in liver function tests.
Participant Demographics
The study included 21,828 residents, with 52.95% females and 47.05% males, and 71.01% aged 60 years or older.
