Aflatoxin Contamination in Commercial Eggs from Lima Trade Systems

A study in Ate, Lima quantified aflatoxin contamination in 90 commercial egg samples from supermarkets, traditional markets, and backyard poultry. The dataset records the presence and concentration of aflatoxin subtypes B1, B2, G1, and G2, measured via serological screening and competitive ELISA.

Use Cases

• Analyze aflatoxin concentration levels across the three trade systems (supermarkets, traditional markets, backyard poultry) to identify contamination risk factors.
• Model the dichotomous presence (Positive/Negative) of total aflatoxins as a function of the trade system source.
• Compare the distribution of measured aflatoxin concentration (nanograms per gram) between samples from different trade channels.

Strengths

• Data includes 90 egg samples collected for analysis.
• Measures both a dichotomous presence variable and a continuous concentration variable for aflatoxins.
• Focuses on eggs with undamaged shells to accurately reflect products accessible to consumers.

Limitations

• The sample size of 90 is limited for robust statistical modeling or machine learning.
• Geographic scope is restricted to the Ate district in Lima, Peru, limiting generalizability.
• Data format is DTA (Stata), which may require specific software for access.
