Survey for aflatoxin B1 in chicken eggs
Journal - Association of Official Analytical Chemists
|July 1, 1978
Summary
Aflatoxin B1 was detected in one liquid egg white sample in 1977. Shell eggs sold to consumers in the southeastern US were free of aflatoxin contamination during the study period.
Area of Science:
- Food safety analysis
- Mycotoxin detection in food products
Background:
- Aflatoxins are toxic secondary metabolites produced by certain molds.
- Egg products are a potential vehicle for mycotoxin contamination.
- Previous research indicated a need to assess aflatoxin levels in US egg supplies.
Purpose of the Study:
- To determine the prevalence and levels of aflatoxin B1 in egg products.
- To assess the safety of shell eggs for consumers in the southeastern United States.
Main Methods:
- Analysis of 112 egg product samples, including liquid egg white and shell eggs.
- Samples were collected from 35 establishments in the southern US during 1977.
- Aflatoxin B1 levels were quantified using established analytical methods.
Main Results:
- Aflatoxin B1 was identified in one liquid egg white sample at a concentration of 0.06 ng/g.
- No aflatoxin contamination was detected in 101 shell egg samples.
- Shell eggs were sourced from Alabama, Georgia, South Carolina, and North Carolina.
Conclusions:
- The risk of aflatoxin B1 contamination in commercially available shell eggs in the southeastern US was low in 1977.
- Liquid egg white may require specific monitoring for potential mycotoxin presence.
- Further surveillance of egg processing methods is warranted.
