    Summary

    A study found no ochratoxin contamination in 41 grain and feed samples. The Nesheim et al. (1973) method is recommended for ochratoxin testing in Czechoslovakia.

    Area of Science:

    • Food safety analysis
    • Mycotoxin detection
    • Analytical chemistry

    Context:

    • Ochratoxin is a significant mycotoxin found in grains and animal feed.
    • Accurate detection methods are crucial for ensuring food and feed safety.
    • Previous analytical procedures were evaluated for ochratoxin detection efficacy.

    Purpose:

    • To evaluate the Nesheim et al. (1973) analytical method for detecting ochratoxin in grains and feed mixtures.
    • To determine the prevalence of ochratoxin in feed and grain samples under specific storage conditions.

    Summary:

    • The Nesheim et al. (1973) method was selected for its suitability in detecting ochratoxin.
    • Forty-one diverse samples (barley, corn, wheat, oats, feed mixtures, straw) were analyzed.
    • No ochratoxin was detected in any samples, even those visually free from mold and stored safely.

    Impact:

    • The study validates the Nesheim et al. (1973) method for routine ochratoxin analysis in Czechoslovakia.
    • Findings suggest a low risk of ochratoxin contamination in the analyzed feed and grain under optimal conditions.
    • Provides a reliable method for regulatory bodies and agricultural enterprises to ensure feed safety.
