    Area of Science:

    • Analytical Chemistry
    • Food Safety
    • Veterinary Pharmacology

    Background:

    • Sulfathiazole (ST) was previously used for treating American foulbrood disease in bees.
    • Regulatory restrictions exist on ST use in the US, necessitating reliable detection methods.
    • Honey contamination with veterinary drugs poses a risk to consumers and the apiculture industry.

    Purpose of the Study:

    • To develop a simple, inexpensive, and rapid screening method for sulfathiazole (ST) in honey.
    • To establish a sensitive detection limit for ST in honey samples.
    • To provide a tool for quality control and regulatory compliance in the honey industry.

    Main Methods:

    • A two-tube system employing alumina and an anion exchange resin (HSO4- form) was utilized.
    • Interfering pigments were removed by the alumina bed.
    • Sulfathiazole was trapped by the anion exchange resin, eluted, and detected using Bratton-Marshall reagents.

    Main Results:

    • The developed method can readily detect 0.1 ppm of sulfathiazole (ST) in honey.
    • An optional dye concentration step enhanced sensitivity, allowing detection of as little as 25 ppb ST.
    • The procedure is rapid, inexpensive, and suitable for screening small honey samples.

    Conclusions:

    • A cost-effective and efficient method for sulfathiazole screening in honey has been established.
    • The method's sensitivity is adequate for monitoring honey for ST contamination.
    • This technique supports efforts to ensure honey product safety and adherence to regulations.
