VICAM’s DON-V strip tests answer one of today’s toughest food safety challenges with a new user-friendly lateralflow DON test that delivers accurate quantitative results in a matter of minutes. DON is a toxic byproduct of several Fusarium mold species that commonly infect wheat, corn, barley, and other grains. Nicknamed vomitoxin for its severe effects on the gastrointestinal system, DON may also cause reduced feed intake, poor weight gain, and immunosuppression in susceptible livestock species, even at low concentrations (1 to 3 ppm). Concerns about acute DON toxicity, as well as the risks of chronic exposure, in animals and humans continue to fuel surveillance of grain crops worldwide.
DON is often present with other mycotoxins and has been isolated from grains and feeds throughout the world at levels as high as 92 ppm. Today, many customers require DON levels to be less than 2.0 ppm for animal feed and 1.0 ppm for commodities destined for human consumption.
The United States FDA has instituted advisory levels of 1 ppm for wheat products for human consumption, 5 ppm for grain products for most animal feeds and 10 ppm for grain products for cattle feed. T he European Community has regulations for DON levels that range from less than 0.2 ppm in processed cereal-based foods for infants and young children to less than 1.75 ppm for unprocessed wheat. In Asia, regulations for DON range from 0.2 to 4 ppm.
DON-V test strips utilize the proven sensitivity and selectivity of VICAM’s monoclonal antibodies to accurately detect and measure total DON in grain and feed at levels as low as 0.20 ppm. T he single-dilution sample preparation procedure saves time and materials, and the test takes less than 5 minutes* to complete. Digital readings are clearly displayed on the screen of the Vertu™ Lateral Flow Reader, eliminating any guesswork about the results.
