Mycotoxins semiannual survey of mycotoxin in feed in 2021 Taiwan

In 2021 mycotoxins semiannual survey, Life Rainbow Biotech randomly collected 163 feed samples of raw materials and feed mills in farms and analyzed. The samples were tested for aflatoxins (B1, B2, G1, and G2), zearalenone, fumonisins (B1, B2, and B3) and deoxynivalenol (DON) by the ELISA Mycotoxin analysis kit.

163 feed samples collected, and 74.8% were contaminated with Zearalenone and 71.8% contaminated with Aflatoxins (table 1). The maximum concentrations of Zearalenone and Fumonisins were over the limit of quantification in this survey.

Data on corn meal, nursery, and pregnant diet were conducted to give the prevalence of mycotoxins. Out of total 163 samples, 32 samples from corn meal were analyzed that observed feed were contaminated 75% of deoxynivalenol, whereas the maximum of positive of fumonisins is exceeds the detection limit (table 2).

Of 28 samples of nursery feed collected, and analyzed that feed sample were contaminated with 89.3% Zearalenone (table 3).

The occurrence of mycotoxin in pregnant diet also analyzed and founded that Aflatoxins and Zearalenone were most prevalent mycotoxins in pregnant diet, detected in 77.4% and 71% of samples respectively. (table 4).

In 2021, the most prevalent mycotoxin examined in the feed samples in Taiwan was Zearalenone and Aflatoxins, 74.8% and 71.8% respectively.

To prevent mycotoxins' appearance in grains and cereals, the effective method is to avoid mold infection and populations' formation during grain growth to ensure that the harvested grains are clean and healthy. If the harvested cereals are contaminated, it is necessary to regulate the storage conditions to stop the expanded contamination scope. Mycotoxin contaminated feedstuffs will raise the risk to impact animal production and economic profit. According to the reginal survey, feed manufacturers and animal producers can be aware of the occurrence of mycotoxins and implemented actions into mycotoxin management.

Life Rainbow Biotech has researched mycotoxins for 15 years and developed an enzyme-type mycotoxin degrading product: Toxi-Free PLUS®. Toxi-Free PLUS® has three different special activity enzymes to degrading various types of mycotoxins and reducing the toxins' effect—reducing animal hazards. Adding Toxi-FreePLUS® to the feed use as a daily care product, can protect the farmed animals and reduce the damage caused by the mycotoxin, and make the animal live more comfortably and increase the farmer's profits.
