 Mycotoxins semiannual survey of mycotoxin in feed in 2022 Taiwan
In 2022 mycotoxins semiannual survey, Life Rainbow Biotech randomly collected 181 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.

Results:
181 feed samples collected, and 92% were contaminated with DON and 80% contaminated with Aflatoxins (table 1). The maximum concentrations of Aflatoxins, Zearalenone, Fumonisins and DON 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 181 samples, 33 samples from corn meal were analyzed that observed feed were contaminated 85% of DON (table 2).

Of 27 samples of nursery feed collected, and analyzed that feed sample were contaminated with 96% DON and 81% contaminated with Aflatoxins (table 3).

The occurrence of mycotoxin in pregnant diet also analyzed and founded that Aflatoxins and DON were most prevalent mycotoxins in pregnant diet, detected in 90% and 94% of samples respectively. (table 4).

Conclusion:
In 2022, the most prevalent mycotoxin exam in the feed samples in Taiwan was Aflatoxins and DON, 80% and 92% respectively. DON increased from 81% to 92% in the first and second half of the year. 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 17 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.
