Mycotoxins are a genuine threat to poultry production due to their unpredictable presence, which makes them difficult to detect. Mycotoxin is a toxin which is produced by molds. Sampling and Testing for Mycotoxins The risk of mycotoxin development may increase in crops that have been flooded and covered in silt. However, as stated previously, it is uncommon for most of the corn producing regions in the United States to have adverse weather and climatic conditions that lead to mycotoxin production in corn. In some of the sickest mold patients, if the mycotoxins are sequestered inside the cells, the level of mycotoxins in the urine may be very low and thus the test results may be negative. Acute and chronic exposure to mycotoxin contaminated feed can cause deleterious effects on the performance and wellbeing of the animals and leads to economic losses. However, in a correctly functioning rumen this mycotoxin is rapidly degraded so is assumed to be a lesser threat to ruminants. Mycotoxins occur in many varieties of food and feed.
