It might not be possible to completely eliminate known mycotoxins from contaminated agricultural commodities
Mycotoxins are secondary metabolites of low molecular weight produced by a wide range of fungi. There are over 300 species of fungi that produce mycotoxins. Aflatoxins (AF), zearalenone (ZEN), ochratoxin A (OTA), fumonisin (FUM), trichothecenes such as deoxynivalenol (DON), and T-2 toxin are some of the mycotoxins that can significantly impact the health and productivity of livestock and poultry species. These toxins are found as natural contaminants in many feed ingredients of plant origin like cereals, seeds, fodder etc. Hence mycotoxins seem to be the most relevant with respect to feed contamination and have a significant economic impact in the animal industry. Fungi grow wherever temperatures and humidity are optimal, and unfortunately weather conditions at harvest time, and/or harvesting practices (such as leaving cut grains in the field before recovery) often promote contamination of cereals, grains and legumes with mycotoxins. There is a great deal of variability in mycotoxin contamination from place to place, and from year to year, depending on local weather and humidity at the time of harvest. With regional weather becoming more unstable and extreme due to climate change, mycotoxins diversity and contamination levels are only expected to rise in the future.
Agricultural commodities are now originating from all corners of the globe& spreading threat of mycotoxins through animal feeds produced worldwide. Minimizing the risk of mycotoxins from the field where crops are grown to animal feed and eventually food is a complex process that starts with prevention at the farm and requires a great deal of effort at every step in the food production chain (Jouany 2007). Consequently, it is assumed that it is not possible to completely eliminate more than 300 known mycotoxins from contaminated agricultural commodities. Customers have to take precautionary measures to eliminate mycotoxin risk.
Cargill World Mycotoxin Survey, 2019 consists mycotoxin results of2,82,277 commodity samples sourced from more than 55 countries. 170 ingredients covering entire gamut of ingredients used in poultry, cattle & swine have been chosen for analysis. All ingredients have been analyzed for 6 mycotoxins predominantly, which pose serious threat on poultry, cattle & swine species. All analysis has been done locally & compiled centrally in form of World Mycotoxin Survey.
