Nebraska Grain & Feed Tentatively Planning a “Managing Mycotoxins” Workshop for May, 2010

The National Grain and Feed Association (NGFA) has learned that the U.S. Food and Drug Administration (FDA) is scheduled to finalize a plan as early as March 26 under which it will sample grain and grain products – starting as early as the week of March 29 – for the presence of the mycotoxin deoxynivalenol (vomitoxin).  Meanwhile, in order to prepare our members for possible grain quality issues involving mycotoxins, the Nebraska Grain and Feed Association (NGF) is tentatively planning to conduct a “Managing Mycotoxins” workshop for sometime in May, 2010.  Please watch for future details.

The plan is designed to provide FDA with better information about the potential prevalence in suspected geographical areas of vomitoxin in raw wheat, corn, barley and oats, as well as milled co-products, intended for both human and animal feed.  The agency’s plan will call for collecting approximately 200 total samples, equally split between:


  • human-grade milled wheat products (flour, germ and bran); and
  • feed-grade products, which will include samples of raw corn, wheat, barley and oats, as well as corn and wheat co-products.  FDA anticipates that it will complete testing of the samples by July.


The sampling of grains and grain co-products is in response to weather conditions that occurred in several parts of the country during the 2009 crop-growing season, which were cooler and wetter than normal. Such conditions are conducive to the development of the Fusarium fungi that produce vomitoxin, as well as such other mycotoxins as zearalenone and T-2.  It is the NGFA’s understanding that FDA’s sampling plan, which will be distributed to the agency’s district offices for execution once finalized, will be focused on the following 14 states in which such conditions were present in varying degrees: Kansas, Kentucky, Illinois, Indiana, Maryland, Michigan, Minnesota, Missouri, New York, North Carolina, Ohio, Pennsylvania, Tennessee and Virginia.

Under the regulatory framework adopted by FDA, the agency issued its most recent advisory levels for vomitoxin in September 1993. FDA advisory levels provide guidance to the industry concerning levels of a substance present in food or feed that are believed by the agency to provide an adequate margin of safety to protect human and animal health.  While FDA reserves the right to take regulatory enforcement action – including seizure of the product – on a case-by-case basis (particularly in egregious situations), enforcement is not the primary purpose of an advisory level.  Importantly, the NGFA is aware that the agency has begun a review of scientific studies on the health risk posed by vomitoxin to various animal species, particularly ruminants and poultry, to determine if somewhat higher levels may be fed safely.  Based upon its review of such scientific data, the agency will determine whether it is appropriate to revise the current advisory levels.  The NGFA is communicating closely with the agency during its review.  FDA’s current advisory levels for vomitoxin are indicated in the following table.


FDA's Current Advisory Levels for Vomitoxin Product and Intended Use Vomitoxin Level (parts per million)


  • Human food products 1 p.p.m.
  • For grain and grain byproducts destined for swine. (FDA advises that commodities 5 p.p.m. containing this level of vomitoxin not exceed 20 percent of the ration.)
  • For grain and grain byproducts destined for beef cattle and feedlot cattle older than four months, as well as for chickens.  (FDA 10 p.p.m. recommends that commodities containing this level of vomitoxin not exceed 50 percent of the ration for these species.)
  • For grain and grain byproducts destined for all other animal species. (FDA recommends that commodities containing this 5 p.p.m. level of vomitoxin not exceed 40 percent of the ration.)
