10/10/2014: The impact of fumonisin on pig health

Fumonisin contamination of the pig diet is most commonly derived from corn contaminated with Fusarium verticillioides and Fusarium proliferatum. 

Brand new results from the BIOMIN Mycotoxin Survey 2014 (January – September) confirm that fumonisins are globally most common in corn, reports the blogspot Origin Matters-Mysotoxins.

worldwide and in selected areas (analyzed between January and September 2014)

Out of 512 corn samples 82% contained up to 130 246 ppb (corn sampled in Malaysia) of fumonisins. The average fumonisin contamination of positive corn samples was 2 280ppb. Similar to other fusariotoxins, occurrence of fumonisins is ubiquitous and not limited to a specific climate (compare figure 1). In the biggest corn producing countries such as Brazil, Argentina and USA, the contamination of corn with fumonisins was up to 100% with an average contamination of 3 297 ppb and a maximum contamination of 44 752 ppb (Brazil).

This state of the art technique developed at the hot spot for mycotoxin investigation the IFA-Tulln based in Austria, enables the detection of more than 380 metabolites in one go. This unique method not only includes the most commonly found mycotoxins but also allows the detection of other less known metabolites and provides the full picture of toxic load in the sample.

Fumonisins exert their main toxic effects by blocking ceramide synthase in the sphingolipid metabolism leading to accumulation of free sphinganine and to a lesser extent sphingosine. As a consequence, the production of complex sphingolipids - necessary components of nerves, muscles and also membranes is interrupted.
