China and South Asia show highest mycotoxin risk in global feed survey

Mycotoxin contamination in animal feed was highest in China and South Asia during the first quarter of 2025. This is the outcome of DSM-Firmenich’s global survey, analysing 6,000 samples from 70 countries.

Ursula Hofstetter, Head of Mycotoxin Risk Management at DSM-Firmenich, said the findings showed the need for effective management. “Mycotoxins remain a serious and evolving threat to animal health, feed safety and food security. With changing climate and agricultural practices, understanding global trends is key. These findings again reinforce the urgent need for effective mycotoxin management to protect animal welfare and ensure the sustainability of feed and protein production.”

Levels for each mycotoxin in each region

China and Taiwan recorded the joint highest risk level of 94% with FUM (99%), DON (87%) and ZEN (67%) above the risk threshold. This was shared with South Asia, where Afla (87%), OTA (70%) and FUM (66%) were the 3 highest prevalence mycotoxins.

They were followed by:

Central America (85%) – ZEN (92%), FUM (85%) and DON (75%)

Middle East and North Africa (82%) – FUM (89%), DON (88%) and ZEN (83%)

East Asia (81%) – FUM (100%), DON (80%) and ZEN (41%)

North America (81%) – ZEN (81%), DON (75%) and FUM (51%)

Southern Europe (79%) – FUM (80%), ZEN (73%) and DON (65%)

South America (77%) – FUM (71%), ZEN (70%) and DON (48%)

Central Europe (74%) – FUM (80%), ZEN (73%) and DON (65%)

South East Asia (71%) – FUM (86%), DON (61%) and Afla (54%)

Sub-Saharan Africa (56%) – DON (93%), ZEN (55%) and FUM (53%)

South Africa (41%) – DON (84%), FUM (55%) and ZEN (50%)

Northern Europe (38%) – DON (71%), ZEN (48%) and FUM (28%)

Eastern Europe (23%) – DON (61%), ZEN (57%) and T2 (49%)

Oceania (16%) – FUM (82%), DON (27%) and ZEN (24%)

76% of all samples contained more than 1 mycotoxin with just 6% of showing no mycotoxins detected.

Risk levels posed to each species

Levels of mycotoxins taken in the 1,087 samples covering China and Asia saw consistent rises in contaminated samples across the mycotoxins studied (ie FUM 79%, compared to 68% in the same period last year). The greatest level of concerns were the levels of FUM for the shellfish sector and Afla for ruminants and pigs.

In North America, the extreme risks were to all species from DON levels, with one sample recording 11785ppb.
