The objetive was to determine the presence and levels of fumonisins in feed from confirmed cases of equine leukoencephalomalacia from the Municipality of Juchitlán (Jalisco State). The field study included the 13 main municipalities where one of the biggest equine population in Jalisco is concentrated. They have a similar feeding management practices and feed preservation. The analytical determinations were performed by competitive type immunoassay and high-resolution liquid chromatography. Contamination with fumonisins was detected in 100 % of analyzed samples; levels were from 0.23 to 19.18 mg/kg. There was a difference between localities (P<0.001); the highest concentration was observed in Ahualulco de Mercado (mean: 12.83 mg/kg) and the lowest concentration in Concepción de Buenos Aires (mean: 0.27 mg/kg). Of the total samples analyzed, 62 % exceeded the recommended limit for horses.
