Presence of aflatoxin B1 in goat feed in goat milk production units of the Mexican Highlands
The presence of aflatoxins in silage and grains intended for feeding lactating ruminants entails a problem for animal health and milk safety. The objective of this study was to determine the aflatoxin B1 content in feed consumed by goats from four goat milk production units in the Mexican highlands (MHL). Samples (n= 47) of concentrates and 29 samples of silage from four goat milk production units in the Mexican Highlands (MHL) were analyzed by High Performance Liquid Chromatography (HPLC), using a reversed-phase column and fluorescence detection after the derivatization of aflatoxins. The results showed that 38.29 % and 31.02 % of the concentrate and silage samples, respectively, had AfB1 levels above the maximum permissible limit established by the European Union (EU) (0.05 µg/kg); while 29.78 % and 10.34 % for concentrates and silage, respectively, presented values higher than the 20 µg/kg proposed by the official Mexican standard. The results obtained corroborate the current problem of the presence of aflatoxins in the diet of lactating goats, as this toxin can be metabolized into aflatoxin M1 and affect the safety of milk and milk derivatives.

La presencia de aflatoxinas en el ensilaje y en granos que se destinan para la alimentación de los rumiantes en lactación representa un problema para la salud animal y la inocuidad de la leche. El objetivo del presente trabajo fue determinar el contenido de aflatoxina B1 en alimentos consumidos por cabras procedentes de cuatro unidades de producción de leche caprina del altiplano mexicano (APM). Un total de 47 muestras de concentrados y 29 muestras de ensilados procedentes de cuatro unidades de producción de leche caprina del Altiplano Mexicano (APM). Se analizaron 47 muestras de concentrados y 29 muestras de ensilados por Cromatografía de Líquidos de Alta Resolución (HPLC), empleando una columna de fase reversa y detección por fluorescencia previa derivatización de las aflatoxinas. Los resultados mostraron que el 38.29 % y 31.02 % de las muestras de concentrados y ensilados respectivamente presentaron niveles de AFB1 superiores al límite máximo permisible establecido por la Unión Europea (UE) (0.05 µg/kg); mientras el 29.78 % y 10.34 % para concentrados y ensilados respectivamente presentaron valores superiores a los 20 µg/kg propuesto por la norma oficial mexicana. Los resultados obtenidos corroboran la problemática actual de la presencia de aflatoxinas en la alimentación de las cabras lactantes, al poder metabolizarse esta toxina en aflatoxina M1 y afectar la inocuidad de la leche y derivados de encontrarse la misma.
