dc.description | Aflatoxins are a topic of global interest due to their wide distribution, taking into account that they are secondary metabolites produced by fungi of the genus Aspergillus spp which, when found in factors that favor their development, can reach their toxic potential, having an affinity for contaminating grains and mainly cereals. The objective of this work is to know the main aflatoxin-producing fungi, as well as the toxic effects and their impact on public health. To do this, the collection of information that helps obtain detailed results based on the objectives set out in this work is analyzed through a bibliographic review, through scientific journals, articles, websites and virtual libraries. Therefore, the results determine that aflatoxins are persistent in the food chain, affecting the consumer indefinitely if they are destined for animal or human food, compromising the health of both parties in addition to causing low production rates in livestock such as economic losses, exposure to This substance continuously produces carcinogenic effects, with liver cancer being the most frequent, for this reason aflatoxins are declared the strongest natural toxin, it is important to highlight that one of the main reasons for this problem is the poor management carried out by agricultural producers when storing cereals under conditions of inadequate humidity and temperature, some of the regularizations carried out by the Codex Alimentarius help to mitigate this situation where the permissible limits indicate that for Aflatoxin B1 in peanuts and derived products it is 15 (µg/kg) in the case of feed this must be less than 10 ( µg/kg) while in milk and dairy products it is 0.5 (µg/kg) | es_ES |

dc.description.abstract | Las Aflatoxinas son un tema de interés a nivel global por su amplia distribución teniendo en cuenta que, son metabolitos secundarios elaborados por hongos del género Aspergillus spp los cuales al encontrarse en factores que favorezcan su desarrollo pueden alcanzar su potencial tóxico teniendo afinidad por contaminar granos y cereales principalmente. El objetivo de este trabajo es conocer los principales hongos productores de aflatoxinas, así como los efectos tóxicos y su impacto en la salud pública. Para ello, se analiza mediante una revisión bibliográfica la recopilación de información que ayude a la obtención de los resultados detallados a partir de los objetivos planteados en el presente trabajo, a través de revistas científicas, artículos, sitios web y bibliotecas virtuales. Por ende, los resultados determinan que las aflatoxinas son persistentes en la cadena alimentaria afectando al consumidor indefinidamente si estos son destinados a la alimentación animal o humana comprometiendo la salud de ambas partes además de ocasionar bajos índices productivos en ganadería como pérdidas económicas, la exposición a dicha sustancia de forma continua produce efectos cancerígenos siendo, el cáncer hepático el más frecuente, por tal motivo las aflatoxinas son declaradas como el toxico natural más fuerte, es importante destacar, que una de las principales razones de este problema es el mal manejo que realizan los productores agrícolas al almacenar cereales bajo condiciones de humedad y temperatura inadecuados, alguna de las regularizaciones realizadas por el Codex Alimentario ayudan a mitigar dicha situación donde los límites permisibles indican que para la Aflatoxina B1 en cacahuetes y productos derivados es de 15 (µg/kg) en el caso de los piensos esta debe ser menor a 10 (µg/kg) mientras que en la leche y productos lácteos es de 0.5 (µg/kg). | es_ES |
