Fumonisins were the most recent mycotoxin found to affect humans and animals negatively. The most produced toxin for this group of fungi is fumonisin B1. [2] Studies have shown that it can cause diseases such as equine leukoencephalomalacia in horses, hydrothorax and porcine pulmonary edema in swine, and it can negatively affect the immune system.
Upon consumption, the toxin inhibits ribosomal protein, DNA and RNA synthesis, [22] [21] [23] mitochondrial functions [24] [25] [26] cell division [27] [28] while simultaneously activating a cellular stress response named ribotoxic stress response. [29] The trichothecene mycotoxins can be absorbed though topical, oral, and inhalational routes. [21]
A 2010 study in the Journal of Mycotoxin Research tested 26 commercial dog foods and found mycotoxins at concerning sub-lethal levels. It was determined that long-term exposure to low levels of confirmed mycotoxins could pose chronic health risks. [126]

T-2 mycotoxin is a trichothecene mycotoxin. It is a naturally occurring mold byproduct of Fusarium spp. fungus which is toxic to humans and other animals. The clinical condition it causes is alimentary toxic aleukia and a host of symptoms related to organs as diverse as the skin, airway, and stomach.
Mycotoxicology is the branch of mycology that focuses on analyzing and studying the toxins produced by fungi, known as mycotoxins. [1] In the food industry it is important to adopt measures that keep mycotoxin levels as low as practicable, especially those that are heat-stable.
There were outbreaks of dog food containing aflatoxin in North America in late 2005 and early 2006, [38] and again in late 2011. [39] Mycotoxins in animal fodder, particularly silage, can decrease the performance of farm animals and potentially kill them. [40] [4] Several mycotoxins reduce milk yield when ingested by dairy cattle. [40]
