Definition
Mycotoxicosis from Fusarium toxins is a condition in dogs caused by ingestionIngestion refers to the intake of substances through the mouth and their delivery to the digestive tract. In dogs and cats, the ingestion of toxic substances, foreign objects, or incompatible foods can lead to health problems. of mold toxins produced by Fusarium species. These toxins can occur in various foods and feeds and lead to a range of health problems, from gastrointestinalGastrointestinal refers to the gastrointestinal tract, a system that extends from the oral cavity to the anus and is responsible for the digestion of food and the absorption of nutrients. disorders to severe systemic diseases.

Causes
Fusarium species are widespread molds found in the environment, particularly in agricultural products such as grains, corn, and feed. Under moist and warm conditions, these fungi can thrive and produce mycotoxins.
The main mycotoxins produced by Fusarium that are harmful to dogs include deoxynivalenol (DON), also known as vomitoxin, zearalenone, and fumonisins. These toxins can occur in contaminatedContaminated describes something that has been polluted by harmful microorganisms, chemicals, or other dangerous substances. In veterinary medicine, this can affect food, water, toys, or the environment. foods and enter the dog’s body through the food chain.
Sensitivity to these toxins can vary from dog to dog, depending on factors such as the dog’s size, the amount and duration of intake, and the animal’s overall health status. Puppies and older dogs in particular may be more susceptible to the toxicToxic means "poisonous" and refers to substances that can have harmful effects on the body, including damage to organs, cells, or disruption of metabolic processes. effects.
