Mycotoxins are secondary metabolites of fungi that can contaminate animal feeds at all stages of food production chain. Consumption of feed contaminated with mycotoxins may result in immunosuppresion, which represent a factor predisposing livestock to infectious diseases. From the epidemiological point of view, it is important to note that mycotoxins may cause breakdown of active immunity and occurence of disease even in properly vaccinated animals. The aim of the paper was to evaluate the influence of mycotoxins on the health status of piglets. The material for this research included the samples from five swine farms, where health disorders in suckling and weaned piglets were detected. Depending on the specificity of each evaluated case and available material, the applied research methods included: epidemiological and clinical evaluation, pathomorphological examination, standard laboratory testing for detection the precence of aerobic and anaerobic bacteria, virological testing and microbiological feed testing, in order to examine the presence of fungi and mycotoxins by the method of thin layer chromatography. In our research the persistant presence of various infections, which react poorly or do not react on the applied antimicrobial therapy was discovered. The presence of mycotoxin in feed can be directly connected to the detected health disturbances in piglets on the examined swine farms (vulvovaginitis, pneumonia, gastroenteritis).
