Storage mites, especially several species in the families Acaridae, Glycyphagidae, and Chortoglyphidae are commonly found in farming and occupational environments. They are a source of clinically important allergens, and may also have a significant impact on forensic analyses. They may be of use in forensic situations, particularly as allergenic taxa, in relation to workers who are occupationally exposed to mites. Additionally, because many of them are present through all stages of vertebrate decomposition, they may provide valuable information as indicators of time and circumstances of death. This study aimed to investigate the possible occurrence and abundance of allergenic mites in farm buildings, as well as to examine and analyse collected material samples in relation to forensic medicine. A total of 58 samples from 15 farms in the Żywiecki district (Silesian Province, Poland) were examined as potential sources of allergenic mites in farm buildings with a special reference to forensic acarology. Mites were found in all the examined samples. A total of 4,473 specimens were isolated and 22 mite species were identified. Most of them were found in barns and pigsties. The species composition of the acarofauna was varied across the particular types of farm buildings examined. Generally, the dominant species were representatives of families Acaridae and Glycyphagidae (Astigmatina). This knowledge may be useful in a variety of cases or situations in the field of forensic medicine.
