A lack of awareness among exotic bird owners regarding the quality of feed may contribute to adverse health outcomes, including toxicosis, systemic mycoses, and potentially neoplastic processes. Fungi of the Aspergillus genus are the most pathogenic to avian species, particularly due to their involvement in respiratory diseases such as aspergillosis, which affects the air sacs. This study aims to assess the presence of Aspergillus spp. in commercially available parrot feed (grain mixtures) available on the Polish pet market, considering different price categories. A total of 22 dry parrot food samples were analyzed using the PN-ISO 21527-2:2009 protocol. Aspergillus spp. colonies were isolated from 16 out of 22 samples (72.7%), indicating a high incidence of contamination. Although these results are preliminary, they highlight a microbiological risk associated with grain-based parrot feeds and underscore the need for stricter quality control and greater awareness among pet owners and manufacturers.
