The large and diverse group of microscopic foodborne yeasts and molds (fungi) includes several hundred species. The ability of these organisms to attack many foods is due in large part to their relatively versatile environmental requirements. WebYeast and molds (nonfilament and filament molds) may be found as part of the normal flora of a food product on inadequately sanitized equipment or as airborne contaminants. Shipping containers used for food samples should be dedicated to food samples and not be used for other types of environmental samples. To conduct this mini review, a comprehensive literature search on PubMed and Semantic Scholar to identify relevant studies on fungal spore levels in the air was performed.

In addition, if yeast is used in the poultry as prebiotic to suppress Salmonella, it might increase the level of yeast presence. The search strategy included the following keywords and their combinations: "spores/m3," "fungal structures/m3," "colony forming units/m3," "CFU/m3," and "FS/m3." Aspergillus, the most common opportunistic fungus, has over 300 species, with around 20 causing lethal infections in immunocompromised patients, predominantly by Aspergillus fumigatus, followed by other species such as Aspergillus flavus, Aspergillus nidulans, Aspergillus niger, and Aspergillus terreus. Results are reported to the submitting health unit as indicated on the requisition, when all analyses are completed. Asthma-related mortality rates also increase during airborne fungal spore peaks.18 All hospital-visiting asthma patients should be screened for exposure to fungal allergens and/or environmental exposure in the home or workplace to elevated mould spore levels, especially during thunderstorm asthma events.
