Frequently Asked Engineering Questions
Ph. Eur. 5.1.4 (inhalation use) enforces strict non-irradiated ceilings of TAMC <= 10^4 (10,000) CFU/g and TYMC <= 10^2 (100) CFU/g, whereas Ph. Eur. 5.1.8 Category B (herbal medicinal products) allows up to TAMC <= 10^5 (100,000) CFU/g and TYMC <= 10^4 (10,000) CFU/g provided pathogenic species (E. coli, Salmonella, and pathogenic Aspergillus) are completely absent.
Unlike benign epiphytic leaf yeasts, pathogenic Aspergillus species produce heat-stable mycotoxins (Aflatoxins B1/B2/G1/G2 and Ochratoxin A) and thermotolerant spores that survive vaporizer temperatures, causing severe pulmonary aspergillosis if inhaled.
