Microbiological Quality of Agricultural Products

Revision sheet excerpt

Microbiological Quality of Agricultural Products (EU 3.4RO R3.13)

1. 📌 Essentials

  • Water quality standards require absence ofal coliforms and pathogens.
  • Microbial flora in water includes native aquatic, soil, and transient contaminants.
  • Biofilms are multilayered microbial communities embedded in EPS, resistant to disinfectants.
  • Surface hygiene involves cleaning, disinfection, and rinsing to control microbial contamination.
  • Airborne microbes include bacteria, spores, and fungi, transported via dust and aerosols.
  • Water originates from underground (aquifers) and surface sources, influencing composition.
  • Water pH is affected by geology; hardness depends on calcium and magnesium salts.
  • Microbial analysis involves filtration, incubation, and detection of indicator and pathogenic bacteria.
  • Recontamination can occur during transport, requiring continuous monitoring.
  • Surface biofilms impair cleaning efficacy and protect bacteria from disinfectants.
