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.
