Final answer:
The correct statement regarding microbiology laboratory practices is that personal protective equipment must be worn at all times for safety and prevention of culture contamination.
Step-by-step explanation:
The true statement about the microbiology laboratory is that personal protective equipment should be worn at all times. This is to ensure the safety of lab personnel and the prevention of contamination of microbial cultures. Food cannot be stored in laboratory refrigerators, even if kept separate from lab specimens, to prevent contamination and maintain a sterile environment. Aerosol pathogens may indeed be handled in a microbiology laboratory, but under strict safety protocols. Quality control is absolutely necessary in a microbiology lab to ensure the accuracy and reliability of experimental results. Aseptic techniques and the use of personal protective equipment are central aspects of maintaining biosafety in any microbiology laboratory setting.
