What is the best means of inhibiting the growth of microorganisms in fresh meat?

The best means of inhibiting the growth of microorganisms in fresh meat is adequate refrigeration and cleanliness. Maintaining a proper refrigeration temperature (typically below 40°F or 4°C) slows down bacterial growth significantly, as most pathogenic and spoilage microorganisms multiply rapidly at warmer temperatures. Cleanliness is equally vital; it involves proper handling and sanitation practices that prevent cross-contamination and the introduction of pathogens to the meat.

While other methods, such as the use of chemical preservatives, topical hypochlorite solutions, or ultraviolet light, may have their places in food safety, they do not address the fundamental principles of temperature control and cleanliness that are essential for preserving the quality and safety of fresh meat over time. Chemical preservatives can have limitations on their own, and the effects of ultraviolet light may not penetrate effectively in all parts of the meat, particularly if it is not in a thin layer. Therefore, for effective inhibition of microbial growth, particularly in a practical and holistic sense, refrigeration combined with proper cleanliness is the most reliable approach.
