Three factors that contribute to bacteria growth, which cause meat to spoil, are heat, dirt, and__________

Bacteria thrive in environments that provide them with the necessary conditions for growth, and moisture is one of the critical factors that contribute to this process. When moisture is present, it creates an ideal environment for bacteria to multiply. In the case of meat, if it is not stored properly—particularly if it is kept in humid conditions or exposed to water—it can lead to rapid bacterial growth, resulting in spoilage.

In addition to moisture, heat creates a favorable environment for bacteria, as many types of bacteria grow well at warmer temperatures. Dirt can also introduce bacteria to the meat. However, without adequate moisture, the bacteria’s ability to thrive diminishes significantly. Therefore, moisture is essential to the spoilage process, making it a key factor alongside heat and dirt.
