Detailed explanation-1: -Bacteria enjoy foods that are neutral to slightly acidic. They will not grow in highly acidic foods like lemons and vinegars, but will grow well in vegetables, meat and some fruits. Temperature needs to be considered for bacterial growth.
Detailed explanation-2: -Bacteria are generally neutrophiles. They grow best at neutral pH close to 7.0. Acidophiles grow optimally at a pH near 3.0.
Detailed explanation-3: -The lactic acid bacteria are exceptions; they can grow in high acid foods and actually produce acid to give us sour milk, pickles, fermented meats, and similar products.
Detailed explanation-4: -Intrinsic properties of meat, such as pH and moisture can promote microbial growth, whereas temperature is an extrinsic factor. Fresh meat has a high water content that is favorable for the growth of microorganisms. It also generally contains bacteria, including those that can cause diseases.
