Which condition indicates spoilage in food?

The presence of a slimy texture on food is a clear indication of spoilage. This sliminess often results from the growth of bacteria or mold, which can occur due to improper storage, temperature fluctuations, or simply the passage of time. When food becomes slimy, it typically means that it has deteriorated to a point where it is no longer safe to consume. This is especially common in perishable items such as meats, fish, and certain vegetables.

Other options are related to food storage and freshness. For instance, food being cold is generally a sign of proper refrigeration, which helps preserve it and prevent spoilage. Wrapping food tightly is a method used to keep it fresh by limiting exposure to air and contaminants, which can help slow down spoilage. Newly packaged food is often a sign of freshness, as it has been processed or packaged recently, indicating that it should still be safe to eat, assuming proper handling has been maintained throughout its distribution.
