Perishable Foods and Food Spoilage (2024)

FAQs

What are perishable foods spoilage? ›

Perishable foods are those likely to spoil, decay or become unsafe to consume if not kept refrigerated at 40 °F or below, or frozen at 0 °F or below. Examples of foods that must be kept refrigerated for safety include meat, poultry, fish, dairy products, and all cooked leftovers. Refrigeration slows bacterial growth.

Perishable (goes off quick) Semi-perishable (goes off but last longer than perishable) Non-perishable (doesn't go off) Examples of food: Perishable. Perishable: Dairy products, fresh meat, fish, poultry, fruits, veg and sliced meat.

Food spoilage may be defined as a process or change which renders a product undesirable or unacceptable for consumption. This complex ecological phenomenon is the outcome of the biochemical activity of microbial chemical processes which will eventually dominate according to the prevailing ecological determinants.

Common signs of spoilage

Fruits and vegetables: Signs of spoilage on these foods include bad smells, soft or mushy texture, and mould. Seafood and meats: Spoiled seafood and meats often exhibit discolouration, slime and a foul odour.

A food is called “perishable” compared to non-perishable because they are the foods that go off fastest. Generally speaking, if it isn't canned, cured, salted, dried, or otherwise preserved, the moisture and the ambient heat make it a good environment for harmful organisms.

Highly perishable foods are those that have been harvested or slaughtered and are utilized with little or no further processing to prevent bacterial spoilage. This category includes, but is not limited to, the following fresh foods: raw vegetables, raw fruits, raw milk, fish, poultry, and red meats.

Foods spoil due to the growth of microorgan- isms (bacteria, yeasts, and molds) and/or the activity of enzymes naturally present in the food. The growth of microorganisms and the activity of enzymes are influenced by moisture, temperature, and presence of oxygen.

Some signs of meat, seafood and poultry spoilage include slime, discolouring and a bad smell. The most common signs of spoilage on dairy products include green or black mould, a strong smell or curdling.
