Food Poisoning vs. Food Spoilage: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on January 5, 2024
Food poisoning is an illness caused by consuming contaminated food, while food spoilage refers to the process of food becoming unfit for consumption due to microbial growth or chemical changes.

Key Differences

Food poisoning is an acute illness caused by eating food contaminated with bacteria, viruses, or toxins. In contrast, food spoilage is the process where food deteriorates to the point it is not edible due to bacteria, fungi, or chemical reactions.

Symptoms of food poisoning can include nausea, vomiting, and diarrhea, and can be severe. Food spoilage, on the other hand, is typically identified by a change in taste, smell, texture, or appearance, but does not always cause illness.

Food poisoning is primarily a health concern and can sometimes be life-threatening. Food spoilage, while it can lead to food poisoning, is more a matter of food quality, resulting in food waste.
