Foodborne illnesses, often referred to as food poisoning, are conditions caused by consuming contaminated food or beverages. These illnesses are typically triggered by pathogenic bacteria, viruses, parasites, or toxins produced by these microorganisms. Symptoms can range from mild gastrointestinal distress, such as nausea, vomiting, and diarrhea, to severe, life-threatening neurological or systemic complications. Effective food preservation techniques are crucial in preventing the growth of these harmful agents and safeguarding public health.
