Most Common Types of Food Poisoning
Getting a stomach “bug” (usually a bacteria or virus) from food is a horrible ordeal. Unfortunately, this is an experience that most people share. According to the FDA, 1 in 6 Americans will experience foodborne illness each year. Though food poisoning is generally mild and can be treated at home, some cases are more severe. Children, the elderly and those with compromised immune systems are at a higher risk of severe infections. However, some foodborne pathogens are life-threatening, even to healthy individuals.
Symptoms of food poisoning generally include nausea, abdominal cramps, vomiting, and diarrhea. The best protection against food poisoning is proper food handling practices. To avoid food contamination, make sure to wash your hands before handling foods and avoid leaving food at room temperature. Pregnant women, young children, the elderly and other people with weakened immune systems should be extra careful.
Food poisoning can take many different forms and come from many places. The term “food poisoning” is not entirely accurate. In most cases of foodborne illness, the culprit is a bacteria or virus. Though the toxins they produce cause many symptoms, the root cause of the illness is usually an infection. There are many different bacteria and viruses that can cause food poisoning. Mold, parasites, pesticides and natural toxins can also cause food poisoning. They vary in severity, symptoms, sources and how long they take to hit.
