What is a common cause of about 95% of foodborne illnesses?

• A. Not washing hands
• B. Cooking meat to the wrong temperature
• C. Using contaminated water only
• D. Storing food in the fridge too long

Answer: (A)

Improper handwashing and poor personal hygiene are the most common causes of foodborne illness. Hands can carry bacteria from restroom use, raw foods, or contaminated surfaces, and when they touch food, utensils, or prep areas, pathogens can transfer directly to what people eat. Because this route affects nearly all foods and settings, improving hand hygiene—washing with soap and warm water for about 20 seconds and drying thoroughly—greatly reduces the risk across the board. That’s why this option is the best choice: it targets the most influential contamination pathway behind the majority of outbreaks. Other factors matter, but they don’t account for as much risk on their own. Contaminated water can spread illness, but outbreaks from water contamination aren’t the dominant driver of the total illness burden. Cooking meat to the wrong temperature is a risk, but proper hygiene plus correct cooking reduces that risk significantly. Storing food too long can lead to bacterial growth, yet many illnesses begin during handling and preparation, before storage becomes the main issue.
