The Hidden Dangers of Insects in Canned Drinks

In cooperation with Dr. Susan Harper, Entomologist & Public Health Specialist.

Many people enjoy sipping from a can, unaware that insects could pose serious health risks—especially for children. Research shows that flies, wasps, and other insects are more than just a nuisance; they can contaminate your drink, causing illness or even injury.

How Do Insects Enter Cans?

Insects are attracted to sweet beverages and can crawl into open cans undetected. Flies, for example, may lay eggs in sugary liquids, and wasps often slip inside while searching for food.

The Health Risks Involved

Insect contamination poses serious health hazards, including:

• Foodborne Illness: Flies carry pathogens such as Salmonella and E. coli.
• Stings and Allergic Reactions: Wasps trapped inside cans can sting the mouth or throat, a severe risk for children and those with allergies.
• Bacterial Infections: Insect contact increases the chance of harmful bacteria entering your body.

A Greater Risk for Children

Children are at higher risk because they often drink quickly without checking the can. Their smaller airways also make wasp stings inside the mouth or throat particularly dangerous.

How to Stay Safe

• Always inspect your can before drinking.
• Use a can cover or drinking attachment to prevent insects from entering.
• Pour the beverage into a glass to ensure no hidden pests.

Conclusion

While canned drinks are convenient, the risk of insect contamination should not be ignored. Simple precautions, such as using protective covers, can prevent accidents and protect your health—especially for children. Stay safe and sip smarter.
