Flies on Food: Is It Safe to Eat?

A fly lands on your plate. Should you eat it or throw it away?

The short answer

Because flies can carry germs, food a fly has landed on for a while, especially moist, cooked or ready-to-eat food, is best discarded, particularly for children and vulnerable people. Dry packaged foods that were only briefly touched are lower risk. Prevent the problem with covers, screens, prompt serving and clean surfaces. This is general advice and not medical advice.

Be cautious with

• Moist, cooked food left uncovered.
• Food where flies have been feeding or laying eggs.
• Food for infants and the elderly.

Lower-risk situations

• Food that is hot, freshly served and covered quickly.
• Sealed packaged goods.

Prevention

1. Use food covers and lidded containers.
2. Serve food promptly and refrigerate leftovers.
3. Fit screens and keep bins covered.
4. Control flies at the source.

When to call a professional

If the problem is widespread, keeps returning or you are unsure what you are dealing with, a professional inspection will save time and avoid wasted effort.
