Feeding chickens mealworms is illegal in some regions due to concerns about disease transmission and nutritional imbalances in poultry diets.
Many chicken owners are surprised to learn that feeding mealworms to poultry is illegal in certain regions. This restriction stems from food safety laws and disease prevention measures. Understanding these regulations helps keep your flock healthy and avoids potential fines.
Primary Reasons for the Mealworm Ban
The prohibition against feeding mealworms to chickens exists for several important reasons:
Disease Transmission Risks
Mealworms may carry pathogens that can infect poultry. The UK’s Animal and Plant Health Agency warns that insects raised for animal feed must meet strict biosecurity standards. Many commercially available mealworms don’t meet these requirements.
Research shows mealworms can harbor:
- Salmonella bacteria
- Avian influenza viruses
- Parasitic worms
Feed Safety Regulations
In the UK and EU, the Animal Feed Regulations prohibit certain protein sources in poultry feed. This includes processed animal proteins from insects unless specifically approved. The rules aim to prevent disease spread through the food chain.
Regional Variations in the Law
Regulations differ significantly by location:
| Region | Mealworm Status | Key Regulation |
|---|---|---|
| United Kingdom | Illegal for chickens | Animal Feed Regulations 2010 |
| European Union | Restricted | EC No 999/2001 |
| United States | Generally permitted | Varies by state |
Alternative Protein Sources
If you can’t feed mealworms, consider these safe options:
- Black soldier fly larvae (approved in many areas)
- Cooked eggs (excellent protein source)
- Plain yogurt (provides probiotics too)
- Peas and beans (plant-based proteins)

Understanding the Kitchen Scrap Ban
The prohibition extends beyond mealworms. Many regions ban feeding kitchen scraps to chickens due to:
Disease Control
The UK’s Animal By-Products Regulations prohibit feeding catering waste to farmed animals. This includes household food scraps that may contain meat or dairy products.
Food Chain Protection
These rules prevent potentially contaminated food from entering the animal feed system. The restrictions originated after disease outbreaks like foot-and-mouth disease were linked to improperly processed feed.
Practical Considerations for Chicken Owners
If you live in an area with these restrictions:
- Check local regulations before purchasing feed
- Store chicken feed separately from wild bird food
- Keep detailed records of feed sources
- Consider growing your own chicken treats

The Science Behind the Restrictions
Research from the Journal of Applied Poultry Research shows that improperly processed insect protein can:
- Alter gut microbiota in chickens
- Potentially transmit antibiotic-resistant bacteria
- Introduce foreign animal diseases
However, properly farmed and processed insect proteins show promise as sustainable feed alternatives when produced under controlled conditions.
Enforcement and Compliance
While enforcement varies, penalties for violations can include:
- Substantial fines (up to £5,000 in the UK)
- Quarantine of animals
- Destruction of contaminated feed
- Restrictions on selling eggs or meat
Always verify the legal status of any feed supplement in your area before offering it to your flock.
