Is it legal to feed food waste to my animals?
Rules differ by species, by the type of waste and by state. Pigs are the most tightly regulated. In many places, feeding food scraps that contain or have touched meat to pigs is restricted or prohibited because of the risk of spreading serious animal diseases.
Ask your state veterinarian or state agriculture department what applies to your animals and your food source. Ask specifically about pigs, poultry, and any waste from restaurants, bakeries or grocery stores, since these are often treated differently from your own vegetable trimmings.
Federal rules about feeding certain waste to pigs exist because of past disease outbreaks, and states add their own requirements. Your state veterinarian is the person to ask, and an honest question is welcome.
What are the main safety risks?
Food waste can carry disease organisms, spoiled or moldy material, and items that are toxic to animals. Contamination by plastic, string, metal or packaging is also common and can cause serious injury.
Animals can get sick from food that looks fine to you. Because disease reporting and biosecurity rules vary, your state veterinarian and extension service are the right place to get current guidance.
Even kitchen scraps that seem harmless can carry bacteria. Keep scraps cool and fresh, store them in closed containers away from pests, and clean buckets daily.
- Spread of animal disease
- Mold and spoiled food
- Toxic items such as certain plants and foods
- Packaging and foreign objects
Which scraps are usually considered lower risk?
Plain vegetable and fruit trimmings from your own kitchen are often considered lower risk for some species, if they are fresh and free of anything harmful. Even so, certain items are dangerous to certain animals, and what is safe for one species may harm another.
Check a species-specific list from your veterinarian or extension office before feeding anything new. Introduce changes slowly and watch the animals.
Chickens, goats and other species each have their own sensitive points. Some common foods are toxic to one species and fine for another, which is why a single list for all animals is unreliable. A small trial is a sensible way to learn. Offer a tiny amount of one new item, wait a day, and watch for changes in manure and behavior before offering more. Never switch several things at once.
What should I never feed?
Do not feed moldy, rotten or rancid food. Avoid anything that has been in contact with meat if you keep pigs or if your local rules restrict it. Keep out foods that your veterinarian says are harmful to your species, and never feed anything with packaging attached.
Never feed food from someone else's kitchen or from a business without first asking about the rules and the source. If you are unsure, do not feed it.
Bakery and restaurant waste may include meat, dairy, salt, sugar and additives, and it can be hard to know what is in it. Many places restrict feeding it, so ask first.
How does food waste affect nutrition?
Scraps are not a balanced diet. Animals still need a complete ration suited to their species, age and purpose, and too many treats can crowd out the feed they need. Some animals are prone to digestive trouble when diet changes suddenly.
Work with your veterinarian or an extension livestock specialist to decide how scraps fit into the overall ration. Keep records of what you feed.
If you are feeding scraps to save money, count the real costs: your time, storage, the risk of illness and veterinary bills, in addition to the feed you may replace.
- Count your time and storage needs
- Count the risk of illness
- Compare with the cost of ordinary feed
What are the signs something is wrong?
Watch for loss of appetite, diarrhea, bloating, lethargy, drooling, trouble breathing or any sudden change in behavior. Call your veterinarian promptly if you see these signs.
If several animals fall ill at once, or if you suspect a reportable disease, contact your veterinarian and your state veterinarian. Isolate sick animals as advised and do not move animals off the farm until you have guidance.
Keep a written record of what you feed, in case you need to give your veterinarian a history. Clear notes can speed up a diagnosis.
- Appetite loss or sudden pickiness
- Loose stool, bloat or drooling
- Dullness or standing apart from the group
Key takeaways
- Rules on feeding food waste, especially to pigs, vary by state.
- Never feed moldy, spoiled or packaged food, or anything toxic to the species.
- Scraps are not a complete diet and should fit a balanced ration.
- Call your veterinarian quickly if animals show signs of illness.
