Updated May 25, 2021

It can be a challenge to ensure goat residents have healthy, happy lives after coming to a sanctuary, and there are many different aspects of care to consider each day. Unfortunately, toxic and poisonous hazards are sometimes overlooked in the hustle and bustle of operating a sanctuary. While minor exposure to many of these toxins are unlikely to cause serious problems, large amounts can cause severe health issues and sadly, even death. There are also some toxins that are highly dangerous even in small amounts.

In order to help ensure you never run into this problem, we have compiled this resource of common plants and other potentially toxic things that have been known to be a problem for goats.

Toxic Plants

This is not an exhaustive list. There may be particular plants that grow in your region that are not included on the list. Check with your region’s agricultural department to ensure you have a full picture of what could be problematic for goats in your area!

Ask About Activated Charcoal

While prevention is imperative when it comes to protecting your residents from toxins, in the event that they accidentally ingest something toxic, the administration of an activated charcoal product may help absorb the toxins. This is not a magic cure and may not be appropriate in all situations, but it can be helpful to have on hand. We suggest asking your veterinarian if there are specific products they recommend for the various species in your care so you can have them ready should you need them. In addition to seeking urgent medical care, if a resident ingests a toxin, ask your veterinarian if administration of activated charcoal is advised.

Plants That Are Toxic To Goats

We have built a list below of a number of plants known to be toxic in some way to sheep. If you’d like more information, Check out The Open Sanctuary Project’s Global Toxic Plant Database and filter Species Afflicted by goat in order to see a list of plants across the world that are toxic to sheep. Please note that, while comprehensive, this list may not contain every single plant toxic to goats!
Black Locust

Buckwheat
  • Animals with white skin are most severely affected.Image by Hans Braxmeier from Pixabay
  • Black skinned animals are not affected except for showing photophobia if the eyes are not pigmented. Initially the non pigmented skin becomes reddened, severely pruritic, swollen and painful.
  • Severe photosensitization results in serum exidation and necrosis of the skin, causing the skin to become dry, parchment-like and eventually sloughing.
  • Affected animals become very agitated when exposed to sunlight often desperately seeking shade under vehicles, buildings, trees etc. to avoid exposure to sunlight light.
  • Photophobia and tearing may be evident.

    Other Potential Goat Toxins

    Algae

    Blue-green algae, which is most often found in stagnant, slow-moving water when temperatures are high, can poison goats. Symptoms generally develop quite rapidly and may resemble an allergic reaction. Convulsions may occur, but more frequently the animal sinks to the ground, and dies without struggling. Smaller amounts of poison cause weakness and staggering, followed by recovery. In some instances, apparent recovery from an attack is followed in a few days or weeks by evidence of photosensitization. There may be inflammation of the muzzle, the skin of the ear, the udder, or other parts of the body. Jaundice is often seen, and constipation is a common symptom. Such cases usually recover under good care.

    Cantharidiasis (Blister Beetle Poisoning)

    Blister beetles contain cantharidin, a toxic substance that is used as a defense mechanism against predators. There are more than 200 different species, and they can be found from Mexico to Southern Canada, and from the east coast of the United States as far west as New Mexico. Cantharidin can severely injure or kill goats when even a small amount is ingested. Goats come into contact with cantharidin by ingesting alfalfa hay that has been infested by blister beetles. The oily substance can contaminate the hay even if the beetles were crushed into the feedstuff. Crushing or chemically eradicating the beetles does not diminish the toxin potency.

    Inspecting individual flakes of alfalfa hay before providing them to residents can help reduce the likelihood of poisoning. Dispose of any contaminated flakes, even if you have removed the beetle, as the toxin can still be left behind.  First-cutting hay is less likely to be contaminated than hay harvested later in the year, as the insects likely haven’t yet swarmed by then. Harvest alfalfa before it fully blooms to reduce the chances of beetle contamination. Hay is less likely to be contaminated by crushed beetles when harvested with a self-propelled mower or windrower. Crimping hay crushes the beetles into the hay.

    Goats that ingest a massive amount of toxin may show signs of severe shock, and unfortunately, die within hours. Symptoms of sublethal poisoning include depression, diarrhea, elevated temperatures, increased pulse and breathing rates, and dehydration. There is also frequent urination, especially after the first 24 hours. If cantharid poisoning is suspected, a veterinarian should be contacted immediately.

    If you suspect Blister Beetle Poisoning, contact your veterinarian immediately. If early veterinary care is provided, afflicted goats have a chance of recovery.

    Copper

    While copper is actually supplemented into the diets of many goats, it is possible for them to develop copper poisoning. Copper toxicity is a result of too much copper in the diet. Typically due to ingestion of something not intended for the goat such as chicken feed, cattle mineral, or pig mineral. A sign of copper toxicity is copper colored urine. The urine will also have a sweet smell. Goats are more likely to develop copper poisoning during times of intense stress such as during transport or in extreme weather. This is due to copper being released in the body under stressful conditions.

    Grain Overload (Acidosis, Grain Poisoning)

    Grain overload occurs when goats eat large amounts of grain, causing carbohydrates to be released in the rumen and ferment instead of being normally digested. Lactic acid is produced resulting in slowing of the gut, dehydrations, and sometimes, sadly, death. While wheat and barley are the most common causes of grain overload, lupins and oats can also be the culprit.

    Grain overload is most commonly seen where goats may be in a newly harvested pasture and spilled and unharvested grains remain, and when goats gain access to bags or cans of grains and pellets. If a goat isn’t accustomed to eating grain, a sudden switch to grains might cause grain overload as well.

    Signs of grain overload include:

    • depressed appearance
    • lying down
    • diarrhea
    • dehydration and thirst
    • bloating (of the left side of the abdomen)
    • staggery or tender gait and ‘sawhorse’ stance
    • death

    If you suspect a goat has grain overload, contact a veterinarian immediately.  Treatment depends on the severity of the condition. Following grain overload, the rumen lining takes up to six weeks to repair, and some animals may develop secondary infections that will require veterinary treatment.

    Hardware Disease

    Hardware Disease refers to the injuries that can result from any animal resident eating something they shouldn’t, especially pieces of human-made hardware like nails, screws, and staples. Hardware disease can have devastating effects on any resident. Check out our resource on Hardware Disease prevention here.

    Lead Toxicity

    Lead was once used in paints and pesticides, and can also be found from natural environmental sources. Even if you have never used any products containing lead, it may still be present in old barn or fence paint, or in the soil. Places where old machinery and leaded gas have been stored may also have caused contamination, as would old treated lumber and railroad ties. Goats may ingest the lead in the environment through the consumption of grass, clover, and dandelion or from chewing or licking on tainted surfaces.

    Having the soil tested at your sanctuary is an easy way to learn if the environment is safe for residents. You can check with a local environmental conservation service, or agricultural extension office to inquire about testing. It is usually a fairly quick and easy process. Prevent your residents from accessing buildings and fences with old paint, as they may chew or lick these objects and ingest lead.

    Goats with low levels of lead toxicity do not generally exhibit signs. In severe cases, you may see the following symptoms:

    • loss of appetite
    • weight loss
    • lethargy and weakness
    • incoordination
    • anemia
    • unusual manure consistency or diarrhea
    • respiratory distress or blindness

    Consult a veterinarian immediately if you suspect a goat has ingested lead or is beginning to show symptoms of lead poisoning.

    Mycotoxins

    Mycotoxins are a toxin produced by molds (fungi) that are harmful to many animals. Mycotoxins can affect goats through contaminated food or bedding. Moist, warm environments make a perfect recipe for mold reproduction. While goats are more resistant to the effects of mycotoxin than horses, they can still be affected. The type and amount of mycotoxin a goat digests affects whether the health issues are immediate and short-lived or may become chronic issues. Pregnant goats and young goats are more susceptible. Some general signs of poisoning include:

    • appetite loss
    • weight loss
    • respiratory issues
    • increased susceptibility to infectious diseases (poor immune function)
    • poor growth rate

    Prevention is key in avoiding serious health issues. Luckily, there are a number of steps you can take to help ensure resident goats do not suffer the ill effects of mycotoxin poisoning:

    • Be sure to keep food, grain, and hay storage areas clean, dry, and cool
    • Try to keep food storage areas protected from mice and rats and other wildlife, as they can chew holes in food bags, increasing the likelihood of grain being exposed to damp conditions
    • Always feed the oldest sources of food first. Try to use up open food bags within a few weeks after opening in the winter and in even less time in the summer
    • Clean any storage bins or cans thoroughly to remove old grain that may get stuck in cracks and crevices
    • Check with your food manufacturer or supplier to see if they regularly test for the presence of mycotoxins in grains before mixing food. If they do not, avoid using them and find another supplier

    If you are concerned about the possibility of mycotoxin contamination, have your food stores tested. This could be especially important if you have a goat that shows initial signs of mycotoxin exposure.

    Pesticides, Herbicides, And Rodenticides

    It may not come as a surprise that herbicides and rodenticides can cause toxicosis in goats if ingested. If goats ingest plants that have been sprayed with phenoxy acid herbicides, they can become ill or even die. For this reason, it is imperative that goats are not given treated plants or are allowed access to pastures that have been treated with herbicides.

    While rats and mice can pose challenges for sanctuaries, it is important to respect them and use compassionate mitigation practices. Many rodenticides are anticoagulants and act by preventing the blood to clot. These products may be appealing to goats as well, and they may attempt to lick or eat them if discovered. For this reason, it is imperative that they do not come into contact with these poisons. There are many new and innovative ways to address rodent populations that are more effective and compassionate.

    Pesticides may affect the nervous system in goats and can be fatal if not treated with the antidote. Early treatment is critical. If you suspect a goats may have ingested any of the poisons above, contact your veterinarian immediately. Blood tests may confirm poisoning.

    Selenium

    Selenium is a highly toxic element when taken in quantities larger than what is needed for normal metabolism. In most plants, the level of selenium is related to levels in the soil. The symptoms of selenium poisoning are: dullness, stiffness of joints, lameness, loss of hair from their body or tail, and hoof deformities. The acute form of poisoning is often called “blind staggers”.

    Snakebites

    Venomous snakebites are not common, but when they occur, should be treated seriously and immediately. The most common location for a goat to be bitten are on the nose or leg. It is possible for a snake to bite several times, so if you notice a snakebite, look for others. Snake venom varies by species, and the severity of a bite can also be influenced by size, age, and the number of bites. Most venoms can impair blood clotting and damage the heart, while some others contain neurotoxins. Signs of a snakebite may include:

    • Pain
    • Swelling at the bite site
    • One or more puncture wounds
    • Sloughing of tissues near the bite site
    • Cardiac arrhythmias
    • Impaired ability for their blood to clot
    • Shock
    • Collapse
    • Paralysis
    • Death

    Seek veterinary care immediately if a goat is bitten by a venomous snake. Do NOT try to suck the venom out or place a tourniquet. Keep the goat calm while seeking immediate veterinary care. Depending on the severity of the bit, treatments may include antivenin, pain medications, fluid therapy, wound treatment, tetanus vaccination, and antibiotics. Check out our Compassionate Wildlife Practices At Your Animal Sanctuary for some tips on how to dissuade snakes from your property.

    Wood Stains And Paints

    Some wood stains and paints can be toxic to goats. Goats may try to chew on painted surfaces and can become ill if the stain or paint is toxic. Try and purchase paints and stains that are specially made for barns and fencing and listed as animal or “livestock” friendly.

    Foods That You Should Not Feed To Goats

    Use Caution
    You may have experience successfully feeding one of the foods on this list to your goat residents. For this list, we erred on the side of caution, including foods that are well known to be toxic to others that some have had success in feeding to residents but still are known to contain potential toxins. Some foods are only problematic in large doses or in their raw state or only their seeds or roots. Some are very toxic while others have milder effects on the individual. There is a lot of information on the internet, much of it conflicting or lacking the necessary detail to prove especially helpful. Having a better understanding of which parts or in what state some foods are toxic can help you make safe choices for your residents. Always use caution and speak with your veterinarian.

    In addition to the above, these foods should be avoided:

    • Animal products of any kind
    • Avocado (Any part of the plant (fruit, leaves, stems, bark, and seeds) can be toxic to goats. The toxic element in avocado is persin)
    • Brassicas -Broccoli, cauliflower, cabbage, brussel sprouts. Turnips and kale are also in this family. Turnips have some specific toxicity issues concerning thyroid production. (Use caution. Don’t feed large amounts. Avoid seeds and roots.)
    • Celery (Use caution. Celery contains furocoumarins which can cause photosensitisation. Never feed roots or seeds.)
    • Citrus (Citrus can cause gastric distress in larger amounts or if fed regularly.)
    • Chocolate (While there aren’t many sources to confirm whether chocolate is a great danger to goats, it does contain theobromine which can be toxic in a number of other mammals. There are limited studies indicating certain amounts can be toxic so it is best to use caution and avoid altogether.)
    • Nightshade “vegetables” (Use caution. Do not feed green, immature fruits or leaves, vines or roots of any nightshade vegetable, such as eggplant, tomatillo, pepper, or tomatoes.)
    • Onions (While goats have a greater resistance to toxicity issues than some other mammals, onions are not a great treat.)
    • Parsley (Parsley contains furocoumarins which can cause photosensitisation)
    • Potatoes (The skin, particularly green skin, and “eyes” contain glycoalkaloids and solanine toxins; leaves and vines can be toxic as well.)
    • Rhubarb (There are a number of factors that affect levels of toxins in rhubarb; the leaves are particularly toxic but it is better to avoid the whole plant as it contains oxalic acid. Cooking it may reduce toxin levels in the stems.)
    • Un-Pitted stone fruits (Pits can lodge in the intestines and pits contain toxins.)
    For more information on what you should feed sheep, check out our resource here.

    While this list isn’t exhaustive, it can certainly help you keep resident sheep safe, healthy, and happy!
