Potatoes are among the best and most consumed vegetables in the world. We love them, especially when presented in the form of snacks like French fries, chips, tater tots, gnocchi, and a lot of other stuff.

But since potatoes are quite handy and snacking edible items, you might have thought about offering some of them to your hoofy friend. You are, without a doubt, absolutely into this vegetable, but can horse eat potatoes? What are the risks?

Read the full blog to comprehend the answer effectively.

Can Horses Eat Potatoes?

No, potatoes are toxic to horses.

Horses should not eat potatoes – not even in moderation – because of their poisonous and fattening effects on equines. Being a nightshade family member, potatoes can even be toxic to humans when consumed in excess, especially green or sprouted potatoes.

Why Potatoes Are Bad For Horses?

Here are two main reasons you can share potatoes with your equine friend.  


Potatoes contain two kinds of glycoalkaloid toxins – chaconine and solanine – that pose a toxicity risk to horses as well as humans. You must be thinking that when it is okay for us to munch on potato snacks all the time, then why we are not affected by the natural toxins present in potatoes.

Well, when cooked, these toxins break down, making potatoes safe for human consumption. Cooked potatoes also pose a lesser degree of toxicity threat to horses. On the other hand, uncooked potatoes pose a toxicity risk to both humans as well as horses.

Besides, when humans swallow any toxic item like potatoes, they might vomit, significantly decreasing the symptoms and long-term impacts. Horses cannot throw up due to stronger esophageal sphincters and are thus vulnerable to poisoning as they cannot get the toxins out of their bodies.

Nightshade Family Does Not Get Along With Horses!

Veggies belonging to the nightshade family of vegetables are high in alkaloid toxins – solanine and chaconine – making them toxic to horses and livestock. Therefore, you should refrain from feeding potatoes, tomatoes, bell peppers, and other nightshade veggies to your horse.


Besides toxicity, potatoes are also high in starch, and hence, have a high content of carbohydrates. A diet rich in carbohydrates increases the risk of obesity in horses.

If truth be told, potatoes are more fattening for horses than for human beings because the former have not evolved to run on too many carbohydrates. As a result, they easily get obese and gain unnecessary pounds. Obesity will not only lead to many other health issues but will also interfere with the learning abilities of your horse. If you have a dressage horse, gaining extra pounds is certainly going to affect his performance in shows.

Are Potatoes Safe for Horses in Any Form?

Potatoes, regardless of their form, are toxic or at least unhealthy for horses. The main ways of serving horses potatoes are raw, cooked, or processed. To understand better, see the detailed explanation of each way of serving below:

Raw Potatoes: Can Horses Eat Raw Potatoes?

Raw potatoes are toxic to not only horses but also humans as they contain a high amount of unbroken toxins – solanine and chaconine. And if raw potatoes are unpeeled, it would be even more toxic as potato peelings contain around ten times more solanine than potato flesh.

Cooked Potatoes: Can Horses Eat Cooked Potatoes?

Based on the above discussion, you might think that cooked potatoes must be okay for your horse because the toxin solanine is broken and no more poses the toxicity risk. However, despite safe solanine levels, it is strongly advised that you do not give potatoes to your horse, as it is always a possibility that cooked potatoes may still contain some level of unbroken solanine. Plus, even if solanine is completely removed, the fattening aspect of potatoes is still there.

In addition, if potatoes are cooked in oil instead of using steam or water, they turn out to be even more fattening.

Processed Potatoes: Can Horses Eat French Fries or Chips?

No, horses cannot eat french fries or chips. Processed potatoes such as French fries and chips contain a lot of additives and chemicals that can affect the digestive system of your horse.

Remember that not just potatoes, any processed food containing such ingredients, would be unhealthy for your horse.
