Hundreds of thousands of sweets were discovered on the freeway in Wisconsin, America, after a truck accident. Mars, the company that makes Skittles, says it doesn't know why this batch was potentially used as feed for livestock. It is reported that some farmers give their livestock sweets, because it is cheaper than corn. 
The county sheriff revealed on social networks that the candies were red Skittles, although they did not "have the standard 'S' signature on them." Some locals say they are worried that the animals were eating Skittles. However, others argue that if people can eat pastry sweets, then they should be useful for animals. 
Linda Kurz, Mars's corporate environmental manager, says the firm sells unused ingredients to customers, who then mix them with other materials to make animal feed. However, the company does not sell them directly to farmers. Nutritionists say that if sweets are used in animal feed, they are mixed with other ingredients to achieve the right kind of dietary supplement. For example, it is known that British farmers feed their animals with bread or cookies.
A National Farmers Union adviser, Tom Drecap, says: "Very often, the by-products of the rural and food industries are used to supplement livestock feed." Not only are they safe and nutritious for animals, they can also be a great way to improve livestock diets. "
