“Got a sweet tooth? Think twice before picking up a Mars candy bar! You should know that candymaker Mars, Inc.—creator of M&M's, Snickers, Twix, Dove, Three Musketeers, Starburst, Skittles, and other candies—funds deadly animal tests, even though there are more reliable human studies and not one of the tests is required by law.
Mars is currently funding a deadly experiment on rats to determine the effects of chocolate ingredients on their blood vessels. Experimenters force-feed the rats by shoving plastic tubes down their throats and then cut open the rats' legs to expose an artery, which is clamped shut to block blood flow. After the experiment, the animals are killed. Mars has also funded cruel experiments in which mice were fed a candy ingredient and forced to swim in a pool of a water mixed with white paint. The mice had to find a hidden platform to avoid drowning, only to be killed and dissected later on. In yet another experiment supported by Mars, rats were fed cocoa and anesthetized with carbon dioxide so that their blood could be collected by injecting a needle directly into their hearts, which can lead to internal bleeding and other deadly complications.”
