Further information: Animal product and Rendering (food processing)
An animal product is any material derived from animals, including meat, poultry, seafood, eggs, dairy products, honey, fur, leather, wool, and silk. Other commonly used animal products are beeswax, bone char, bone china, carmine, casein, cochineal, gelatin, isinglass, lanolin, lard, rennet, shellac, tallow, whey, and yellow grease. Many of these may not be identified in the list of ingredients in the finished product. There is disagreement among groups about the extent to which all animal products, particularly products from insects, must be avoided. The Vegan Society in the UK will only certify a product as vegan if it is free of animal involvement as far as possible and practical; the development and manufacture of vegan products must also not involve animal testing. Neither the Vegan Society nor the American Vegan Society consider the use of honey, silk, or other insect products to be suitable for use, while Vegan Action and Vegan Outreach regard that as a matter of personal choice.
