Animal products are not part of the detox program. The detox protocol is a raw food detox as well. Most if not all food should be consumed raw. Organic meat is a double edged sword. On one hand you have an animal pumped full of anti biotics and on the other hand you have an animal refused antibiotics if they are sick. Which they routinely are being that they are crammed in sheds. The amount of land required by the USDA to be considered free range is the size of a sheet of printer paper. Birds kept in such close quarters communicate diseases fast. I do not recommend any animal products when on a detox.  The main issue with detoxing is lessening the workload of the livers and kidneys so they can clean house. Animal protien is acidic to the body and forces the body to work overtime digesting the excess protein.
Almond milk is fine if you make it yourself. It's really not that hard to do if you have a good blender. If you can't blend it yourself you can buy it from the store but remember that it's pasteurized and probably has added sugars which you want to avoid.
Hope that answers your questions!
