On dumpster diving/ dairy?

While dumpster diving, I've found quite a bit of dairy products: cheeses, yoghurts, and baked goods with eggs/honey. What are your thoughts on consuming food waste with animal products in it?

I find a lot of bagels (4-5 dozen a week), but the local variety is made with eggs and boiled in honey-water. The scale is alarming, and I feel like I should be eating them.

Would you consider someone 'vegan' if they were eating food waste that contained animal products?
