Forgot this in the fridge… now what?

So, this entire gallon of milk is from our Nigerian Dwarves. It got pushed to the back of the fridge and forgotten about. It is from May 13, 2024. It is currently February of 2025. I don’t make butter, cheese, or soap. Just milk to drink.

Do I need to pour it out? Is it going to explode? Just looking for some advice😬
