Can you grow edibles alongside poisonous plants like Lily of the Valley?

So I'm pretty much a beginner gardener with a pretty decent sized yard aiming to grow enough enough food that I can eat one meal out of my garden three times a week (I'd love to say every day, but who am I kidding?). There's already a raised garden bed in our yard which has hyacinths, asiatic lilies and lily of the valley. They're beautiful flowers and make for a great spring show. The bed that they are in also has wonderful soil. It's been cultivated and cared for over a span of 30 years (my partner who is much older than me used to grow certain plants in this garden in the 70s). I'm wondering if it is safe to mix edibles in with bulbs that produce poisonous plants. I'm also wondering if the soil is safe? If I pulled the bulbs out and put them somewhere else, would the soil still be a problem? Sorry if it's a silly question, but no one in my family or close circle of friends likes to grow edibles.

It's perfectly fine to grow food in there. Toxins from plants don't translocate into other plants. The only danger would be that if you were growing root crops in there and somehow mistakenly harvested an unnoticed bulb of one of the poisonous ornamentals mistaking it for your crop. A fairly common instance of this is mistaking daffodils and related bulbs for onions. So maybe stay away from onions and garlic and such like until you are sure all of the flower bulbs are gone for good.....
