is this product safe for a vegetable garden?

You could mix a small amount with the garden soil or you can use old coffee grinds and egg shells crushed instead of the of the manure.

This is a well composted product and rest assured I have used this for two years now and it's completely safe to grow your consumable vegetables. It does contain small quantities of poultry manure which I usually buy separately to amend my garden soil every year. It is organic and very safe to use however you should amend this product with either organic or chemically produced fertilizer to supplement.
