How long does weed killer last

How long does weed killer last before the surrounding plants are good to eat? I like harvesting wild plants to eat, plantain, dandelion, and many others. My concern is the weed killer spray that most cities use. How long does weed killer last before the surrounding plants are good to eat? Thanks.

Eating plants that have been sprayed by unknown herbicides would not be recommended.
