Can you tell me how antibiotics used in animals and agriculture lead spreads of resistant strains to human populations?

In brief: Two ways

Giving antibiotics to animals will kill many bacteria, but resistant bacteria will survive and multiply.
When the animal is slaughtered and processed, these bacteria can contaminate meat and humans who handle it. Also, bacteria can reach the environment/water and plants via animal feces, which we can then ingest. This way we "inherit" the resistant organism.
