See "Zombie Collector" for a list of zombie mutant variants.
These zombies will appear onscreen with a visible health bar. You will encounter many of these while undertaking the Subterranea Missions, or you could enter the Quarantine Zone, kill any mutants you find, enter and exit a shop such as Matsuya and the mutants will have respawned.
