How Long Does Tilapia (Raw) Last?

Tilapia's short 1-2 day fresh fridge window reflects how quickly any lean fish's delicate flesh starts to break down once it's out of the water, faster than a denser cut of meat would.

A strong ammonia-like smell, rather than tilapia's normal mild, faintly sweet scent, along with flesh that's gone from firm and springy to soft and separating easily, are the clearest signs it's spoiled. A milky, cloudy slime forming across the surface — distinct from the fish's natural moisture — is another reliable warning sign worth checking for specifically, since fish can look deceptively fine at a glance even once it's turned. Fish needs to reach 145°F internally when cooked, and that threshold applies whether the fillet came fresh from the counter or was previously frozen and properly thawed.

Fish left unrefrigerated for more than an hour or two, especially on a warm day, spoils considerably faster than the general fridge window suggests, since fish flesh breaks down at room temperature noticeably faster than a denser cut of meat would.

Storing tilapia toward the coldest part of the fridge, often the back of a lower shelf rather than the door, gives it the best chance of reaching the fuller end of its short 1-2 day window.

A fillet that's developed a strong, distinctly fishy smell noticeable through its packaging, well beyond tilapia's normal mild scent, is often far enough along in spoiling that it's not worth opening the package to double-check with a closer look.
