So, to sum it up in a sentence you can tape to your fridge: Eat shrimp ceviche within 48 hours, but ideally within the first 24 for maximum joy and zero regret. After that, you’re on a slippery slope to a bad time. And honestly? If you’re reading this and wondering if that ceviche from Tuesday is still good on Thursday… it’s not. Just let it go. Make a new batch. Your stomach—and your dignity—will thank you.
Now, go forth and ceviche wisely. And maybe buy a smaller bag of shrimp next time.
