When in doubt, always rely on your sense of smell and taste to steer you clear of possible food-borne illnesses. However, this should be judged on a case-to-case basis. Whether they were grilled for a BBQ or sauteed in garlic, food safety guidelines around the world emphasise a use-by date for prawns to know if they’re expired.īoth raw and cooked shrimp (regardless of cooking method) are safe in the fridge for up to three days from the date of purchase. No, the cooking method doesn’t make a difference. Does the cooking method affect shelf life? Don’t keep spoiled food in your fridge: toss it out immediately to avoid contaminating any other food that you’re storing. These spots are mould, and they can cause serious food poisoning if you eat them. Another indicator that your prawns are not safe to consume is if there are green or blue spots growing on them.
