You generally shouldn't eat 4-day-old rice because it carries a risk of Bacillus cereus bacteria growth, which can cause food poisoning, and its toxins aren't destroyed by reheating; while some sources say up to 4-6 days in a good fridge, it's safest to eat it within 24 hours or freeze it immediately, discarding if it smells sour or looks slimy.
Leftover rice can be stored in the refrigerator and safely eaten around four days after being cooked or purchased. However, if you're unsure, you can always throw it away to be on the safe side. I hope that this answers your question.
The general rice-to-water ratio is as easy to remember as 1, 2, 3: 1 cup rice + 2 cups water = 3 cups cooked rice. However, the actual ratio varies depending on the cooking method and the type of rice you're using. The ratio is generally 1:1 if you're using a rice cooker, but follow the manufacturer's instructions.

Reheated rice syndrome is food poisoning caused by Bacillus cereus, a bacteria that spreads in improperly cooled starches. Throw out rice and other starchy foods that have been left out at room temperature for more than a couple of hours.
The U.S. Department of Health and Human Services gives us four to six days to eat cooked rice (and up to four days for most other leftovers), so long as it's been stored in a fridge that's 40 degrees Fahrenheit or cooler, and never left out for more than two hours (or at most one hour on particularly hot days).
Illness from Bacillus cereus usually occurs 1 to 6 hours after eating contaminated food. Symptoms include nausea, vomiting, and diarrhoea. Most people recover within 6 to 24 hours.
It's safe to eat cold cooked rice if it's cooled down quickly, stored in the fridge and eaten within 24 hours. To store cooked rice safely: chill it as quickly as possible, ideally within 1 hour. take it out of the rice cooker, steamer or pan to cool it down faster.
Cooking contaminated food at recommended temperatures destroys the vegetative cells of B. cereus. Heat-resistant endospores of this bacteria are more likely to survive cooking and start growing again (germinate) when the food is cooled gradually over an extended period of time.
The "555 rice rule," more commonly known as the 10-5-5 rule, is a method for cooking perfect, fluffy rice in a pot by boiling vigorously for 10 minutes on high heat, simmering covered on low heat for 5 minutes, and then steaming with the heat completely off for a final 5 minutes, ensuring you don't lift the lid during cooking.
You can get food poisoning from eating reheated rice. It's not the reheating that causes the problem, but the way the rice has been stored before it's reheated. Keep rice in the fridge for no more than one day until reheating. When you reheat any rice always check the dish is steaming hot all the way through.
Reheated rice syndrome is food poisoning from Bacillus cereus. It usually starts within hours after eating cooked rice that sits at room temperature for too long after cooking. Symptoms include vomiting, diarrhea, or stomach cramps and typically resolve in 24 hours. Most people recover quickly with rest and fluids.
“Start with easy-to-digest and soft foods, like scrambled eggs, almond butter on a banana, or peanut butter toast,” says Stuart. Pairing protein-rich foods such as nut butters with bananas or toast can help balance blood sugar and keep you feeling full longer, Stuart explains.
Discoloration (usually a pale or darker yellow hue), a sour or rancid smell, or visible mold spots are all indications that something has gone wrong. How should dry rice be stored for maximum shelf life?
The symptoms of this illness are enough to scare anyone— nausea, vomiting, upset stomach, cramps, fever—and though they typically only last 24 hours, some cases can be more serious.
B cereus is a common bacterium, present ubiquitously in the environment. It can form spores which allows it to survive longer in extremes of temperature. Consequently, it is found as a contaminant of various foods, ie, beef, turkey, rice, beans, and vegetables.
You might be able to eat cooked rice after 5 days if it was refrigerated within an hour of cooking and stored in an airtight container, as FoodSafety.gov suggests 4-6 days is okay, but many experts recommend a more cautious 3-4 days, so it's best to check for any off odors, discoloration, or a slimy texture before reheating thoroughly (to 165°F/74°C).
A general procedure for cooking long grain white rice is the 1-2-3 rule: 1 part uncooked long grain or medium grain rice, plus 2 parts liquid, equals 3 parts cooked rice. Bring 2 cups of *liquid to a boil in a 2-quart heavy saucepan. Stir in 1 cup of rice.
cereus, assume that rice has gone bad if you haven't refrigerated it within one to two hours of cooking or if it's been in the fridge for more than four days. If you keep the rice around longer, you may eventually notice mold develop. But you should use or toss rice long before that happens!
