Misc Fried Rice Syndrome

I just read an article in sciencealert.com about a food poisoning referred to a fried rice syndrome. Anyway I can't put it up but my question to expert cooks is the article said there was no need to cool food before refrigerating. I always thought it was supposed to be cooled a little before putting away. I take soups and sauces and put them in cold water first. And things like spaghetti I put away after dinner. Should I change what I'm doing.

With modern refrigeration, any household fridge should be able to easily keep up with one or two hot dishes... 4 gall9ns of boiling soup... not so much!

Setting the pans in cold water is perfect. Get the temp to @150°, then refrigerate.

What you want to avoid is leaving a dish to cool all the way to room temperature... the danger zone for bacteria to explode is below 140°.

Essentially, either keep it hot, or chill as rapidly as possible.

4 gallons of soup - that's the batch that I make in my 16 qt stock pot. I usually pick a very cold day, with the temperature about freezing outside, to make it.

When it's done, the lid goes on, and the pot goes out to the unheated porch for a few hours, then into the fridge.

When we cook at church, we cool things before sealing them up in the fridge. Our "chief" cook ran a grocery/diner for years, his son has restaurants and they both say to cool things before putting in the fridge. If you do have to put something warm in the fridge don't seal it. Leave a corner of the lid or foil open so the heat can escape.

It's not so much letting the heat escape, as it is creating a vacuum with a closed lid.

Been there, done that.

Viral Video Spikes Fears Over Fatal Dangers of 'Fried Rice Syndrome'

Viral Video Spikes Fears Over Fatal Dangers of 'Fried Rice Syndrome'​

The Conversation

A condition dubbed "fried rice syndrome" has caused some panic online in recent days, after the case of a 20-year-old who died in 2008 was resurfaced on TikTok.

"Fried rice syndrome" refers to food poisoning from a bacterium called Bacillus cereus, which becomes a risk when cooked food is left at room temperature for too long.

The 20-year-old college student died after reportedly eating spaghetti that he cooked, left out of the fridge, and then reheated and ate five days later.

Although death is rare, B. cereus can cause gastrointestinal illness if food isn't stored properly. Here's what to know and how to protect yourself.

What is 'fried rice syndrome'?​

Baccilus cereus is a common bacteriumfound all over the environment. It begins to cause problems if it gets into certain foods that are cooked and not stored properly.

Starchy foods like rice and pasta are often the culprits. But it can also affect other foods, like cooked vegetables and meat dishes.

Certain bacteria can produce toxins. The longer food that should be refrigerated is stored at room temperature, the more likely it is these toxins will grow.

B. cereus is problematic because it has a trick up its sleeve that other bacteria don't have. It produces a type of cell called a spore, which is very resistant to heating. So while heating leftovers to a high temperature may kill other types of bacteria, it might not have the same effect if the food is contaminated with B. cereus.

These spores are essentially dormant, but if given the right temperature and conditions, they can grow and become active. From here, they begin to produce the toxins that make us unwell.

What are the symptoms?​

The symptoms of infection with B. cereusinclude diarrhoea and vomiting. In fact, there are two types of B. cereus infection: one is normally associated with diarrhoea, and the other with vomiting.

Illness tends to resolve in a few days, but people who are vulnerable, such as children or those with underlying conditions, may be more likely to need medical attention.

Because the symptoms are similar to those of other gastrointestinal illnesses, and because people will often get gastro and not seek medical attention, we don't have firm numbers for how often B. cereusoccurs. But if there's an outbreak of food poisoning (linked to an event, for example) the cause may be investigated and the data recorded.

We do know B. cereus is not the most common cause of gastro. Other bugs such as E. coli, Salmonella and Campylobacterare probably more common, along with viral causes of gastro, such as norovirus.

That said, it's still worth doing what you can to protect against B. cereus.

How can people protect themselves?​

Leftovers should be hot when they need to be hot, and cold when they need to be cold. It's all about minimising the time they spend in the danger zone (at which toxins can grow). This danger zone is anything above the temperature of your fridge, and below 60°C, which is the temperature to which you should reheat your food.

After cooking a meal, if you're going to keep some of it to eat over the following days, refrigerate the leftovers promptly. There's no need to wait for the food to cool.

Also, if you can, break a large batch up into smaller portions. When you put something in the fridge, it takes time for the cold to penetrate the mass of the food, so smaller portions will help with this. This will also minimise the times you're taking the food out of the fridge.

As a general guide, you can follow the two hour/four hour rule. So if something has been out of the fridge for up to two hours, it's safe to put it back. If it's been out for longer, consume it then and then throw away the leftovers. If it's been out for longer than four hours, it starts to become a risk.

The common adage of food safety applies here: if in doubt, throw it out.

It's also worth keeping in mind the general principles of food hygiene. Before preparing food, wash your hands. Use clean utensils, and don't cross-contaminate cooked food with raw food.

When we make spaghetti sauce (which we do now maybe once a year, because of lowering our carbs), we divide the batch into 3-4 containers and freeze all but one immediately. The unfrozen one typically gets put into the fridge for a bit until we cook the pasta for dinner (that same day), and then heated up and served.

That's how much we make at a time. Since we only fix it in the winter we set it outside on the deck on top of the grate of the BBQ grill. this allows air circulation to reach the thick bottom of the stock pot so that it cools faster. It's usually after dark and around or below freezing when we set it out so it cools fairly quickly. We then put it into a couple of gallon freezer bags to be frozen after setting out enough for the next meal into a container for the fridge.
 
In restaurants soups are poured into several inch deep pans to cool down faster in the walk in before being put into tub style containers for longer term refrig or freezing.
Have also seen “ice paddles”, an X shaped bottle thingy with mucho surface area.
Several sizes.

Students. Five days out of the fridge? Yep..that ain't smart. :lol:
Think I heard about this a long time ago. Extreme stupid is ageless.
