    Rice And Bacteria

    l recently heard, cooked rice can develope a bad bacteria, in as little as 30 to 40 minutes. lt was also told, rice is one of the main courses of food poisoning.

    well that I have never heard of. Hell they cook their food at 6am and then eat it all day without ever putting it in the refrigerator. That would seem to be more of a cause.

    I've heard that cooked rice should be allowed to cool down before storing in a fridge to prevent bacteria growth. Personally i'm more concerned about chemicals.

    Nonsense, that's an old wives tale.
    Bacteria grows in warm food (which is why we use refrigerators) The quicker the food is cooled (by putting it in the 'fridge for example) the less opportunity for bacteria to grow.

    Was actually referring to the OP's statement below....

    l recently heard, cooked rice can develope a bad bacteria, in as little as 30 to 40 minutes. lt was also told, rice is one of the main courses of food poisoning.

    2 statements that still haven't been proved to me....yet.

    Although one of the links does say you can get ill 30 mins after eating bad rice not 30 mins after eating freshly cooked rice.
    I would post pictures but life's too short.

    It's all about time temperature abuse.

    Time temperature abuse occurs when food is not stored or held at required temperatures.
    45 to 135 F is the Danger Zone for contamination from memory.

    Raw / uncooked, not cooked / reheated properly at high enough temperatures to kill microorganisms, foods not cooled properly is the main problem.
    The time a food is allowed to remain in the Danger Zone (favorable to the growth of microorganisms) dictates the level of contamination and risk i.e. one bug turns into 2 bugs, two to four etc,. etc.

    30-40 min to me, seems to be too short a period of time for rice to go off?
    Getting sick from bad rice, unless it is a chemical intevention, usually 8-16 hours is the time for the effects of food bourne illness to kick in

    Thailand is very lucky to have a pleantiful supply of fresh food, relatively short turn around times until it reaches the table and a culture of buying / eating out creating a fast turnover of perishable stock.

    The down side is that I would estimate that less than 1% of the Thai retail food handling industry has any knowledge of Time Temperature Abuse, proper food handling practices (HAACP). It is only that the food tastes good, few get sick that many remain in business (or move ther cart or resturant to the next soi)

    Mine too, stupid old bat, That's why they're called old wives tales.
    Where do they get these ideas?

    If you want to be really paranoid freeze all meat to -20C to kill all parasites. Then cook it hot to kill all bacteria.

    Then eat it piping hot before any chance of infection.

    And don't forget your tin foil hat.

    I did hear years ago about a food poisoning outbreak on the news in the uk that was traced to rice at a buffet restaurant and their practice of of not employing the boiled rice container until the end of the day. they were dumping the new rice on top of the old. This allowed some kind of 'parasite' to grow as cause dease. They didn't really elaberate on what the parasite was, I cannot find any reference to one on the internet. So I assume they meant your normal unpleasant food poisoning bugs.

    Room temperature in thailand is very nice for bugs to grow. I do my own bacterial fermentations of milk and stuff and in the uk I would have to heat stuff to thai room temperatures to get those bugs growing fast. Thailands not the place to leave any cooked foods that could culture germs lying around at room temperature for any length of time before eating it. however its great for for some yogurts.

    Saying that I have not had food poisoning in thailand often, and I have never had a problem for years since if got a bit pathological about washing my hands immediately before handling food under any circumstances. Its made me think that surfice-hand-mouth tyransfer is an important vector for food poisoning in Thailand as it is for winter vomiting disease in the uk.

    Freezing is a good way of killing weevils and their eggs in rice, assuming you doint like extra protein in your rice.

    A good first step is to drop it in and rinse it around in cold water. Most of the insect debris floats to the surface and can be skimmed off.

    Although when you see how much there is, you may not eat rice ever again.

    We rinse the uncooked rice 3 times,then add filtered water for cooking,we also always cook enough for 2 meals so what is left over is either used the same day.Or goes in the fridge last thing at night,then either used for breakfast or midday lunch.just heat it up again in the rice cooker.Never had a problem,but we seldom use it after a 24 hour period as it starts to smell off around that time period.

    So, what did they do before modern refrigeration?

    No one fell ill.

    Even if we cook rice at 8am it will stay out all day to around 10pm until it goes in the fridge.We sometimes forget,if it goes in the fridge its always ok,but around 50% of the time if left out it goes off overnight.
    Don't forget a lot of places in Thailand still use ice to keep things cool.

    This is correct.
    You can get food poisoning from rice if you don't store it in the fridge after cooking.
    What makes you sick is Bacillus cereus, says CSIRO food microbiologist Cathy Moir. These bacteria produce toxins that will give you a mild vomiting illness shortly after you eat the contaminated food (sometimes it only takes 30 minutes to get sick).

    I suspect most foods which are cooked and left to stand for a number of hours at room temperature would "encourage" bacteria to grow.

    A rumor that's pure hogwash...
    If this unsubstantiated conjecture were true, you'd be reading about deaths of massive numbers of the Thai population!!
