The present invention measures the current temperature and humidity of a workplace handling food in real time, and the measured data compared to the food poisoning forecast index predicting the growth of food poisoning bacteria and food deterioration, and informs the user and at the same time room temperature and humidity It is to provide a food poisoning forecast index notification device that can automatically adjust to prevent food poisoning and contribute to public health.

You may have a couple or two experiences of eating badly in the summer. Nowadays, news of group food poisoning has often come about after school lunches or after wedding parties or wedding receptions.

Although there is no legal definition of food poisoning, the term "food poisoning" in Article 210 of the Food Sanitation Act refers to an infectious or toxin-type disease caused or believed to be caused by microorganisms or toxic substances harmful to humans due to the ingestion of food. It is defined.

If food poisoning is classified according to the causative agent, it can be classified into bacterial food poisoning, chemical food poisoning, natural poisoning food poisoning, and food poisoning caused by microbial toxic metabolites. There are many kinds of toxic substances in each class, and toxic substances are widely distributed in many foods, even if they are not harmful enough to cause immediate health, and can cause chronic poisoning, carcinogenicity, mutagenicity, teratogenicity and allergic reactions. It may cause.

The causes of food poisoning are classified into toxins produced by microorganisms and microbial infections.However, food poisoning bacteria, unlike infectious diseases, have to be eaten when food poisoning bacteria are contaminated with food and consumed in a certain amount (about 1 million). do. Therefore, to prevent food poisoning, cleanliness, sufficient heating and rapid intake are the most important.

The growth of food poisoning bacteria multiplies fold in a short time, and the factors that influence the growth are temperature and humidity. If food poisoning conditions are good, the growth period of one animal to two is very short (generation period) so that one may grow to millions after 4 hours.

Recently, due to global warming, the food poisoning trend is increasing due to the abnormal high temperature phenomenon in the early spring and early autumn, and the food poisoning pollution incidents at school meal facilities are increasing due to problems in food cooking or storage at mass meal facilities.

In order to prevent food poisoning, care should be taken in the cooking and pretreatment of foods, but the storage location and time of cooked foods are also important to prevent food poisoning in summer.

Since the incidence of food poisoning is very high under the following climatic conditions, special attention is required for cooking, handling and storage of food.

-If the temperature is above 25 ℃ and below 30 ℃ and the relative humidity is 80%, it is expected to last about 6 hours

-If the temperature is above 30 ℃ and the relative humidity is above 70%, it is expected to last about 6 hours

-When temperature over 30 ℃ lasts more than 10 hours

-If the relative humidity is above 90% for more than 24 hours

-When the temperature rises sharply above 10 ℃ daily

-There are more than 10,000 enteritis vibrio bacteria per g and enteritis vibrio contamination.

Recently, as a way to prevent food poisoning in the summer, it is difficult to calculate the storage time of cooked foods, so the Meteorological Administration has developed a food poisoning index that indexes the time that food poisoning can occur according to the temperature of the day in cooperation with the Korea Food and Drug Administration. .

'Food Poisoning Index' is a quantitative and numerical concept developed to prevent food poisoning in summer and for national hygiene. It is an index that indicates the risk of food poisoning by microorganisms according to the temperature of summer day. The food poisoning induction time was indexed using E. coli, an indicator microorganism, as a model. The growth time (doubling time) according to the specific growth rate of (doubling time) is a value expressed as a percentage.

The food poisoning index means a ratio of the time that can cause food poisoning at the optimum conditions and the time that can cause food poisoning at each temperature.

 <Food Poisoning Forecast Index>

Exponential range Condition Other  Index 86 or higher When the food is left at 35 ℃ or higher, food poisoning such as Salmonella, Staphylococcus aureus, Enteritis Vibrio bacteria, etc. is extremely concerned after 3-4 hours.  Handle foods with extreme caution and risk of food poisoning  Index 53 to 85 If food poisoning bacteria such as Salmonella, Staphylococcus aureus, Enteritis Vibrio bacteria are easy to grow after 4 ~ 6 hours with 30-35 ℃ of temperature, food should be eaten immediately and caution should be taken in cooking facilities.  Handling of cooking facilities, warning of food poisoning  Index 30 to 53 If the temperature is 25 ~ 30 ℃ and 6 ~ 11 hours pass, food poisoning may occur due to food poisoning bacteria enteritis Vibrio, Salmonella and Staphylococcus aureus.  Food poisoning concerns, food poisoning caution  Index 10-30 Food poisoning caused by Staphylococcus aureus, Salmonella, etc., which are food poisoning bacteria, may occur at temperatures between 20 ° C and 25 ° C.  Concerns about food poisoning and food handling

The food poisoning index is a ratio of the pH and water activity at which the food poisoning can be induced at the optimum conditions and the time that can cause food poisoning at each temperature, the meaning of the food poisoning index 100 is the optimum conditions (40 C, pH = 6.5-7.0, water activity = 1 ~ 0.99), it takes 3.5 hours for food with 1000 initial bacteria to grow into 106 bacteria that can cause food poisoning, and food poisoning index 80 takes 3.5 hours to develop food poisoning. Divided by 0.8, or 4.4 hours, and the food poisoning index 50 means that 3.5 hours divided by 0.5, that is, 7 hours.

Therefore, if the food poisoning index is 35-50, food poisoning may occur within 10 hours, and the food poisoning warning may be predicted. If the index is over 50, food poisoning may occur within 7 hours.

In the food poisoning index, the absolute value of the forecast area is expressed as a percentage based on only the temperature condition affecting the growth of food-related microorganisms. It is currently provided through the Internet (Industrial Meteorological Information Center).
