High temperature strikes, in addition to heatstroke prevention, you also need to pay attention to these pathogens!

After the rainstorm, the heat hit. Recently, the Central Meteorological Observatory issued a high temperature orange warning. Xiaobian’s current state is that it’s just a slap in the face, and Xiaobian becomes a barbecue~

Look at the dress index chart, where you stay red is not red?

Of course, in the midsummer, in addition to the heat, there are beer, skewers and camping.

But do you know that summer temperatures are high and humidity is high, which is especially suitable for the propagation of pathogenic microorganisms, leading to multiple infectious diseases, such as diarrhea, food poisoning, acute gastroenteritis, hand, foot and mouth disease. Today, Xiaobian will talk to you about the food-borne pathogenic microorganisms.

E.coli

According to the pathogenicity, Escherichia coli is divided into enterotoxin-producing Escherichia coli, intestinal invasive Escherichia coli, intestinal pathogenic Escherichia coli, and intestine. 5 kinds of concentrated adhesion Escherichia coli and enterohaemorrhagic Escherichia coli. The optimum growth temperature is 37 ° C, and the growth temperature ranges from 15 to 46 ° C. It can survive for weeks to months in natural water and last longer in lower temperature feces.

Causes illness: diarrhea, food poisoning.

Susceptible food: all kinds of cooked meat products, raw cold food, eggs and egg products, cheese and vegetables, fruits, beverages and other foods.

Vibrio parahaemolyticus

The optimum growth temperature is 37 ° C, and the survival ability is strong. It can survive for more than 1 month on rags and cutting boards, and can survive for 47 days in seawater. It is sensitive to acid, and it dies in ordinary vinegar for 1-3min. It has low resistance to high temperature and can die at 5°C at 56°C.

Caused by symptoms: acute diarrhea, gastroenteritis, food poisoning.

Susceptible foods: seafood such as fish, shrimp, crab, shellfish and seaweed.

Listeria

It is widely distributed in nature and is easily spread by various means. It can survive at 0-45 °C, especially in the refrigerator at the refrigerating temperature, and even survive in the freezer at -20 °C for one year. In addition, it has the ability to resist dryness and high salt tolerance. Pregnant women, the elderly or other people with low immunity are susceptible.

Caused by the disease: sepsis, meningitis, endocarditis can also cause stillbirth in pregnant women.

Susceptible foods: meat and meat products, milk and dairy products (raw and soft cheese), aquatic products, ready-to-eat foods (cooked meat) and vegetables.

Norovirus

It has strong viability, can survive in the temperature range of 0-60 ° C, and can withstand acid and chloride ions in drinking water. It is highly infectious and is mainly transmitted by the intestines and can be transmitted through contaminated water sources, food, articles, and air.

Causes illness: non-bacterial diarrhea.

Susceptible food: drinking water and aquatic products.

salmonella

Intestinal bacteria, the optimum breeding temperature is 37 ° C, can be multiplied above 20 ° C, not easy to breed in water, but can survive for 2-3 weeks, the refrigerator can survive for 3-4 months, the feces in the natural environment It can survive for 1-2 months.

Causes symptoms: gastroenteritis, typhoid fever and paratyphoid fever.

Susceptible food: meat and meat products, eggs, drinking water.

Staphylococcus aureus

The optimum breeding temperature is 37 ° C, and the growth temperature range is 6.5-46 ° C, which can produce enterotoxin. It is ubiquitous in nature, and can be found in air, water, dust, and human and animal waste. It can survive in dry pus and sputum for 2 to 3 months.

Caused by the disease: Staphylococcus aureus enteritis, food poisoning, diarrhea.

Susceptible foods: milk and dairy products, raw meat and meat products.

Enteroviruses such as Coxsackie virus

It is easy to cause infectious diseases, mainly through the intestinal tract, but also through the respiratory tract or from contaminated hands, food, clothing, utensils, etc. High temperature and high humidity weather is especially suitable for the survival, transmission and reproduction of enteroviruses.

Caused illness: hand, foot and mouth disease, etc.

Susceptible food: food that can be exposed to pathogens such as drinking water.

Campylobacter, Shigella, Yersinia, and Bacillus cereus are also common foodborne pathogens. People infected with these pathogens often cause diarrhea, gastroenteritis, and food poisoning. The high temperature in summer makes these bacteria proliferate faster, and is a high season for diseases caused by food-borne pathogens.

In addition, high temperature and high humidity in summer make mosquitoes and flies become a kind of vector organism, Xiaobian warm reminder, pay attention to prevent mosquitoes, prevent the spread of dengue virus, yellow fever virus, Japanese encephalitis virus and Zika virus.

Zhuocheng Huisheng is committed to the development of public health, and has independently developed a series of products for detecting food-borne pathogens, which can identify relevant pathogenic microorganisms efficiently, quickly and accurately, for the investigation of poisoning epidemics, epidemic monitoring, infectious diseases. Provides powerful tools for monitoring, food safety monitoring, food inspection, etc. For more information, please call us.

Extra! Extra! Zhuo Cheng Xiaobian has compiled tips for preventing foodborne intestinal diseases and mosquito-borne vector-borne diseases. Please pay attention to your attention!

Tips for preventing foodborne intestinal diseases

• Develop a good habit of “drinking water, eating cooked food, washing hands frequently”;

• Eat less on the street stalls with poor sanitation, and eat less salad and meat barbecue foods outside;

• Pay attention to the family's food hygiene, do not eat leftovers, cut vegetables and vegetables, and separate the food, do not use the refrigerator to save food for a long time.

Tips for preventing mosquito-borne vector infections

• Clean up accumulated water and garbage in time to prevent mosquitoes from breeding;

• Light long-sleeved trousers should be worn when going out, and the insect repellent should be applied to the exposed skin;

• When traveling abroad, according to the actual situation in the local area, timely vaccination of relevant vaccines.
