Why is chocolate contaminated with Salmonella? How to tell if a food is infected with Salmonella in daily life? That's what you need to know

Chocolate why
Contaminated with Salmonella?
Chocolate is rich in sugar fats, the production process is complicated, and there is a possibility of contamination by microorganisms, especially Salmonella.
As a foodborne pathogen that everyone is more familiar with, Salmonella is the most common in meat, eggs and milk. Chocolate is most likely contaminated because the raw milk powder is contaminated with Salmonella.
In addition, because the oil contained in chocolate will save Salmonella from being killed by stomach acid, eating contaminated chocolate will be more likely to cause food poisoning.

How to tell if food is there
Contaminated with Salmonella?
What are the symptoms of eating?
Although spoilage and odor are the main sensory identification means for food contaminated by microorganisms, the growth and reproduction process of Salmonella does not decompose protein components, and it is difficult for the public to use the naked eye to distinguish whether food is contaminated by Salmonella under the condition of non-laboratory culture testing.
Due to the high probability of food poisoning after eating food contaminated with Salmonella, Salmonella has become a foodborne pathogen under key control in countries around the world.
When Salmonella enters the human body, it can multiply in the intestine and enter the bloodstream through the lymphatic system. The main symptoms of poisoning are acute gastroenteritis, if the bacteria produce toxins, it will cause central nervous system symptoms, such as increased body temperature and spasms (body convulsions).

What else is there to eat
Easily contaminated with Salmonella?
Salmonella is found in many types of food, mostly meat, fish, eggs and milk.
However, there are also other strains of salmonella in the leaves of the plant, especially green leafy vegetables such as lettuce, arugula, coriander, basil, mint, cabbage, lettuce and so on. Salmonella typhimurium may be present in tomato, bell pepper, and cucumber leaves.
To prevent salmonella contamination, we must not only pay attention to the contamination of animal foods, but also beware of the contamination of vegetables and other plant foods.
Salmonella food poisoning is generally a disease that enters the mouth and is infected through the digestive tract. The reason why Salmonella can be widely present in the external environment is because it has a certain resistance to sunlight and so on. But its resistance to high temperatures is weak, and it can be killed at 80 ° C.
Therefore, in order to avoid salmonella contamination, when preparing food at home, when contacting raw meat, fish, egg shells, etc. before cooking and cooking, it is necessary to wash your hands thoroughly before continuing to cook, and it is best to use running water and hand sanitizer to wash your hands thoroughly.
Meat and eggs are cooked before being eaten, and all knives, cutting boards, and utensils are thoroughly rinsed with hot water. Also, a reminder: unpasteurized milk needs to be boiled and drunk.

Pick this type of food
What do I need to be aware of?
It's hard to shop for everyday shopping and choose food that isn't contaminated with Salmonella. If you have ever bought or eaten food that has been removed from the shelves due to salmonella contamination, you don't have to panic.
According to international food safety laws and mainland food safety laws, contaminated products are removed from shelves at the first time, and similar products may not be contaminated.
When choosing to buy fresh foods that are often eaten, such as eggs, milk and meat, especially eggs, we must remember that "freshness is king" and not be tempted by gimmicks such as "native eggs".
Try to choose eggs from large-scale chicken farms with health supervision and prevention and control measures for poultry diseases, and the eggs that are bought can be stored in the refrigerator, and do not buy damaged eggs. If you accidentally buy a cracked egg, be sure to cook it thoroughly before eating it.
