Travelers rarely take canned food with them because they weigh a lot. On the other hand, this is a wonderful provision: nutritious, takes up little space in a backpack and will allow you to eat well in the forest if a person goes camping for several days. If a person decided to travel, then he should know that not all canned goods are suitable for such a pastime.
Poisoning from canned food can be very serious. When buying, pay attention not only to the date of manufacture, but also to storage conditions. Some canned foods can lie for a long time, if you observe the temperature regime, and on the campaign quickly deteriorate. This is fraught with the fact that in nature, in the forest, there are no medical centers that can provide first aid.
For example, stew has a long shelf life. It is allowed to be stored for years. Canned fish is the most dangerous. They have a very short storage period, and elevated temperatures can further reduce shelf life. In case of hopelessness, the expired product can be consumed, but in this case it is necessary to cook for a long time and when extracting the contents of the can, do not touch the mass that remains on the walls.
Checking canned food
When buying and immediately before use, it is worthwhile to conduct several verification activities. If the can is tightly closed or swollen, you should immediately refuse such a product. After opening, canned food can be checked during cooking. If bubbles appear during heating, then most likely the product is spoiled.
Opening the jar, you should carefully examine its contents. If dark spots or molds are noticed in the sauce, do not hesitate, the envelope is spoiled. If dark spots are on the bank itself, then you should not worry. They appeared during storage and will not bring harm to the human body. Never leave the contents of the jar for later. You should immediately eat the product. The next day, even fresh canned food can become spoiled.
Canned packaging may be damaged during transport. This can be found out if you carefully examine the jar. Also, the can can be lowered into the water. If it pops up, then the contents are not suitable for use. It is not worth spending water on such inspections if the water supply is limited. If there is serious suspicion that the canned food has deteriorated, it is better not to risk it, and throw the bank away and move in the direction of the village. Without food, a person can live long, but without water - no.
