Poisoning
Sandwiches sold on the street may not ensure food safety and hygiene. Some meats, sauces… used as fillings often have no clear origin or are not prepared cleanly.
Not only that, the old, dirty newspaper used to wrap the sandwiches and the vendor's unhygienic hands are also causes of the unhygienic situation. That is why many cases of poisoning from eating street sandwiches have been quite common recently.
Diarrhoea
Street sandwiches that are not well preserved are among the foods most easily contaminated, including the bacterium E. coli, a bacterium that causes diarrhoea, cholera and various intestinal diseases.
Many people with poor digestion often get diarrhoea and the digestive diseases mentioned above after eating street sandwiches because the sandwiches are not hygienic. Moreover, many stalls are set up in unhygienic, damp places, even right next to wastewater without any concern, causing diseases to increase more and more.
Cancer
Eating food of poor quality and the habit of sitting around street-side stalls eating and drinking are both unhygienic and cause serious diseases for the body, including cancer. Ingredients of unclear origin, possibly containing chemicals, expired, plus polluted air, dust and unhygienic eating places cause the body to be poisoned, damaged and to form tumours that directly affect many other organs, causing cancer.
The vendor not cleaning cooking utensils, not washing hands before preparing food, harmful processed food, and eating in a chaotic environment (a street with many passers-by, a makeshift, dirty spot…) can easily cause you to contract diseases transmitted through food and drink such as hepatitis, cholera, dysentery, typhoid…
Harmful to the kidneys
Fillings put into the sandwich such as meat, sausage, sauce, mixed vegetables… all contain a lot of salt, exceeding what the body needs. So eating too much will cause the body to swell due to water retention, which is not good for either the kidneys or the cardiovascular system.
Seriously declining health
Regularly eating street sandwiches means the body does not take in enough necessary nutrients, and the unhygienic food stalls easily cause illness, making the body increasingly exhausted, easily infected, affecting life and study.
