1. Pre-fried foods
The market often sells pre-fried foods such as fried spring rolls, fried pork, fried fish... They look delicious, are reasonably priced and convenient. Housewives just need to buy them and can use them right away. However, this type of food poses a very high risk of food safety. It is difficult for you to know exactly what ingredients the seller uses for the dish, and whether the processing is hygienic or not.
In addition, the seller can use the same cooking oil over and over again to save money. Reusing cooking oil many times not only reduces its nutritional value but also causes deterioration, creating toxins in the oil. The food residues that remain in the oil and are not completely removed are also pathogens that cause illness in humans.
2. Pickled foods
At the market, you can also easily find pickled foods such as pickled cucumbers, pickled eggplants... Pickled foods, although very delicious, contain a large amount of sodium. Consuming too much salt will affect the stomach, blood pressure, and cardiovascular system.
In addition, the dusty environment in the market, flies, mosquitoes, etc. will make the food unhygienic. If the pickled food is stored in paint cans, it will be even more unsafe for the user.
3. Pre-ground meat
Pre-ground meat can be a mixture of lean meat, leftover meat, uncooked meat, pork fat, etc. When they are ground, it will be difficult for you to distinguish whether it is fresh meat or not.
You should choose a piece of fresh meat and let the seller grind it or take it home to grind it yourself.
4. Sausage
Sausage is one of the foods that many people love but is often unclear about its origin and expiration date. It is best to only buy sausages with labels and packaging that clearly state the manufacturer, ingredients, and expiration date.
