Specialist Doctor II HOANG NGOC QUA, Head of the Department of Artificial Kidneys at Children's Hospital 2 (HCMC), answered: If you like pickled foods, you should choose a reputable, long-standing traditional brand to use, this will be safer than the "homemade" style. Because the traditional brand name is food that is disinfected (preservative).
In addition, when processing food, production facilities have standard formulas for salinity and incubation time. When ensuring salinity and acidic pH standards will prevent bacteria from growing. In fact, some home-made foods and foods always show off no preservatives and are easy to ferment "young" (not enough days). At this time, the acidic pH is not acidic enough to disinfect. Besides, if salt is not salty enough (for fear of high blood pressure) there is also a risk of anaerobic bacteria poisoning.
In particular, children under 12 months old should not eat or drink honey or brush their tongue, because the pH of gastric juice in children under 12 months is not acidic enough to disinfect. If honey has spores of anaerobic clostridium bacteria, it will cause poisoning for children.
