Do you know how to melt powdered milk (adjusted powder milk for baby/infant) with hot water over 70 ° C?

It is to sterilize pathogens in powdered milk.

Although it is a very small amount, powdered milk itself and melted powdered milk contain bacteria such as "Cronobacter sakazakii (Sakazaki bacteria)" and "Salmonella enterica (Salmonella bacteria)" and are regarded as problems.

• What is Cronobacter sakazakii (Sakazaki fungus)?
  Sakazaki bacteria may also be detected in the intestinal tract of humans and animals, as well as fruits and vegetables such as corn, cucumber and lemon. baby/infant (children under 1 year old), especially premature babies, immunodeficiency, and low birth weight infants, may cause "sepsis" and "necrotic colitis" may occur. When an adult is infected, the symptoms are considered to be quite mild.
  Sakazaki bacteria are found to be more common in the production environment of powdered milk than Salmonella bacteria, but according to the Health and Labor Sciences study, the amount contained in Japanese products is very small, one in 333 g. Has been reported.
• What is Salmonella enterica (Salmonella)?
  Salmonella is a bacterium that mainly inhabits the intestinal tract of humans and animals, and there are many types, some of which cause typhoid diseases and food poisoning such as diarrhea and fever. Salmonella bacteria are rarely mixed in the production process of powdered milk. After opening the powdered milk, it seems that it may be mixed when the powdered milk is melted or melted.

Both Sakazaki and Salmonella bacteria do not increase in dry powdered milk, but they can survive. In other words, it may be mixed in powdered milk after opening and survive for a long time.
(There have been reports that Sakazaki bacteria survived for more than a year in dried powdered milk.)

Sakazaki bacteria and Salmonella bacteria in powdered milk after dissolving can be suppressed by keeping them below 5 ° C, but if placed at a higher temperature (such as room temperature), they may increase rapidly. There is.

• Before making powdered milk, wash your hands with soap and water.
• Wash and disinfect the equipment you use, such as baby bottles and spoons.
• When dissolving powdered milk, use hot water over 70 ° C.
• Powdered milk dissolved in hot water should be poured into running water or put in a container containing cold or ice water, and cool it in a short time to breastfeed.
• After melting, throw away milk that was not used within 2 hours.
• Let's throw away the milk left behind.
