Introduction
Clean feeding equipment is just as important as safe milk storage. Poor hygiene can cause bacteria to multiply quickly in breast milk, leading to diarrhea, infections, and malnutrition in infants. With simple steps, mothers and caregivers can keep bottles and storage containers safe, whether at home, hospital, or in low-resource settings.
1. General Principles
-
Always wash hands with soap and clean water before handling bottles, cups, or containers.
-
Use dedicated feeding equipment for each baby (do not share between babies).
-
Clean promptly after each feed — dried milk is harder to remove and grows bacteria.
2. Cleaning Steps
Step 1: Disassemble
-
Take apart bottles, nipples, and caps fully.
-
Rinse with cool water to remove milk.
Step 2: Wash
-
Use hot, soapy water and a clean bottle brush (not used for anything else).
-
Scrub inside bottles, nipples, and lids thoroughly.
-
Rinse well under running water to remove soap.
Step 3: Sterilize
-
Boiling Method (Low-Resource Friendly):
-
Place bottles, nipples, lids in a pot of water.
-
Boil for at least 5 minutes.
-
-
Steam Sterilizer (if available): Follow manufacturer instructions.
-
Chemical Sterilization (when boiling not possible): Use chlorine solution (WHO-recommended strength), soak for recommended time, then rinse with safe water.
Step 4: Dry and Store
-
Place bottles and parts on a clean towel or drying rack in an area free from dust.
-
Do not wipe inside with cloths — they may carry germs.
-
Store in a clean, covered container until use.
3. Storage Containers for Breast Milk
-
Use glass jars or food-grade plastic containers with tight lids.
-
Ensure containers are washed, sterilized, and air-dried before use.
-
Avoid cracked bottles or scratched containers — bacteria can hide in crevices.
4. Low-Resource Adaptations
-
If no bottle brush, use a clean dedicated cloth but boil afterward.
-
If no sterilizer, boiling is the safest and most widely available method.
-
Clay pots with lids or covered baskets can protect clean bottles from dust and flies.
5. Common Mistakes to Avoid
-
Rinsing only, without soap or boiling.
-
Using the same brush for dishes and bottles.
-
Leaving bottles wet in dirty kitchens.
-
Storing milk in used soda bottles or non-food-safe containers.
End of Lecture Quiz
Q1. What is the minimum boiling time to sterilize bottles and nipples?
A. 1 minute
B. 3 minutes
C. 5 minutes
D. 10 seconds
Answer: C. 5 minutes
Rationale: At least 5 minutes of boiling effectively kills bacteria and viruses.
Q2. True or False: Wiping bottles with a kitchen towel after washing is recommended.
Answer: False
Rationale: Towels may contain germs; bottles should air-dry instead.
Q3. Which of the following is acceptable for low-resource sterilization?
A. Boiling in clean water
B. Chlorine solution soak (correct strength)
C. Leaving in the sun for an hour
D. Both A and B
Answer: D. Both A and B
Rationale: Both boiling and chlorine sterilization are WHO-approved methods; sunlight alone is not enough.
