After sterilizing baby bottles in a sterilizer, is it still possible for chemical residues to remain?
Hello Doctor, I am currently bottle-feeding my two-month-old baby with breast milk.
To keep track of the time I expressed the milk, I usually stick masking tape on the collection bottle and note the time with a ballpoint pen.
Today, I didn't notice that the tape was not removed before placing the bottle in the milk sterilizer.
I subsequently stored the breast milk and fed my baby (two feedings, 100ml each).
I would like to ask if the chemicals from the tape and ballpoint pen on the outside of the bottle could affect my baby due to the sterilization and drying process in the milk sterilizer? Or should I not be too concerned since the breast milk did not come into direct contact with these chemicals? Thank you for your assistance.

Dr. Xiao Kaiwen reply Pediatrics
The chemical substances contained in a small piece of tape and a few ballpoint pens should be in extremely trace amounts, and since there is no direct contact with breast milk, the possibility and quantity of contamination in breast milk are negligible, so there is no need for excessive concern.

When it comes to the safety of your breastfed baby in relation to chemical residues from tape and ink, there are several important factors to consider. First, let's break down the situation: you used tape and a permanent marker on the outside of a breast milk collection bottle, which was then sterilized in a bottle sterilizer. After this process, the bottle was used to store and feed your baby.
1. Chemical Composition: The tape and ink used in permanent markers typically contain various chemical compounds. For example, adhesive tapes may contain solvents, plasticizers, and other additives, while permanent markers often include pigments, solvents like toluene or xylene, and other chemicals. However, the amount of these chemicals that could potentially leach into the milk is minimal, especially since they are on the exterior of the bottle.
2. Sterilization Process: The sterilization process in a bottle sterilizer involves high temperatures and steam, which can help to break down and evaporate some of the volatile compounds present in the tape and ink. While it is unlikely that significant amounts of these chemicals would remain after sterilization, it is still a valid concern for parents.
3. Direct Contact with Milk: Since the chemical residues from the tape and ink are on the outside of the bottle and do not come into direct contact with the breast milk, the risk of contamination is significantly reduced. The milk itself is not likely to absorb harmful levels of these chemicals, especially if the bottle was properly cleaned and sterilized before use.
4. Health Risks: The potential health risks associated with exposure to small amounts of these chemicals are generally low, particularly in the context of brief exposure. Most studies indicate that the levels of exposure from incidental contact with such materials are unlikely to cause harm. However, it is always prudent to minimize exposure to any unnecessary chemicals, especially in infants.
5. Recommendations: If you are still concerned about the potential effects, it is advisable to monitor your baby for any unusual symptoms or reactions after feeding. If you notice anything concerning, consult your pediatrician for further evaluation. Additionally, consider using non-toxic, food-safe labeling options in the future, such as masking tape or labels specifically designed for food containers.
In summary, while there is a theoretical risk associated with chemical residues from tape and ink, the practical risk to your breastfed baby is minimal, especially given that the milk did not come into direct contact with these materials. It is always best to err on the side of caution, but in this case, you likely do not need to worry excessively. If you have ongoing concerns, discussing them with your pediatrician can provide peace of mind and tailored advice.
