Cronobacter is a common germ found in many places—the yard, kitchen, and living room, just to name a few. It can get into our homes from our shoes or hands and can spread as we touch countertops and utensils. Cronobacter can also be found in dry foods like powdered infant formula and can contaminate breast pumps and other dry surfaces.
Although Cronobacter infection is rare, it can be life-threatening. It’s most dangerous for babies less than 2 months old, babies born prematurely, and babies who have weakened immune systems.
Breastfeed if you can. Even if you can only breastfeed for a few months, it can help protect your baby from getting sick.
If your baby is at high-risk, and you cannot breastfeed, the Centers for Disease Control and Prevention (CDC) recommends using ready-to-feed infant formula. WIC may require a prescription from your healthcare provider to allow ready-to-feed formula. Contact WIC to learn more.
Safely prepare formula and store breastmilk. No matter your baby’s age, it’s important to make food safety a priority:
Always wash hands with soap and water for 20 seconds before preparing stored breast milk or formula. If water isn’t available, use hand sanitizer with at least 60% alcohol.
Clean and sanitize countertops and work surfaces that may touch bottles, nipples, or breast pump parts. Use a disinfecting wipe or paper towel with a cleaning solution.
Clean and sanitize nipples, rings, bottles, and breast pump parts in the dishwasher or a clean wash basin after every feeding. Don’t wash in the kitchen sink as it can have germs. Let everything air dry and store in a clean, protected area.
When shopping for formula, make sure it will not expire soon, and is not dented or rusted. Store unopened formula in a cool place. If you use powdered formula:
If preparing powdered or concentrated formula, boil the water you’ll use and let it cool for 5 minutes before mixing with the formula. If there is a “do not boil” alert, or you cannot boil the water, use bottled water instead. Follow the formula label instructions for mixing. Always measure the water first, and then add the formula. Before offering to your baby, let it cool so it doesn’t burn their mouth.
Sanitizing is an extra step after washing bottles, nipples, and pumps to make sure all germs are killed. Feeding items should be sanitized once daily for high-risk babies. Also sanitize the things you use to wash feeding items like the bottle brush and basin.
Wash equipment in the dishwasher with a heat dry or sanitize setting, or boil items in a covered pot of water for 5 minutes. Remove items with clean tongs and cool on a clean cloth or paper towel.
If boiling or using a dishwasher is not an option, use a diluted bleach solution. In a clean basin (only used for washing infant feeding items) mix 2 teaspoons of unscented bleach with 1 gallon of water (16 cups) or 1 teaspoon with 8 cups of water. Put all items underwater and soak for at least 2 minutes. Squeeze the solution through nipple holes. Remove with clean tongs and place on a clean, unused dish towel or paper towel in an area protected from dust and dirt. Air dry thoroughly before storing. There is no need to rinse the items or use a towel to dry.
