Some common traits of bad powdered milk are discoloration (it will begin to have a yellowish tint) and an odor. If an odor or discoloration appear in your powdered milk, then it should be discarded.
Expired baby formula.
Unopened cans of formula generally last a year—and this is the one food you don't want to serve past its use by date. It has nothing to do with food safety, but beyond that use by date, the nutrients in the formula will start to degrade, Chapman says.Tanzi, when powder blush expires, all that really happens is that it will "become hard and have a poor application." Even French admits to using certain powder products past their expiration date as long as they don't have "water, oils, or humectants that provide the preferred moist environment where germs and bacteria
Infant Formula Expiration Date
| Unopened in Pantry | Opened in Fridge |
|---|
| Infant/Baby Formula Liquid lasts until | use by date | 24 Hours once opened (or Manufacturer Instructions) |
| Infant/Baby Formula Powder lasts until | use by date | 24 Hours once mixed (or Manufacturer Instructions) |
Formula that's been prepared should be consumed or stored in the refrigerator within 1 hour. If it has been at room temperature for more than 1 hour, throw it away. And if your baby doesn't drink all the formula in the bottle, throw away the unused portion — do not save it for later.
The 1 hour rule applies to BM or formula that the baby has already touched. If the baby drinks from a bottle, their saliva causes bacteria to get into it. You can store unused BM and formula in your fridge for way longer.
Use product within one month. Once mixed, feed immediately or refrigerate in a sealed container, and use within 24 hours. See the label for specific instructions. Do not leave prepared formula at room temperature.
Because babies go through formula so quickly, you'll likely empty a container of powdered formula long before it hits its expiration date. But these containers do eventually expire, which could be an issue if you buy your formula in bulk quantities. Most formula containers are good for at least a year.
Use by dates are about safety
Foods can be eaten until the use by date but not after. You will see use by dates on food that goes off quickly, such as meat products or ready-to-eat salads. For the use by date to be a valid guide, you must carefully follow storage instructions.Food is still ok to eat even after the expiration date — here's for how long. The INSIDER Summary: It's hard to tell how long your food if good for once the expiration date has passed, plus each food is different. Dairy lasts one to two weeks, eggs last almost two weeks, and grains last a year after their sell-by.

It does not "go bad" but with increased openings and closings of a containter there is increased risk of exposure to foreign matter and moisture.
Formula that's been prepared should be consumed or stored in the refrigerator within 1 hour. If it has been at room temperature for more than 1 hour, throw it away. And if your baby doesn't drink all the formula in the bottle, throw away the unused portion — do not save it for later.
Ready-to-use formula is the most convenient type of formula. It's rich and thick, and you don't need to add any water to it before feeding. It's less likely to constipate babies than powder formula is, Dr. Shu says.
Because powdered formula is not sterile, babies under two months of age, or those who were born prematurely and not yet two months past their expected due date, and babies who have a compromised immune system should only be given concentrated liquid or ready-to-serve formula.
Formula that's been prepared should be consumed or stored in the refrigerator within 1 hour. If it has been at room temperature for more than 1 hour, throw it away. And if your baby doesn't drink all the formula in the bottle, throw away the unused portion — do not save it for later.
Reusing expressed breast milk
If your baby doesn't finish a bottle of freshly pumped or refrigerated milk, you can offer it to the baby again within two hours. Some mothers choose to leave the milk at room temperature and others prefer to refrigerate and rewarm. Either is fine.You check the date on the label, and it's already over a year past that date. Does powdered milk go bad? It's only powder, so you expect that it might be still okay to use it. But at the same time, you don't want to risk food poisoning for no reason.
Shelf Life for Powdered Milk
Powdered milk can go bad, but it takes awhile. Most manufacturers recommend using powdered milk (also known as dried milk) within 18 months, but this is really just a "best by" date. According to the USDA, powdered milk can be stored indefinitely.When unopened and in it's original form, powdered milk is good forever. But once opened and mixed with water, it needs to be used within 4–5 days. However, if you're talking about powdered baby formula, it will last about 2 hours at room temperature and should not be kept past a day or so in the fridge.
A prepared (but untouched) bottle of formula can be stored in the back of the fridge for 24 hours. Opened containers of ready-to-feed and liquid concentrate formulas are good for 48 hours. Powdered formula should be used within one month of opening the can or tub. Your fridge should be at 4°C or 40° F.
Similar to raw milk, powdered milk is loaded with nutrients; it is a good source of essential minerals and vitamins such as magnesium, calcium, zinc, potassium as well as vitamins A, D, E and K. During the evaporation process, it is ensured that these beneficial nutrients are not lost.
You could theoretically freeze your milk for up to three months, but it'll turn lumpy and yellow and yucky looking (though it's still safe to drink). The accepted rule of thumb is that if you're properly refrigerating it, your carton of whole milk's expiration date is five days after the "sell-by" date.
For example, if your recipe calls for 2 cups of liquid milk, (2 cups divided by 8) use 1/4 cup of regular powdered milk and two cups of water. Regular powdered milk doesn't mix easily in water.
