Expired sweetened condensed milk can pose a risk of spoilage. Signs of spoilage include changes in color, texture, and smell. The consumption of spoiled sweetened condensed milk could result in foodborne illnesses, presenting symptoms such as nausea, vomiting, or diarrhea. Users should exercise caution and thoroughly inspect the product if it is past its expiration date, taking note of any indicators of spoilage before considering its use.
Understanding Sweetened Condensed Milk
Sweetened condensed milk is a dairy product whose characteristics and longevity are shaped by its unique composition and the way it's processed and stored.
Composition and Types
Sweetened condensed milk is created by removing most of the water from cow's milk and adding sugar. Compositionally, it is approximately 40-45% sugar, which not only adds sweetness but also acts as a preservative, enhancing its shelf life. There’s a distinct difference between sweetened condensed milk and its unsweetened counterpart, evaporated milk, which does not contain added sugar.
Shelf Life and Expiration Date
Typically, factory-sealed cans of sweetened condensed milk have a shelf life of one year past the printed expiration date. Both the sugar content and the hermetic sealing of cans are crucial for this extended shelf life. Once opened, the shelf life diminishes significantly, and it should be used within a few days. While it can endure past the expiration date when unopened, it's not recommended to use sweetened condensed milk if it shows signs of spoilage such as an off smell, color change, or the presence of mold.
Spoilage Indicators
When assessing the safety of using sweetened condensed milk, it's crucial to recognize the signs of spoilage. These signs can present themselves visibly, olfactorily, or texturally.
Visual Cues
Detecting changes in the color of sweetened condensed milk is a reliable way to identify spoilage. The product typically has a creamy white to light yellow hue. If there is discoloration such as a deep yellow or brown tint, or if you observe mold growth, the milk should definitely not be consumed.
Normal color: Creamy white to light yellow
Spoilage: Deep yellow, brown, presence of mold
Changes in Smell
A fresh can of sweetened condensed milk should have a sweet and pleasant smell. If the milk has gone bad, it will exhibit an odor that is off-putting and rancid. This olfactory change is often a clear indicator of spoilage. Another tell-tale sign is when the smell is noticeably sour.
Fresh smell: Sweet, mild
Spoilage: Rancid, sour
Texture Alterations
The texture and consistency of sweetened condensed milk should be thick and smooth. If the milk becomes lumpy or exhibits a watery separation, this signifies a breakdown in the product's texture. Furthermore, a curdled consistency is a strong sign that the condensed milk should not be used.
Normal texture: Thick, smooth
Spoilage: Lumpy, watery separation, curdled consistency
Health and Safety Considerations
When considering the use of sweetened condensed milk beyond its expiration date, it's important to understand the potential health and safety implications. Consuming expired products can lead to health risks, particularly when it comes to dairy items such as sweetened condensed milk.

Best By Date: This date indicates when the manufacturer believes the product will be at its peak quality. It is not a safety-related date. Sweetened condensed milk with a "best by" date may still be safe to consume after the date has passed, but its quality — including taste and texture — might not be optimal.
Expiration Date: Unlike a "best by" date, the expiration date is more closely related to food safety. Consuming products after the expiration date has a higher risk, particularly with perishable items. For canned condensed milk, using the product after the expiration date can result in spoilage and potential foodborne illness.
Understanding Food Labeling
Food labels are regulatory elements designed to inform consumers about the contents and safety of food. When it comes to sweetened condensed milk, the labels will often include both a best by date and an expiration date.
Best By Date: Typically placed on the can by the manufacturer.
Expiration Date: May also be referred to as "use by" date signaling the end of the estimated period of maximum quality as determined by the manufacturer.
Canned Condensed Milk: Knowing the distinction between these dates is particularly important for products like sweetened condensed milk, which can have a long shelf life due to the canning process. The high sugar content also acts as a preservative to extend the product's shelf life.
Food safety should always be a priority, and these labels are tools to help gauge the quality and safety of food products. However, they are not infallible predictors. Consumers should consider both the labeled dates and the condition of the product before use.
