As previously stated, while the white lumps in Spam are typically harmless solidified fat in Spam, there are circumstances in which you should discard the product entirely.
Be aware of the following warning signs:
• A bulging or warped can
• Liquid leaking from the can prior to opening
• Deep rusting or severe denting along the seams of the can
• An unpleasant or sour-smelling odor after opening
• Sliminess or an abnormal discolored appearance
If any of these signs are present, do not debate this further. Can safety largely depends upon maintaining the seal of the container. When the seal fails, bacterial growth occurs.
However, if none of these signs are apparent and everything looks, smells, and tastes normal except for the white lumps in Spam, it is safe to consume.
Something I have learned firsthand when it comes to food safety is this: when determining the quality of packaged food, the smell and overall condition of the packaging are much more relevant than the aesthetics of the product.
How They Dissolve When You Cook Them
While frying the Spam for the first time, I observed that the firm white chunks began to dissolve into the meat. What I realized was that fat changes states due to heat.
When pork fat is cold and solidified, it is white. When heated, it becomes liquid and translucent. When fat dissolves during cooking, it is absorbed into the surrounding meat, creating a juicier texture and crispy exterior on the Spam.
When I fried several slices of Spam, the white lumps simply dissolved into the meat. That alone gave me enough confidence to realize I was not dealing with anything harmful.
Therefore, when you view white lumps in Spam and panic, breathe deeply. In nearly all normal circumstances, you are merely observing solidified fat in Spam performing its function.
Check the can. Check the smell of the product. Examine for abnormal coloration or texture compared to normal fat. If everything appears normal, you have no reason to panic.
For me, when I observe those white specks in Spam today, I am confident in knowing exactly what I’m looking at. Not mold. Not contamination. Just part of what is inside of Spam and part of why it tastes so good.
