Are microplastics in sugar a concern?
Use caution, but keep this in perspective. A 2026 Journal of Hazardous Materials study found microplastics in refined sugar from the Italian market. That does not make sugar the biggest source in your kitchen. It does make glass storage a practical next step for dry goods.
Short answer
Yes, researchers have found microplastics in refined sugar. That does not prove sugar is the biggest source in your kitchen.
The useful step is simple: store sugar and other dry goods in glass when you can.
Why this matters
Sugar is a dry food that can pass through growing, processing, packaging, shipping, and home storage before it reaches your pantry.
Microplastic research is still growing. The practical goal is to reduce plastic contact where the swap is easy.
What the research says
A 2026 Journal of Hazardous Materials study tested white sugar from the Italian market. The researchers found small microplastic particles, mostly in the 5 to 10 micrometer range. PVC was the most common polymer found, followed by PE, PS, PP, and PET.
Another 2026 Journal of Hazardous Materials review looked across food types and found that microplastics have been reported in many foods and drinks, not only sugar.
What to do instead
Keep sugar, flour, rice, and other dry goods in clean glass jars with tight lids. Avoid pouring hot food into plastic containers.
For a pantry swap, browse glass storage jars.
