Reduce moisture loss
Keep contaminants from entering through the shell pores
When you rinse eggs under water, especially before storage or cooking, you can actually remove or weaken this protective layer.
So instead of making eggs safer, rinsing can sometimes do the opposite.
Why Some People Think Eggs Should Be Rinsed
The habit of rinsing eggs usually comes from older kitchen traditions or regional practices. Many people learned it from parents or grandparents who believed:
Eggs might carry dirt or bacteria on the shell
Washing removes anything harmful
Clean-looking eggs are safer to eat
In earlier decades, especially in home kitchens without strict food regulation systems, rinsing seemed like a logical precaution.
However, modern food production standards have changed significantly.
Today, commercially produced eggs in many countries are:
Washed and sanitized at processing facilities
Inspected for quality control
Stored under regulated conditions
Because of this, the need for additional rinsing at home is greatly reduced—and often discouraged.
What Actually Happens When You Rinse Eggs
Rinsing eggs under water can introduce a few unintended risks:
1. Loss of the Natural Barrier
Zoals eerder vermeld, hebben eieren een beschermende laag. Water kan deze laag verzwakken of verwijderen, waardoor bacteriën gemakkelijker de schaal kunnen binnendringen.
