Hi everyone, according to an article from optics.org entitled "Laser-etching promotes egg safety," "US consumers can now tell exactly how fresh the eggs in their refrigerator are thanks to tamper-proof expiry dates.

Eggs that are laser-etched with an expiry date and a code that traces the egg back to where it was packaged are now available in the US. Developed by US firm EggFusion, the laser system etches a permanent, easy-to-read and tamper-proof mark on the eggshell which allows consumers to see when the egg should be used by.

EggFusion uses a pulsed sealed carbon-dioxide laser to etch the eggshells. According to Roger Tye, EggFusion's VP of marketing and communications, the laser removes between 5 to 8% of the eggshell and the structural integrity of the shell in maintained. "The laser does not heat the egg so we are not cooking the inside in the process," he added."

Here is a picture of the laser-etched egg.

Cheers, :)
