Silver can sterilize. As long as every liter of water contains one milligram of 50 million silver ions, most bacteria in the water can be killed. Its principle is that silver can form positively charged ions in water, adsorb bacteria in water and gradually enter bacteria, so that its catalyst-anchoring system is deactivated, and bacteria lose their metabolic ability and die. Therefore, it is good to use silver to make dishes and chopsticks in daily life.

So you can cook.
