I suggest spraying the packages with hydrogen peroxide before opening them.

The contents need to be sterile as well.

If the outside of the packages is contaminated, I’d guess the insides could be as well although I do realize that the outsides are more exposed to stuff so it is a good idea.

I’m thinking of stocking up on clorox and a spray bottle.

Hydrogen peroxide does jack against virus and is not very effective against bacteria. The foaming action is moderately useful as a wound cleaning agent .

Common household bleach is in the 3-8% range of sodium hyperchlorite. The medicos are using 10%+ solutions for decontamination. Those concentrations are available, just not at your neighbor grocery.
