How can i prevent foodborne illness with colloidal silver?

Odd question: Foodborne illness is from insufficiently cooked meat as well as vegetable sources. There is no evidence that colloidal silver will protect you even though it has been in use as an antibiotic for years and was banned by the fda.

You can't: Colloidal silver is a much-hyped, cynical health fraud. It has some use as a topical skin antibiotic in extreme situations such as burns. The promotion has caused deaths from brain damage and has turned plenty of people a permanent blue. Follow evidence-based, common-sense guidelines to prevent foodborne illness instead, and good luck.
