it would be highly highly unlikely that you would get a food-borne parasite from a knife touching processed commercially-produced bacon based on what you described. parasitic infections are not treated with antibiotics.
can you get a parasite from having your knife touch uncooked bacon and then touching your food? . i accidentally used the same knife to open a bacon package and separate a slice of bacon and then used the same knife to slice open an avocado? can you get a parasite from this and should my husband and i see a doctor to get some sort of antibiotic?
