Honey is not considered healthy if it has not been pasteurized because it contains bacteria which cause illnesses such as typhoid fever (paratyphoid), dysentery (enteric colitis), or other gastrointestinal diseases caused by salmonella bacteria which were not killed by pasteurization (inadequate killing) because they are present at low levels within raw honey (at times called “raw” honey). These diseases are dangerous enough that honey producers recommend consuming only UMF raw honey with at least 1-5 rating because these are usually free from such bacteria; if you find any higher rated honey on sale which doesn’t have any pasteurization process just ask for pasteurization certificate so that you know how much safe is your product when purchased online but make sure you do not trust online stores who doesn't show their certification proofs as they usually hide them from customers .
