What important document will a health investigator want to see in case of a complaint of food-borne illness? the contact information for the crisis management team the total sales receipts for the establishment the license of the food establishment the logs for temperature control

You did not show us the image of the burger, but i shall try to answer as best i can.  when purchasing food, always consider the ingredients as well as the person who prepared it. consider if they were hygienic people or not, in case the burger was infected with bacteria. no mortal should place an infected burger into their mouth.
