Which of the following describes the best way an individual can prevent food-borne illnesses at home?

draft guidelines for the handling of food in restaurants and stores
create legislation to limit pathogen levels in food manufacturing
improve sanitation during the packaging process of food production
avoid cross-contamination during food preparation and storage

The correct answer is actually "Avoid cross-contamination during food preparation and storage" I thought the other answer was wrong but i put it anyways because of all the thanks and to see and just checked my answers and got it wrong when i put "Improve sanitation during the packaging process of food production " if you really think about that it doesnt make sense because were not producing and packaging our own food at home unless you live on a homestead lol it would make much more sense to wash your hands and utensils to avoid cross contamination, i know this is old but here for all the people like me lol

Avoid cross contamination during food preparation & storage

i have to report this, it doesn't relate to biology
