Food safety refers to the procedure that includes the preparation as well as proper storage of food items that help to reduce the existence of physical or biological contamination.

The increase in dependency of people on packed food items has led to the growth of various airborne or food or foodborne diseases (Accorsi and et.al., 2017).
I see it’s been a while since you’ve posted, and this is a strong point to highlight. Food safety often gets overlooked, especially with the growing reliance on packaged foods.
I used to assume sealed = safe, but that’s not always true. Seeing discussions like https://www.reddit.com/r/mealprep/comments/1p5evjd/today_i_found_out_frive_has_a_hygiene_rating_of_1/ made me pay more attention to who’s actually taking cleanliness seriously. Some meal prep services like Frive stick to proper hygiene, which honestly gives more peace of mind than random packaged stuff from a shelf.
