They didn’t follow the proper food safety and hygiene practices.

I’m sure youheard about the restaurant that made salsa with contaminated tomatoes. Many people got sick. Some people even died. They didn’t follow the proper food safety and hygiene practices. They apparently did not thoroughly wash the tomatoes that they used to make the salsa before they cut them up. By wshing raw fruits and vegetables before cutting into them, you reduce the risks of contamination like that. You avoid illnesses and deaths. Imagine knowing that you could have prevented illnesses and deaths just by doing your job properly. Skipping a step can cost people their lifes, and you could be held responsible.
