What are the disadvantages of chemical sanitizers?

Chemical sanitizers can have several disadvantages, including potential health risks, such as skin irritation or respiratory issues for users. They may also leave harmful residues if not used correctly, posing risks to food safety. Additionally, some sanitizers can be less effective against certain pathogens or in the presence of organic matter, necessitating thorough cleaning beforehand. Finally, over-reliance on chemical sanitizers can lead to microbial resistance, reducing their effectiveness over time.
