For this reason, it is important to carry out effective control throughout the entire production process. Therefore, the supplier, the manufacturer, the ship unit, the sales unit and also the consumer are responsible for food safety. Food safety and quality is regulated by applying food safety and quality programs in the bakery sector. Food contamination refers to the presence in food of harmful chemicals and microorganisms which can cause consumer illness. Contamination can occur directly
