Yes, Kraft Parmesan cheese should be refrigerated after opening. Like most dairy products, grated Parmesan cheese is susceptible to spoilage and bacterial growth if left at room temperature for extended periods.
Refrigeration helps slow down the growth of harmful bacteria and molds, preserving the quality and safety of the cheese. When properly stored in the refrigerator, grated Parmesan cheese can maintain its flavor and texture for a longer period.
To store it correctly, place the opened container or package of Kraft Parmesan cheese in the refrigerator in an airtight container or resealable bag. This will help prevent moisture and odors from affecting the cheese and keep it fresh for as long as possible.
Always follow the manufacturer's storage recommendations, as specific guidelines might be provided on the packaging. If the cheese develops an off smell, appearance, or texture, it's best to discard it to avoid any risk of foodborne illness.
