Pregnancy guidance
RecommendedIs Colby or Colby Jack cheese safe during pregnancy? Yes, when the label says it is made with pasteurized milk. CDC lists hard cheeses such as cheddar, when made with pasteurized milk, as safer choices and cheese made from raw milk as riskier; its chart does not name Colby, so check the label. CDC: safer food choices in pregnancy
FDA notes that some cheeses are not made with pasteurized milk, especially local or specialty ones. CDC lists unheated cheese sliced at a deli as riskier; heat deli-sliced Colby to 165°F or until steaming hot. FDA: dairy and eggs for moms-to-be
