Food safety is the most overlooked aspect of meal prep. Improperly stored food goes bad within days, wasting money and potentially causing food poisoning. Following basic food safety principles keeps your prepped meals fresh for the full week.
Refrigeration guidelines: most cooked foods (chicken, beef, rice, cooked vegetables) last 4-5 days in the refrigerator at or below 4掳C. Never leave cooked food at room temperature for more than 2 hours. Cool food before refrigerating - hot food in closed containers raises the refrigerator temperature and creates condensation that accelerates spoilage. Always refrigerate meals individually in sealed containers.
Freezing extends storage significantly. Batch-cooked soups, stews, curries, and bolognese freeze for 3-6 months without quality loss. Portion and freeze meals you won't eat within 4 days. Label with date and contents. Defrost overnight in the refrigerator rather than at room temperature. Foods that don't freeze well: salad greens, cut raw tomatoes, cucumber, avocado, cooked pasta (texture degrades), and dairy-based sauces. Plan your weekly menu with this in mind: day 1-4 eat from the fridge, day 5-6 pull meals from the freezer. Rotate your freezer stock consistently and you'll always have a backup supply for weeks when meal prep doesn't happen.
