1. Understanding Food Expiration Dates: More Than Just a Deadline
Food expiration dates are often misunderstood and can lead to unnecessary food waste. But what happens if you eat expired packaged food? The answer is nuanced. These dates primarily indicate quality rather than safety. Let’s explore the different types of dates and what they really mean.
1.1 The Nuances of “Best By,” “Sell By,” and “Use By” Dates
It’s crucial to differentiate between “Best By,” “Sell By,” and “Use By” dates.
- Best By: This indicates when the product will have the best flavor or quality, as Janilyn Hutchings, a food scientist at StateFoodSafety, explains. Foods past this date might not taste as fresh but are generally safe to consume if there are no signs of spoilage.
- Sell By: This date is for retailers, indicating how long the product should be displayed for sale. The USDA clarifies that food is typically safe to eat even after this date.
- Use By: This is the last date the product will be at its peak quality. For infant formula, this date is critical and regulated, ensuring nutritional content. However, for most other foods, it’s still about quality, not safety.
1.2 Expiration Dates: Quality vs. Safety
Jennifer Kaplan, a former food systems instructor at the Culinary Institute of America, notes that expiration dates are “a manufacturer’s vague estimate of when the product is at its ‘freshest.'” Many foods can still be safe to eat days, weeks, or even months after these dates.

1.3 The Role of Manufacturers in Setting Expiration Dates
Manufacturers determine expiration dates based on their assessment of product quality over time. This assessment considers factors like taste, texture, and appearance. It’s not necessarily a reflection of when the food becomes unsafe to eat.
1.4 Legal Regulations on Expiration Dates
Interestingly, except for infant formula, expiration dates are not required or regulated by law on most food products. This means manufacturers have considerable leeway in setting these dates.
2. The Real Risks: What Happens When You Eat Expired Food?
So, what happens if you eat expired packaged food? While many foods remain safe to eat past their expiration dates, there are potential risks to consider.
2.1 Potential Health Risks of Consuming Expired Food
Consuming expired food can lead to several health issues, primarily due to the growth of bacteria and other microorganisms.
