Decoding the Dates: 'Best Before' vs. 'Use By'
In India, the Food Safety and Standards Authority of India (FSSAI) sets the rules for food labels to ensure consumers get clear information. The two most common dates you'll see are 'Best Before' and 'Use By' (or 'Expiry Date'), and they mean very different
things. 'Best Before' is all about quality. It tells you how long the food will retain its optimal flavour, texture, and nutritional value. After this date, the food might lose some of its freshness but is often still perfectly safe to eat. On the other hand, 'Use By' or 'Expiry Date' is a safety deadline. This is typically found on perishable items like meat, dairy products, and ready-to-eat meals. Consuming a product after this date could be harmful to your health and is not recommended.
The Critical Difference: Quality vs. Safety
The core distinction to remember is that 'Best Before' relates to the peak quality of a food item, while 'Use By' relates to its safety. Food can be safe to eat even if it’s past its 'Best Before' date, though it might not taste as good as it once did. Think of a packet of biscuits that might become less crisp or a spice that loses some of its aroma. In contrast, you should strictly adhere to the 'Use By' date. After this date, harmful bacteria can grow in perishable foods, even if they look and smell fine, posing a risk of foodborne illness. The only major exception where a quality date is also a safety date is for infant formula, which has a mandatory 'Use By' date to ensure it contains the right amount of nutrients.
Who Decides on the Date?
Interestingly, there isn't a single central agency that tests and assigns every date on every product. Instead, it is the manufacturer's responsibility to determine the shelf life. They conduct tests to see how long a product remains at its best quality and safety under specific conditions. This involves considering factors like the ingredients used, the manufacturing process, the type of packaging, and how the food will be stored during distribution and in the store. Some companies even perform 'accelerated' tests where they manipulate the environment, like raising the temperature, to see how quickly the food deteriorates and then use that data to predict its normal shelf life. This is why you see such a wide variety of dates, as each product's journey from factory to shelf is unique.
Beyond the Label: Trust Your Senses
While dates are a useful guide, they aren't foolproof. Your best tools for judging food safety are often your own senses. Before you eat something, especially if it's near or past its printed date, give it a quick inspection. Look for any changes in colour, such as meat that has darkened, or the appearance of mould. Smell the food for any off, sour, or unpleasant odours. Check the texture; for example, meat that feels slimy or vegetables that have gone soft and mushy may be spoiled. If a can is bulging, dented at the seam, or leaking, you should discard it immediately. These signs are reliable indicators that a food has gone bad, regardless of what the date on the label says.
The Power of Proper Storage
How you store your food has a massive impact on its shelf life, often more so than the printed date. Food date labels assume the product has been handled and stored correctly every step of the way. To prevent bacteria from growing, your refrigerator should be set at 4°C (40°F) or below. Perishable items like raw meat, poultry, and leftovers should never be left at room temperature for more than two hours. Proper separation is also key; always use different cutting boards for raw meats and vegetables to avoid cross-contamination. Storing foods in airtight containers and following any specific storage instructions on the package can help maintain quality and safety for longer, making the printed date a more flexible guideline.
