These labels are essential for ensuring food safety, preventing health risks, and empowering consumers to make informed choices about the products they purchase and consume.

Use-by dates on food labels indicate the last date a product is considered safe to consume. These dates are crucial for perishable items like dairy, meat, and ready-to-eat meals. Here's how to read and understand them: 1. **Format**: Use-by dates are typically presented in day/month/year format, though this can vary by country. For example, "Use by 12/10/2023" means the product should be consumed by October 12, 2023. 2. **Safety**: Consuming food past its use-by date can pose health risks, as the product may spoil or harbor harmful bacteria. Always prioritize safety and avoid eating foods that have surpassed this date. 3. **Storage**: Proper storage is essential to ensure the product remains safe until the use-by date. Follow any specific storage instructions on the label, such as refrigeration or freezing. 4. **Appearance and Smell**: Even before the use-by date, check the food's appearance and smell. If it looks or smells off, it's safer to discard it, regardless of the date. 5. **Exceptions**: Some products may still be safe shortly after the use-by date if stored correctly, but this is not guaranteed. Use discretion and consider the type of food and storage conditions. 6. **Regulations**: Different countries have varying regulations regarding use-by dates. Familiarize yourself with local guidelines to better understand how these dates are determined and enforced. 7. **Difference from Best-Before Dates**: Unlike use-by dates, best-before dates indicate quality rather than safety. Foods past their best-before date may lose flavor or texture but are not necessarily unsafe. By understanding and adhering to use-by dates, you can ensure food safety and reduce the risk of foodborne illnesses.

Use-by dates and best-before dates are both indicators of a product's shelf life, but they serve different purposes. Use-by dates are found on perishable items like dairy, meat, and ready-to-eat meals. They indicate the last date the product is considered safe to consume. Consuming products past this date can pose health risks due to potential bacterial growth. It is crucial to adhere to use-by dates for safety reasons. Best-before dates, on the other hand, are found on less perishable items like canned goods, pasta, and snacks. They indicate the period during which the product will remain at its optimal quality, such as taste and texture. Consuming products past this date is generally safe, but the quality may have diminished. In summary, use-by dates are about safety, while best-before dates are about quality.

To identify allergens on food labels, follow these steps: 1. **Look for Allergen Statements**: Most food labels have a "Contains" statement near the ingredient list, highlighting major allergens like milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soy. 2. **Check the Ingredient List**: Read through the entire ingredient list for any mention of allergens. Ingredients derived from allergens might be listed under different names, so familiarize yourself with alternative names (e.g., casein for milk, albumin for eggs). 3. **Advisory Statements**: Look for precautionary statements such as "may contain," "produced in a facility that also processes," or "made on shared equipment with." These indicate potential cross-contamination risks. 4. **Understand Allergen Labeling Laws**: In many countries, food manufacturers are required by law to clearly label the presence of major allergens. Familiarize yourself with local regulations to understand what must be disclosed. 5. **Identify Hidden Sources**: Some ingredients may not explicitly mention allergens but could be derived from them. For example, lecithin can be derived from soy, and malt extract might contain gluten. 6. **Be Aware of Non-Food Items**: Some non-food items like cosmetics or medications may also contain allergens, so check their labels if you have severe allergies. 7. **Contact Manufacturers**: If in doubt, contact the manufacturer for clarification on ingredients and potential cross-contamination. 8. **Use Technology**: Utilize apps and online resources that can scan barcodes and provide allergen information. 9. **Stay Updated**: Allergen labeling practices and regulations can change, so stay informed about any updates in food labeling laws. By carefully examining food labels and understanding labeling practices, you can effectively identify potential allergens and make safer food choices.

Food labels typically require the following information: 1. **Product Name**: The common or usual name of the food. 2. **Net Quantity**: The amount of food in the package, expressed in weight, volume, or count. 3. **Ingredients List**: All ingredients used in the product, listed in descending order by weight. 4. **Allergen Information**: Identification of common allergens such as milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, and soybeans. 5. **Nutrition Facts**: A panel that includes serving size, calories, and nutrient information such as total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrates, dietary fiber, sugars, protein, vitamins, and minerals. 6. **Manufacturer Information**: Name and address of the manufacturer, packer, or distributor. 7. **Country of Origin**: Where the product was made or processed. 8. **Expiration Date**: Best before or use-by date to indicate the product's shelf life. 9. **Storage Instructions**: Guidelines on how to store the product to maintain its quality and safety. 10. **Lot or Batch Number**: For traceability in case of recalls. 11. **Claims and Certifications**: Any health claims, organic certification, or other relevant certifications. 12. **Preparation Instructions**: If applicable, directions on how to prepare or cook the product.
