4．　　If you bought some candy months ago but never ate it, how can you tell whether it's still eatable?The easiest way is to check the" expiration date (EXP)" printed on the cover. If that date has already passed, you may throw the candy away. But is that really necessary?
　　According to a new report from the NRDC, tons of food is wasted each year, largely because people don't fully understand what expiration dates, or "use﹣by dates", actually mean, so they think the food is not safe to eat.
　　Food dating was introduced in 1975 because customers wanted more information about the things that they were eating. When they first showed up, use﹣by dates only showed freshness because producers wanted their products to be tasted in their best conditions.
　　However, most customers mistakenly believed that use﹣by dates showed how safe the food was. But the truth is that these dates have nothing to do with the danger of food poisoning(中毒). Eggs, for example, can still be eaten three to five weeks after being bought, even though the use﹣by dates is much earlier. When their use﹣by dates pass, cookies may lose their crunch(松脆的口感), but they are not harmful.
　　"It's an unclear subject, the difference between food quality and food safety, "said Jane Roberts from a US food testing company. "Even the workmates in the food factory are not sure about it. This is why the use﹣by dates must be printed on the covers of products. We hope it can help customers understand the information so that they won't waste a lot of food. "
　　But this won't be a mistake that is easy to correct, because people have believed it for so long. Another problem is that the quality levels of different foods change differently. Some are still eatable long after their use﹣by date while others are not.
　　As a result, food factory officials are not thinking of changing the use﹣by dates to a date which can show when the food is to be thrown away.
