my learning issues

i find something about product recall..the definition is: a request to return to the maker a batch or an entire production run of a product, usually due to the discovery of safety issues.

anyway, Recalls are not always easy to learn about, and companies do not always publicize a recall in an effort to limit the cost of replacing the product. thus, the recall information can be obtained from:
Grocery Stores (listings), Mailings, News (television/print), Internet, particularly consumer groups' websites.

there are certain steps to a product recall, and as a general, these are the steps:

1)Maker or dealer notifies the authorities responsible of their intention to recall a product. Consumer hotlines or other communication channels are established. The scope of the recall, that is, which serial numbers or batch numbers etc. are recalled, is often specified.

2)Product recall announcements are released on the respective government agency's website (if applicable), as well as in paid notices in the metropolitan daily newspapers. In some circumstances, heightened publicity will also result in news television reports advising of the recall.

3)When a consumer group learns of a recall it will also notify the public by various means.

4)Typically, the consumer is advised to return the goods, regardless of condition, to the seller for a full refund or modification.

5)Avenues for possible consumer compensation will vary depending on the specific laws governing consumer trade protection and the cause of recall.


Finally, Commonly Recalled Products are things causing harm or danger to the consumers, other defects diminishing functionality, and inadequate documentation (typically requires just re-shipment of documentation rather than a recall)
