Advanced GREP technique ?

I've been doing quite a number of bash scripts in these last months of using linux. In most of them I make use of the 'grep' command. However I've encountered a situation where my basic knowledge of grep cannot help me that much. Suppose I have a table show below:

1,USA,aaa
2,USAX,bbb
3,USAY,ccc

What if I want to grep for the USA only? doing a normal grep "USA" will give you all the three entries, whereas doing grep -o "USA" will display nothing because the pattern "USA" is not alone....

Is there a way to go around it??

thanks I have just figured it just at this moment. By the way, it even works without the backslash.
