Colum with semicolon list

[thoand]

Hi
I have a colum that contains semicolon separeted lists

eg.:

|related_content

|1;34;5;4

I want do a select ala:
SELECT * FROM catalogue WHERE relatedContent LIKE '%5%'

The query above will offcourse work to some point, but if the colum contains eg. "4;55;2" this will also return set/s (55)

How can I do the query so I find only the rows which have "5" in related_content?
