Explicit INNER JOINs are easier to read, easier to debug, and since 5.0.12 always preferable in MySQL for reasons given at http://dev.mysql.com/doc/refman/5.1/en/join.html (look for '5.0.12').
SELECT category.name, page.name, content.title, content.body FROM category INNER JOIN content USING (category_id) INNER JOIN page USING (page_id) WHERE category.id = 1 ORDER BY content.order_id ASC LIMIT 0 , 30 PB -- No virus found in this outgoing message.
