Is American Cheese the top selling cheese in 1998 according to Dairy Association?

I do not have access to real-time information, including specific sales data from the Dairy Association for 1998. To find out whether American cheese was the top-selling cheese in 1998, you would need to:

* Contact the Dairy Association directly: They would be the most reliable source for this type of information.

* Search for industry reports or publications: Trade publications or market research firms may have data on cheese sales from that year.

* Consult historical sources: Look for archived data from cheese producers or industry publications from 1998.

Keep in mind that sales figures can vary based on how they are categorized (e.g., by type, weight, retail vs. wholesale).
