I built one of the trade promotion management (TPM) tools used in that space and had to deal with these companies daily for the last decade.

There are absolutely a bunch of acquisitions/ consolidation in that food distribution space, but there are still hundreds of different distributors just in the US. However, most volume does flow through the largest distributors.

For example, I had to build a specific feature to merge distributors after an acquisition happens in the industry, to make the product work properly because that's such a common occurrence. Had the same type of feature for manufacturers (my customers) also, because they kept buying each other.
