You have already been pointed to a couple of different references, but
most of those cover specific food groups, not brands of the same group.
It is possible to test just about anything, including milk and meat,
for dioxin. It is done all the time. However, the testing is
generally expensive. A dioxin/furan analysis for a single sample of
milk will run between $1000 to $2500 depending on the laboratory doing
the analysis and how quickly you want the results. Most of this
expense is a result of the cost of the equipment needed to run the
analysis, a high-resolution gas chromatograph and mass spectrometer,
the extraction process necessary to get a sample, and the technical
expertise needed to the do all this. Very few labs in the United
States test routinely for dioxins; those that do generally have a large
backlog of work (two to three weeks worth).
A problem that may impact your results is that different brands of milk
get their milk from a large number of different areas or farms. So the
same brand of milk may have widely varying concentrations of
dioxin/furans depending on where in the state or country it came from.
