A federal magistrate in Florida has denied the plaintiffs’ request in multidistrict litigation challenging marketing claims that DHA Omega-3-fortified milk supports brain health to reconsider an earlier order excluding the testimony of their expert. In re Horizon Organic Milk Plus DHA Omega-3 Mktg. & Sales Practice Litig., MDL No. 2324 (U.S. Dist. Ct., S.D. Fla., order entered June 17, 2014). Details about the magistrate’s ruling excluding the plaintiffs’ expert appear in Issue 522 of this Update.

The magistrate rejected the plaintiffs’ arguments for their failure to raise them when the motion to exclude the evidence was before him and determined that an intervening U.S. Food and Drug Administration final nutrient content rule on DHA is not new evidence and does not address the ground on which the magistrate struck the expert—his failure to show how the studies on which he relied could be extrapolated to cover the broad class of product purchasers.
