The PR firm Ruder Finn [3] has lost the account working for the U.S. Tuna Foundation [4] to defend human consumption of canned tuna containing high levels of mercury. Burson-Marsteller [5] has landed the account. "Amid the transition, Burson is working to challenge a widely cited Consumer Reports study [6] published this month which found canned light tuna can contain higher levels of mercury than other tuna and could pose serious problems to an unborn child," O'Dwyer's reports. The foundation has also appointed Anne Forristall Luke, a former "principal at Washington, D.C. firm MGN and former public affairs practice head for Ketchum [7]," to head the organization.
