A number of . poultry producers have addressed the practice in advertising campaigns. In March 2009, West Coast poultry producer Foster Farms and their advertising agency Goodby, Silverstein & Partners launched a campaign centered on "Say No To Plumping." TV commercials in English and Spanish featured the long-running Foster “Imposters” discussing the effects of plumping.  The "Say No To Plumping" campaign won the 2010 Gold Effie Award in advertising.  Sanderson Farms previously ran an advertising campaign on TV and outdoor billboards drawing consumer attention to saltwater injected chicken. 
The difference I’ve found at my local markets is about a 10X hike in “Sodium”. No one said NAcl here, as in table salt ! Industry is using a
variety of chemicals, perhaps Sodium Nitrate to get chicken to hold the
extra water. This is linked to Heart disease, cancer and perhaps Type
2 Diabetes. Who knows what other toxins industry adds to increase their
profits, under the category of “Sodium”. Too bad that the USA is run by
lobbyists! and you can be fed all sorts of toxins to benefit global corporations. If anyone wants to help clean up Washington, they can run over a lobbyist.
