Consumer Reports review of hot dogs finds so-called “nitrate-free” hot dogs are…not so much.

If you thought you were doing the right thing by selecting chicken or turkey franks or uncured dogs with no added nitrates, think again. Our tests found they did not all deserve a health halo. While three of the four regular poultry dogs we rated had 30 to 80 fewer calories than the average of beef and mixed meat dogs, the other poultry frank had as many calories as beef. And most had plenty of fat and sodium. While the three uncured franks might boast of “no added nitrates,” our testing found that Applegate Farms, Coleman Natural, and Whole Ranch contained nitrates and nitrites at levels comparable to many of the cured models.

Our analysis found that the nitrates and nitrites in all the hot dogs we tested were well below the maximum level for the additives established by the USDA. While a hot dog can be labeled uncured if no nitrates or nitrites have been added, that does not necessarily mean the product is free of them. The three uncured models we tested contained nitrites and nitrates because the compounds occur naturally in spices and other natural ingredients added during processing.
