When you package ground beef with nitric oxide gas, it leaves behind more nitrite and nitrate chemicals than other gases like carbon monoxide or plain oxygen—and when you cook the meat, even more of these chemicals show up, maybe because the gas breaks apart inside the meat.

Assessment Explanation
The claim describes a mechanistic pathway involving chemical dissociation, which is plausible based on known chemistry of nitric oxide in meat systems. However, the word 'potentially' correctly signals uncertainty about the dissociation mechanism. Existing studies on modified atmosphere packaging and nitrosylmyoglobin breakdown support the trend of increased nitrite/nitrate, but direct evidence linking cooking-induced dissociation to measurable nitrite/nitrate increases is limited. The claim avoids overstatement by using 'potentially' and comparative language, making 'probability' the most appropriate verb strength.
More Accurate Statement
“Nitric oxide-modified-atmosphere packaging is associated with higher residual nitrite and nitrate levels in ground beef compared to carbon monoxide and high-oxygen packaging, and levels may increase further after cooking, possibly due to dissociation of bound nitric oxide into nitrite and nitrate.”

Evidence from Studies
Supporting (1)
The study found that when ground beef is packed with nitric oxide gas, it ends up with more nitrite and nitrate left in it than when packed with other gases — and these chemicals can increase even more after cooking, which matches what the claim says.
