Salmonella has been implicated in some renal and liver failures in dogs, although prevailing buzz is that Salmonella is killed by doggy digestive tracts if the dogs are healthy enough. That being said, kibble is usually fed day after day, with no change of diet as there would be in a wild dog. Here is one link on liver failure:

Jerky treats also have been implicated in organ failure in pets eating them.
A food that looks that bad could probably cause serious issues long term on it's own merit without salmonella. The digestible protein is probably way low and lacking in some amino acids. People shouldn't have dogs if they can't feed them properly.
