Here is a link I found on the mold. It also states Purinas response to this. http://www.handicappedpets.com/news/beneful.html . Take it for what its worth...
Lady human- no offense but considering that dogs eat only thing, twice a day, day after day- if there was any problem with the only thing they ate 365 days a year- I would rather know. Several foods have had recalls in the past- Nutro, Diamond, Natures Receipe etc. I would trust going back to a food if the company said " there was a problem with this batch number so-in-so " then ignoring IF there was a problem. It took several years before Iams and Eukenuba removed the ethoxyquin from their foods- and others followed suit just as an example. Vitamin E has also had recalls for rancid E.
I add ( for the total 4 large dogs) 1/2 cup total of Solid gold crushed in the food processor to the veggie, egg, and liver mixture. The only reason I do this is not to just soak up the egg- its actually so the dogs are use to this food if I had to feed it for a few days from power loss on this mountain. We all take our own precautions- and while this could be a hoax- considering this is the only form of nutrition someone feeds this dog- I would not take any chances.
