What is the problem of finding E.coli and Clostridium perfringens in the feed after pelleting? Is it the simple presence or concentration of these bacterias? The reason for my question is that, in the gut of healthy birds we found concentrations of up to 10E4 or even higher of E. coli and C. perfringens without causing any problems. According to Disease of Poultry 14th Ed. 2020, the presence of E. coli in the lower intestine tract is benefical, aiding in growth, development and inhibiting other bacteria like Salmonella.
Don't you think that sometimes the problem is not the microbiology of food, but the disruption of the animals' microbiota?

@Paulo Martins , the presence of E. Coli or other pathogens in finished feed indicates that a critical control step, pelleting, had failed or that the feed has become contaminated after the pellet mills indicating poor quality control of the manufacturing process. You are correct that the birds intestine does contain these bacteria and receives these bacteria from many different sources, however the feed should not contribute to the bacteria load in the intestine.
Feed mills with excellent quality procedures produce pathogen negative feeds with a total plate count of 1,000 to 20,000 total colony forming units per gram of feed at feed load out.
