As of May 11, at least 15 people in nine states and one person in Canada had been confirmed infected with Salmonella from contact with the contaminated dry dog food or from contact with a pet that had eaten the tainted product, according to the Centers for Disease Control and Prevention (CDC).

The report states that Diamond was using cardboard and duct tape on some of its equipment and that there were damaged paddles on the conveyor. The inspectors also noted that some surfaces at the facility were encrusted with food residues.

FDA inspectors specifically listed these four observations:


All reasonable precautions are not taken to ensure that production procedures do not contribute contamination from any source.

Specifically, no microbiological analysis is conducted or there is no assurance that incoming animal fat will not introduce pathogens into their production and cause contamination of finished product. Also, the firm’s current sampling procedure for animal digest does (sic) preclude potential for adulteration after sampling and during storage in warehouse. On 4/13/12, an employee was observed touching in-line fat filter and oil with bare hands.


Failure to provide hand washing and hand sanitizing facilities at each location in the plant where needed.

Specifically, there are no facilities for hand washing or hand sanitizing in the production areas where there is direct contact with exposed finished feed/food.


Failure to maintain equipment, containers and utensils used to convey, hold, and store food in a manner that protects against contamination.

Specifically, paddles in conveyor (South or Middle conveyor leading to the screeners going to packaging) were observed to have gouges and cuts, which exhibited feed residues. The damage to the paddles may allow for harborage areas for microorganisms and are difficult to clean and sanitize.


Failure to maintain equipment so as to facilitate cleaning of the equipment.

Specifically, firm utilizes cardboard, duct tape, and other non cleanable surfaces on equipment. These materials were observed to have residues adhering. The foam gaskets around access doors to the bucket elevators were observed in deteriorating condition and exhibited an accumulation of feed residues and dust.

Diamond Pet Foods recalled nine brands of dry pet foods manufactured at its Gaston plant between Dec. 9, 2011 and April 7, 2012. Several other companies whose food was also produced in the facility have joined the recall. See eFoodAlert for the most up-to-date information on the recall and product distribution.
