Information on Natural Balance
The U.S. Food & Drug Administration (FDA) was informed today, April 16,
2007, that Natural Balance Pet Foods has received consumer complaints
regarding the Venison & Brown Rice Dry Dog Food, and Venison & Green Pea Dry
Cat Foods. The company does not know the cause of the problems, but has
received reports of animals vomiting and experiencing kidney problems.
Although the company is stating that the problems seem to be focused on one
particular lot, as a precautionary measure, the company is pulling all dates
of Venison & Brown Rice Dry Dog Food and Venison & Green Pea Dry Cat Food
from the shelves.

The company is advising consumers to discontinue feeding all Venison and
Brown Rice Dry Dog Food, and Venison and Green Pea Dry Cat Food.

The FDA is working closely with Natural Balance and is actively
investigating this problem. There is no indication at this time whether this
is related to the ongoing pet food recalls. For more information, please

Melamine again, but not associated with Menu foods, and it wasn't in Wheat
gluten.  Holy crap!  How long has this melamine been killing our pets?

FOR IMMEDIATE RELEASE -- Pacoima, CA -- April 17, 2007-- Natural Balance,
Pacoima, CA, is issuing a voluntary nationwide recall for all of its Venison dog
products and the dry Venison cat food only, regardless of date codes. The
recalled products include Venison and Brown Rice canned and bagged dog foods,
Venison and Brown Rice dog treats, and Venison and Green Pea dry cat food.
Recent laboratory results show that the products contain melamine. We believe
the source of the melamine is a rice protein concentrate.   Natural Balance has
confirmed this morning that some production batches of these products may
contain melamine.

The recall was prompted by consumer complaints received by Natural Balance
involving a small number of cats and dogs that developed kidney failure after
eating the affected product.

Dogs or cats who have consumed the suspect food and show signs of kidney failure
(such as loss of appetite, lethargy and vomiting) should be seen by a
veterinarian. We recommend our customers immediately stop feeding our recalled
venison products regardless of date code and return unused product to their
retailer for a full refund.

The products are packaged in bags, cans and zip lock treat bags and sold in pet
specialty stores and PetCo nationally.
No other Natural Balance products are involved in this voluntary recall as none
of our other formulas include the rice protein concentrate.

Although the problems seem to be focused on a particular production period of
the venison products, over the last four days we have notified our distributors
and retailers by phone and e-mail to immediately stop selling and return all
recalled Venison dog foods and treats and the Venison dry cat food. Venison
canned cat food is not involved.

The source of the melamine appears to be a rice protein concentrate, which was
recently added to the dry venison formulas. Natural Balance does not use wheat
gluten, which was associated with the previous melamine contamination.

None of Natural Balance’s other dry formulas, none of our other canned or roll
products and none of our other treats are involved with this voluntary recall.

We continue to work closely with the FDA in their ongoing investigation.
