330 CMR 13.04
Brand and Product Names
(1) No flavor designation shall be used on a pet food label unless the designated flavor is
detectable by a recognized test method, or is one the presence of which provides a characteristic
distinguishable by the pet. Any flavor designation on a pet food label must either conform to the
name of its source as shown in the ingredient statement or the ingredient statement shall show
the source of the flavor. The word flavor shall be printed in the same size type and with an equal
degree of conspicuousness as the ingredient term(s) from which the flavor designation is derived.
Distributors of pet food employing such flavor designation or claims on the labels of the product
distributed by them shall, upon request, supply verification of the designated or claimed flavor
to the Department.
(2) The designation "100%" or "all" or words of similar connotation shall not be used in the
brand or product name of a pet food if it contains more than one ingredient. However, for the
purpose of 330 CMR 13.04(2), water sufficient for processing, required decharacterizing agents
and trace amounts of preservatives and condiments shall not be considered ingredients.
(3) The term "meat and "meat by-products" shall be qualified to designate the animal from
which the meat and meat by-products are derived unless the meat and meat by-products are from
cattle, swine, sheep and goats. For example, "horsemeat" and "horsemeat by-products."
(4) The name of the pet food shall not be derived from one or more ingredients of a mixture of
a pet food product unless all components or ingredients are included in the name except as
specified by 330 CMR 13.03(1), (5), or (6); Provided, that the name of an ingredient or
combination of ingredients may be used as a part of the product name if:
(a) the ingredient or combination of ingredients is present in sufficient quantity to impart
a distinctive characteristic to the product or is present in amounts which have a material
bearing upon the price of the product or upon acceptance of the product by the purchaser
thereof: or
(b) it does not constitute a representation that the ingredient or combination of ingredients
is present to the exclusion of other ingredients; or
(c) it is not otherwise false or misleading.
(5) When an ingredient or a combination of ingredients derived from animals, poultry, or fish
constitutes 95% or more of the total weight of all ingredients of a pet food mixture, the name or
names of such ingredient(s) may form a part of the product name of the pet food; provided that
where more than one ingredient is part of such product name, then all such ingredient names
shall be in the same size, style and color print. For the purpose of this provisions, water sufficient
for processing shall be excluded when calculating the percentage of the named ingredient(s).
However, such named ingredient(s) shall constitute at least 70% of the total product.
(6) When an ingredient or a combination of ingredients constitute at least 25% but less than
95% of the total weight of all ingredients of a dog or cat food mixture, the name or names of
such ingredient or ingredients may form a part of the name of the pet food if each of the
ingredients constitute at least 3% of the product weight excluding water used for processing and
only if the product name also includes a primary descriptive term such as "Dinner", "Platter", or
similar designation so that the product name describes the contents of the product in accordance
with an established law, custom or usage or so that the product name is not misleading. If the
names of more than one such ingredient are shown, they shall appear in the order of their
respective predominance by weight in the product. All such ingredient names and the primary
descriptive term shall be in the same size, style and color print. For the purpose of this provision,
water sufficient for processing shall be excluded when calculating the percentage of the named
ingredient(s). However, such named ingredient(s) shall constitute at least 10% of the total
product.
