Food labels are regulated by what 2 organizations? Which is mandatory and which is optional?
- Food and Drug Administration (FDA) - manditory
- Association of American Feed Control Officials (AAFCO) - optional
Explain the 95% rule in pet food labeling
- Applies to products containing meat, poultry or fish.
- If they use beef, tuna etc in the name of the food, the food must have 95% of the product must be the named ingredient not counting water.
- Counting the added water, the named ingredient must still comprise 70% of the product.
- If the food has two listed ingredients, the two must comprise 95% of the total weight and the 1st ingredient must be the one with high predominance in the product.
Explain the 25% rule AKA
- Dinner, platter, entree, nuggets, receipe and formula
- Name ingredient must comprise 25% (not counting water) but less than 95%
- Counting water the named ingredients must comprise 10% of the product.
- 2 or more ingredients (Chicken n' fish dinner) must have 25% chicken and fish combined and at least 3% fish.
Explain the 3% rule or "with" rule
Allows the use of the term with as part of the product name if the product contains at least 3% of the named ingredient is contained.
Explain the "flavor" rule
Specific % is not required, but flavor must be detected. Tested utilizing animals trained to prefer specific flavors. The word flavor must be the same size type as the other words on the label.
What are "digests" with respect to flavor?
Materials treated with heat, enzymes and/or acids to form concentrated natural flavors
Net Quantity Statement refers to what?
How much product is in the container.
What must be included on the label
Manufacturer's name and phone number at the least
clean flesh of slaughtered mammals and is limited to striated muscle with or without the accompanying or overlaying fat and portions of skin, sinew, nerve and blood vessels which normally accompany the skin.
Define meat meal
Product from mammal tissue, exclusive of any blood, hair horn, hide trimmings, manure, stomach and rumen contents.
Which is better and why?
Corn listed as the 1st ingredient and meat meal list second
meat listed as the 1st ingredient
- Corn listed as the 1st ingrediant because meat is very high in moisture (appr 75% water). On the other hand, water and fat are removed from meat meal, so it is only 10% moisture (what's left is mostly protein and minerals).
- comparing both products on a dry matter basis ("remove" the water), one could see that the first product had more animal-source protein from meat meal than the first product had from meat, even though the ingredient list suggests otherwise.
Define Guaranteed Analysis
- the minimum percentages of crude protein and crude fat, and the maximum percentages of crude fiber and moisture.
- The "crude" refers to the specific method of testing the product, not to the quality of the nutrient itself.
What are the guarantees for
- Cat foods: taurine and magnesium.
- Dog foods: calcium, phosphorus, sodium, and linoleic acid.
A "complete and balanced" pet food must be substantiated for nutritional adequacy by one of two means.
- 1. for the pet food to contain ingredients formulated to provide levels of nutrients that meet an established profile. Presently, the AAFCO Dog or Cat Food Nutrient Profiles are used.
- 2. the product is tested using the appropriate AAFCO Feeding Trial Protocol(s). This means that the product, or "lead" member of a "family" of products, has been fed to dogs or cats under strict guidelines and found to provide proper nutrition. These products should bear the nutritional adequacy statement "Animal feeding tests using AAFCO procedures substantiate that (name of product) provides complete and balanced nutrition."
What requirement does a product labeled for senior diet mean?
a "senior" diet must meet the requirements for adult maintenance, but no more.
A product that does not meet the maintenance or growth methods for substantiation of nutritional adequacy must state that "this product is intended for intermittent or supplemental feeding only," What are the exceptions?
unless the product is conspicuously identified as a “snack,” “treat.” or “supplement.”
Define the term natural
lacks artificial flavors, colors, or preservatives in the product.
Are premium, ultra premium or gourmet better?
Products labeled as premium or gourmet are not required to contain any different or higher quality ingredients, nor are they held up to any higher nutritional standards than are any other complete and balanced products.
