1 The single fat composite for each item (heart, kidney, tongue, oxtail) included equal g of fat from each of the three respective individual items from each of three suppliers. 2 Oxtail fat is an equal composite of external and internal fat (each composited as stated above); both types were present only for this item. 3 Values for Vitamin D3 and 5-Hydroxy Vitamin D are reported as mcg/100 g due to the small amount present in samples. 4 Menaquinone-5, -6, -7, -8 were not detectable for any fat samples. 5 Values preceded by “<” were below the limit of quantification.
