    does sodium bisulfate have a direct relationship to menadione sodium bisulfate (synthetic Vit K)? That is, of course, in all kinds of foods…

    1. Susan Thixton Author

      No – my understanding is that it does not. Menadione is the synthetic vitamin K – sodium bisulfite is the preservative. Though it would be great if a vet or manufacturer could weigh in on this and provide a full understanding for all of us.

      Ok I buy fussie cat and the label says it has SULPHATES not Sulphites…am I ok?

    Both Alpo and Beneful contain menadione sodium bisulfite. I’m sure other low quality foods probably do also. I just came across those two for examples.

    1. Susan Thixton Author

      Menadione sodium bisulfite is a synthetic vitamin K, but this does bring up a good point (as did Wolf). I will send FDA the question if this ingredient is related to sodium bisulfite the preservative. Will post when they respond.

      Well, you also want to stay away from ethoxyquin. I am pretty sure that Susan has information on this website about it.

      1. Jessica

        Yes, I know that. Thank you

    I do not find any of this in Earthborn Holistic Dog Food, Coastal Catch.
    Do they have to list it?

    It’s my understanding that the AU pet foods affected were “meat minces” – ground raw meats intended for pets sold in the freezer section.

    But from a labeling standpoint, if a manufacturer purchased meat that had already had sulphites added, would they have to list that on the label? I don’t think that they do because they (the manufacturer) didn’t add it in.

    1. Dori

      You bring up a very interesting point. Also a frightening one because I think you’re absolutely correct in your thinking.

    Interesting. I don’t know much about Vitamins, so looked up Vit. B1. It is mostly found in whole grains and some leafy green vegetables. Since most commercial dog food (not MY choice!) contains only “fragments” of grains, perhaps the sulfite preservatives (yech) really don’t have much impact on the thiamine levels. All the more reason to feed homemade….

    SUSAN, I did a quick search. The following pet products contain “sodium metabisulfite”: Pro-Pet Premium Dog Biscuits (http://www.hubbardlife.com/dog/dog-biscuit.aspx), Milk-Bone Original Biscuits (http://milkbone.com/products/original-biscuits/small/), Champion Breed Cat Food Shredded Turkey & Cheese Dinner in Gravy (http://www.kmart.com/champion-breed-cat-food-shredded-turkey-cheese-dinner/p-029W021250260001P?prdNo=10&blockNo=10&blockType=G10), Beefeaters Sweet Potato Snacks for Dogs (http://www.petmountain.com/product/natural-dog-treats/11442-579229/sweet-potato-snacks-for-dogs.html), Pedogree Breathbuster Dog Treat (http://www.petsmart.com/dog/breath-fresheners/pedogree-breathbuster-dog-treat-zid36-5205263/cat-36-catid-100039). I did not find much on any of the other listed sulphite preservatives.

    It is very sad but most consumers have no idea of the possibility of a harmful substance possibly lurking in their pet food.

    Thiamine in some canned cat foods may be too low.
    This is worrying because my family agrees with information on Catinfo.org and only feel low carb foods. We don’t want any more urinary issues and must prevent our rescued diabetic cat from coming out of remission.

    “Researchers at the Cummings School of Veterinary Medicine at Tufts University noted that five U.S. Food and Drug Administration voluntary recalls of commercial cat foods due to low levels of thiamine have been made in the past five years. This prompted them to measure thiamine concentration in commercial canned cat foods and determine effects of flavor (fish vs. moonfish), texture (‘pate’ vs. ‘non-pate’), country of manufacture, and company size on thiamine concentration. An additional low thiamine level recall was made during the publication process, bringing the total number of recalls to six in the past five years. The researchers analyzed 90 non-therapeutic canned cat foods (one fish and one non-fish flavor) from 45 brands.

    Thiamine levels were below minimum requirement set by the Association of American Feed Control Officials in 12 of 90 (13.3%) foods and below minimum recommended allowance of the National Research Council in 14 of 90 (15.6%) foods. ‘Pate’ foods had significantly lower thiamine level than ‘non-pate’ foods, and smaller companies (less than $1,000,000 in retail sales) had significantly lower thiamine levels than larger companies (more than $2,000,000 retail in sales). Neither fish or non-fish flavor nor country of manufacture had a significant effect on thiamine level. Thiamine concentrations were found over a wide range in the foods evaluated. The researchers concluded that pet food companies should strive to measure and limit thiamine loss during processing and implement strict quality control practices. In addition, veterinarians should consider thiamine deficiency in cats presenting with acute neurologic dysfunction, especially with accompanying gastrointestinal signs. [GO]”

    Dear Susan and fellow passionate dog lovers
    I live in Melbourne, Australia. I have already had some correspondence with Susan.
    Given this blog is related to “Australia”, I would like to know if anyone who subscribes to Susan’s information is from Australia, and if so, apart from what Susan advocates in her books, what Australian products do you feed your dogs?
    Susan – Not sure if appropriate to ask here, but I’m not sure if you’re familiar with VETS ALL NATURAL, an Australian line of products. Here is the website! http://www.vetsallnatural.com.au/ Any advice would be wonderful!!
    Many thanks

    I have a female tortie cat who is 15. She has always been the size of a 4 month old kitten….(7 lbs or so)
    Before I discovered Susan Thixton, she ate all the so called good foods, which as I know now are junk. The ones you buy at the supermarket.

    She has had kidney disease for several years, and the only way she has survived and even thrived is by administering subcu fluids every day (God bless my husband) She will eat a few portions of cat food every day, but prefers plain cooked minced chicken. She has been on a diet of Fussie Cat, but not exclusively. I see the culprit might be: Menadione Sodium Bisulfite Complex. What do you think about that? Fussie Cat also contains Carrageenan.
    Maggie has a wobbly gait, is blind and deaf, and has her own space, away from the big kitties. She manages to use her litter box, drinks water, eats high end canned food, and must have a big heart. She is a survivor. But where did all her health problems come from?……….all those years when I was not informed nor did I do research, and did not know about Susan Thixton. Thank God, we haven’t lost her!
