My impression is it would be unusual for e-coli to be in canned food. The manufacturing process is usually to cook it in the can. Assuming it was properly heated, (it's possible it may not have been) you would normally expect any bacteria present would be killed by heating. It's something agriculture departments routinely test for, so they should be able to pick it up if there was any in the food. I'd suggest contacting they to let them know what the vet found.

Here are some photos of Okizaki.
Here name is actually a strand of DNA or something-my ex was in pharmacy school when we got her, hence her name. She is the cutest little thing-only 7 lbs now.
She always seems pretty clean back there.
The food she ate were the pouches not the cans so could that still be potential?

What a cool-looking kitty!  Snowshoe Siamese, all or part?  Thanks for posting her picture!

E. coli of all forms are bacteria that are found in feces.  In view of recent problems reported in a Petco warehouse, I can envision some possible scenarios for that getting in a pouch of food, or at least on its surface and then into the food when the pouch was opened.  Or it could have been in the raw materials for the food and the food not sufficiently cooked.  It may sound like a stretch, but, as Sandi says, nothing would surprise me any more.

How is she doing these days?

yes she is adorable-she cries so cute for food and loves to curl up on clothes-she is very dainty. They actually call all cats in the Caribbean a Caribbean mix but she definitely is siamese in there!
She is eating like a champ, active, etc-back to her old self. Definitely do not regret getting her here.

Hi Everyone-I just got the lab results from the food Oki ate and got sick from the NYS Ag & Markets office

ethoxyquin and histamine were found in them - is this normal?? could these have made her sick?

that was all that was found that they tested for

Nam, thanks for letting us know the results.  Do you have levels of those 2 things, are they shown on the report?

"Toxicity

Determination of the exact threshold where these biogenic amines become toxic is extremely difficult because it is dependent on the detoxification efficiency of the individual. Upper limits of 100 mg histamine/kg in foods; 2 mg histamine/liter in beverages; and 100-800 mg/kg tyramine and 30 mg/kg phenylethylamine in foods have been suggested. Presently, fishmeal is the only petfood ingredient that typically has a biogenic amine limit specification, and this is for histamine only.

The most well-known health impact of biogenic amines is histamine poisoning, which occurs a few minutes to several hours following the ingestion of foods containing high levels of histamine. Primary symptoms in humans are skin rash, nausea, vomiting, diarrhea, etc. The toxicity of histamine is potentiated by other biogenic amines (agmatine, putrescine, cadaverine, anserine, spermine and spermidine)."
