Bummer. I love sardines in water or oil! It's so brain food but has mercury it seems, just like the adult flu shots.
My cat loves tuna fish. I would never heat up her food from the refridge though. I boil a little water in the microwave ( or use hot water) and add it to the 1/2 can she gets in the evening.
Sardines and the tuna that you get in cans comes from very young fish who have not had enough time alive for mercury to accumulate in their organs. The ancient Greeks had this idea of "elements" and while they got the details wrong, the concept was correct. Elements are neither created nor destroyed outside of nuclear reactions. Mercury does not !poof! pop into fish. It slowly, inch by inch, step by step, accumulates from the environment. Big old fish can accumulate a lot. Fingerlings aren't alive long enough to do so.

Actually, according to ncbi.nlm.nih.gov and https://www.consumerlab.com/news/bes...es/07-10-2020/
sardines are contaminated with toxic heavy metals at very high levels which are exceeding the thresholds established by the Algerian and the European health authorities.
While canned sardines were low in mercury, they are very high in arsenic, cadmium, and lead.
Since fish used for animal food isn't the highest quality, the levels might be even higher.

Mercury... I believe that was the element in question.
Cadmium is of some health concern. Lead, unless you are under the age of twelve, is less so. Arsenic is frankly a false flag. Arsenic compounds were regularly used medicinally in the past with good results and people continued to live for many years. While not on a balanced diet, ingestion of some is of little or no concern to most adults. Rice has significant arsenic in many areas if you are concerned about such things.
Algerian health authorities??? And we should take them seriously because???
Your response is going way beyond what happens to sardines in a microwave, and off-topic. I can provide chapter and verse of why ANY food you might eat can be dangerous in the minds of some people. That is the current fear-factor insanity dominant in our culture. Eggs are good for you - eggs are bad for you. Salads are good - salads are bad and can contain salmonella and listeria. Drinking more water is good - water contains PFOAs and other forever chemicals. Now we are supposed to quake in fear because some Algerian doesn't like sardines? I think not. It doesn't seem a safe place in general, and is possibly subject to terrorist attacks.
Back on topic, mercury is not the cause of sparking of sardines in a microwave. Your post may or may not confirm that. I'm not going to pay a site to see a full report to dispute a post. The amounts of any metals in the various safety levels are orders of magnitude smaller than required to create sparks in a microwave.
Perhaps they have a higher mercury content than other sardines/fish? Maybe that’s why they’re cheaper?
I’m just making a guess. Now I have to go look it up.
Update: it appears sardines have very low Murcury content so… I’m wrong again.
Side note: why microwave sardines for your cats? If canned or vacuum sealed they’re either smoked or cooked and ready to eat right from the can. You needn’t reply over such a small thing, I was just curious.

A BUNCH of things happen in a microwave. The first thing in response to your speculation though, is that it is unlikely that mercury caused the arc. Many things will arc in a microwave; kale, grape skins, bits of aluminum foil, green beans, chickpeas, straight pins, and so on. .

Wow, when we dig into what is in many foods, it gives some unpleasant surprises. Sardines aren't my thing but yikes!
I sincerely think the OP means well, and is really trying to do the best for their cats, though.

Of course! I myself love to eat canned fish, and like everything else eaten in moderation isn't a problem at all.
Still puzzled about the microwave behavior. Perhaps it was the container, thus my question about it.
My first suspicion would be that there is some metal in the fish probably from the canning process, the metal used in the can or the opener.
However, if you google it could be your can-opener is the problem or the can is of a more brittle metal and when you open it little metal flakes get into the food.
