Even removing the moldy part and scraping away the bottom layer exposes you to danger. This could be because hazardous compounds have made their way into the deeper layers as well. Furthermore, the spores that cause the formation of these molds are exceedingly minute, making them impossible to detect with the human eye. There is a chance that these spores will remain in the tomato paste. As a result, it appears that even completely removing the mold from the paste is insufficient to remove the toxins or spores that it produces.

Is mold on tomato sauce dangerous

This is due to the biological components that comprise the fungus itself. Mold is a dangerous type of fungus that reproduces by creating spores and disseminating them through the air. When the paste begins to mold, the mold begins the process of creating mycotoxins, which are poisons. Even after scraping away the layer below the moldy piece and completely removing it, there is still a risk in the procedure. 
Poisons may have found their way down into the soil's lower layers as well, which would explain this behavior. Furthermore, the spores that cause the growth of these molds are so tiny that they are not visible to the naked eye when present. There is a possibility that some of these spores are still alive and well in tomato paste. Even if all of the molds are totally removed from the paste, it does not appear to be possible to remove the toxins or spores that the mold generates. Even when the mold has been entirely cleaned, this is still the situation. Naturally, no potentially deadly infections caused by moldy tomato paste have been discovered as yet. This is due to the fact that no such infections have been detected. This fungus can produce a trace level of toxicity in its environment. On the other side, there have been reports of persons who are allergic to paste mold having terrible responses.
