Odd plastron pattern

[Jackdean02]

Hello, I was giving my tortoise a soak today and some washed up food stuck in her claws made me worry and check her plastron thoroughly. Not sure if it is supposed to look like this but reading posts on shell rot and blood poisoning have me worried. Any help would be massively appreciated.

I don't see anything to worry about.

Looks normal to me.
