I made a similar repair but with a smaller break using superglue (cyanoacrylate), held perfectly. However, I reinforced the broken part with a piece of a plastic card glued to the side. Consider doing that if this doesn’t hold.
I’d be concerned that the rough surface you seem to have now will be hard to clean and may get very nasty. Other than that, if it works it works.
I’m not worried about fully cured CA glue on a non-contact surface of a shelf that holds bottles/milk packs etc., or honestly even fruit whose peel you don’t eat.
Given that CA-based glues are used for wound closure and apparently even as dental adhesives, I’ll trust www.ontariopoisoncentre.ca/…/super-glue/ over the many sites that look like ChatGPT wrote them (mostly trying to sell some food safe alternative). It’s not food safe, so I wouldn’t glue e.g. a soup bowl with it, but eating an orange that sat on a cured seam in a fridge isn’t going to poison you.
