Plum disease? #875388

Greetings!
We have a backyard plum tree that has consistently produced an incredible amount of delicious plums every single year. All of a sudden - it looks like it has some kind of disease. Can you please let me know:
1) What is it?
2) Can we treat it?
3) Can we eat these plums when/if any of them actually ripen?
Thank you so much for your time!
Best,

Expert Response
Thank you for your questions, Amy. I am unable to tell whether this is a bacterial or fungal infection from the photos. I suggest that you take samples into either the Clackamas County (https://extension.oregonstate.edu/clackamas) or Washington County (https://extension.oregonstate.edu/washington) Extension office during hours when a Master Gardener can examine them. They also have access to food safety experts to answer that question. Good luck!
