Allrecipes has suffered a breach whereby customer emails and passwords appear to have been compromised. It has been emailing its customers advising them to change their passwords. 

This is good, but, as Graham Cluley points out, there doesn't appear to be any public statement on the website or tweet to acknowledge the fact. 

Unfortunately, for the users, there isn't much they can do other than:

1. Change their Allrecipe passwords

2. Ensure they don't reuse passwords, if they do, to change on all affected services

3. Sign up to a service like havibeenpwned.com to check to see if their credentials have appeared in any other breaches
