I've been looking at the issue of food fraud for quite a while now, reading up on instances of it being caught from examples of blatant adulteration, to processing in terrible environments, to labeling food with brand name labels to false organic/kosher/halal claims. As unfortunate as it is, there sure are no shortage of examples of food fraud out there. The biggest challenge I've found (other than easy, inexpensive and accurate detection of fraud or adulteration) is being able to monitor for recent and relevant events as they occur. On a variety of other threads I've seen people mention a few places to look, but I thought perhaps if there was a centralized post for databases and news sites that report food fraud, it could be quite useful for IFSQN members, as some companies will be able to buy in to a project like the USP's database (a $1200/year subscription) whereas other smaller companies like mine may need to find a different method.
In terms of databases, I know of the USP's food fraud database with a subscription fee. I've recently discovered HorizonScan by a company Fera Sciences that also requires a subscription, not sure how much, but it looks like it could be quite useful. There is the RASFF portal that has a bunch of interesting info from a bunch of Euro countries. I just came across another database that is under development in the EU called FARNHub (Food Authenticity Research Network Hub) that sounds decent and it should be online in 2018.
In terms of news sites I know that there are waaaay more of these. I had just recently discovered Trello and it seems quite neat, very concise and informative and seems to pull from a wide number of sources. There are also the OPSON reports, done by the Operation OPSON VI (in 2016-17), an originally EU and now international effort to combat food fraud (I think you have to pay to see the actual reports).
