my 4 year raspberries are fruiting fantasticly but each year I have an increasing number of yellow fruit, not just from one plant but randonly spread out, they still taste fantastic but can you tell me why is this happening ?

There are yellow-fruited varieties but if the rest of the fruit is red, this is not the case.
This is possibly virus-related. However, virus generally reduces vigour and cropping.
Another possibility is contamination with weedkillers in tiny amounts, because these generally reduce vigour.
