There are one or two forum users that are fairly familiar with this problem and I will try to contact them over the next few days if they do not post.

I am familiar with the organism and it is not one that you want to have in your cheesemaking environment!

It is fairly insensitive to salt, tolerant of normal cheese pH values, it is also an anaerobe and pigmented.

Since the organism is commonly found on hands hygiene control will probably have to feature strongly in its eradication.

Because it is pigmented and fairly robust it is relatively easy to enumerate and 'follow' in plants.

Some strains will not grow below 12C so temperature control MAY be useful.

This organism has been used as a surface ripening 'starter' in some cheeses. Fair amount of info available, hopefully others may comment.

I have come across a strain of S Xylosus (non pathogenic) which is causing some intermittent discolouration in Emmental Cheese. Anyone ever have this experience? If so any suggestions?
