so there was a link under the pfg pattern in march of 2014. it's important to understand that a couple things. >> folks back now don't know what is a pfg. >> this is pulse gel, and that helps link the clinical to the facility. it's something we've been relying on for a while. it's not perfect because it's limited in the comparison of those organisms. and shows there is a strong link between what those organisms actually are. something like -- >> that's what you linked up in march. >> that's what we linked up in march. i'll tell you our expert analysis was not enough to show causation at that point. >> okay. >> it was done differently. usually there is a food history, what did you eat, then link that back up, then look at the pfg, that didn't happen in this case. people did something new in this case, they went through some of the data bank and linked that up. they linked it up with ffge and whole genome sequencing and excited about that. and it has been something that we've used that is linking up to the database and something very promising.

. >> all right folks back home don't know what is a pfg. >> this was pulse field. it helps link the clinical, that's the person, to what's happening at the facility. it's something that we've used, been relying on for a while. it's not perfect because it's more limited in the amount of information that in terms of comparison of those organisms. and it shows that there's a strong link between what those organisms actually are because something like -- >> and that's what you linked up in march. >> that that's what we linked up in march. i will tell you that our expert analysis that was not enough to show causation at that point. >> okay. >> there was no link, and it was done differently than we usually do if the usually there's a food history that links where they ask people what did you eat. in this case, they went through some of the databank and they linked that up. they link today up with pfge and they linked it up with whole gee nome see kwengsing and they were excited about that when it happened because it has been something that we've used that's linking up to
