Industry sign banking minnesota notice to quit secure
good afternoon everyone I'd also like to welcome everyone to the secure poultry supply plan webinar our speaker today is dr. Carol Cardona dr. Cardona is a professor and 18 health at the College of Veterinary Medicine at the University of Minnesota as Pomeroy endowed chair in avian health since 2010 and an expert in avian flu dr. Carter John abundant outreach on behalf of the poultry industry as well as served as a liaison for researchers at the University of Minnesota and Industry alike she and her colleagues at the university continue to develop disease control and continuity of business strategies including the development of the secure poultry supply plan I'll turn it over to you dr. Cardona thank you very much so welcome everyone to what I hope will be an enlightening experience for all of us and I welcome all of your questions this is a obviously a work in progress for all of us as all of our work is so if you are sharing the screen with me I look forward to continuing to do that so the secure poultry supply plan I'm going to talk about the evolution of the continuity of business plans what we've learned what we learned from getting to use the plans for the first time in 2015 the progress that we're making with the secure egg secure turkey and secure broiler supply plans and a secure poultry supply plan that puts the pieces together to make sense of all of it so do you calm this is just the beginning and it started a long time ago so bear with me as I walk you through it the first beginning the beginning of all of this was an idea and the idea was that the products from uninfected flocks in a control area could be moved to market without expanding an outbreak the science of risk assessment could be the basis for determining if and how products could move and to get the information that was needed for those risk assessments a partnership between regulators and three would be essential neither party knew enough to be able to accomplish these risk mitigations and risk assessments alone so with that in mind the secure egg supply plan was the first plan that was started that started 11 years ago it also a working group was formed that consists of egg sector professionals state and federal regulators and academics they define the importance of the monitored premises in their work and they also pioneered strategies to mitigate risk so I'm going to tell you a little bit about this strategy of the monitored premises and this idea of mitigating risk so that you can understand the basis of these plans so the new concept that came about was you know the old concept was if you get a positive test and something we all understand then you know that you have a positive premises so for example if you have seven million birds on a premises and one bird test positive that whole premise is positive that we all understand that but to build an idea of what you would have to do to figure out if that premises was mostly not positive this idea of a monitored premises came along so in that we also have the idea of a test so a test that comes out negative we then have to build on top of that a flock you know an understanding that this this premises can't have any epi links to an infected premises in other words it can't be a dangerous contact we have to also say that this premises doesn't have birds that show morbidity or mortality that could be linked to high pass AI and then you also have to have in place bio security that is of an acceptable level to state and federal regulators that monitored premises status that a farm or premises could achieve by jumping through these hoops and cheating these criteria is good for 24 hours because in the next 24 hours you could have a very different outbreak map so you could wind up getting a positive test you could suddenly have epi links to a new infected premises you could have the appearance of clinical signs or your biosecurity may no longer be acceptable so you've got to have this renewal of the monitored premises status every 24 hours so it's this is the case on the basis for our continuity of business work so to understand what that means and what we're trying to do here when you have a monitored premises and a flock or a premises that has flocks that test negative is not a suspect not a not a dangerous contact and has biosecurity that that premises is going to have a very low load of virus if any at all most likely that premises is negative uninfected but there might be some that we would call not known to be infected and by achieving that monitored premises status we know that that load of infection the prevalence of infection on that farm is very low that's in contrast to when we can detect an infection on a farm or in a flock once that farm becomes infected or is known to be infected there's a considerable amount more virus in the environment in the birds on that premises the continuity of business principles have been designed to work on that monitored premise status so that very low load of virus if any at all more than likely uninfected so that stat that continuity of this principle was first brought out by the secure egg supply the other thing that this group did early on was to develop an idea of how to mitigate risk pathways so the basis of a risk analysis is to identify the risk pathways the ways that infection could be spread by this movement so the group came up with this idea that you know for a Washington sanitized egg or any egg product there could be high path a I on the inside of an egg laid by a flock if they're infected so again from a monitored premise premises if that high path AI was on the inside of an egg it could be the way that infection could spread from that farm from that flock on that farm to a naive population so we knew that if you test that flock that laid that egg and then that same day you ship those eggs out you would have a low risk of moving virus moving high path AI from that flock to another flock but if you test the flock for an additional two days while holding the eggs laid on day zero those and the tests are negative then you move the eggs from day zero on the second day the risk goes to negligible and the reason is that on day one you have a greater chance of detecting infection from day zero on day two you have an even greater chance in other words the infection asst would be spreading in that flock so you would have a better chance of knowing it was infected so that that is how that risk mitigation works so in creating the SES the work group work together to identify risk pathways they identified them using discussions with experts they talked about it among themselves and they did extensive literature review the idea is to answer the question how could the outbreak be spread by this movement the work group then identified ways to mitigate risk and this is primarily coming from our industry partners what are your practices and what how could you change those reasonably in an outbreak to reduce the risk of spread much like that example of holding eggs for two days those risks then with mitigations are modeled and the risk assessment is written so any example of washed and sanitized eggs those risk pathways are basically for high path a I could be on the inside of the egg and so the mitigation is as i described hold the eggs for two days while continuing to test the flocks the flock remains negative there's negligible risk that that those eggs that were laid contain high pate I hipath AI could also be on the packing materials as it shipped out well you're only allowed to use new packs so it can't be there hipath AI could be on the outside of the of an egg you know if it's got fecal contamination or small bits of Heather no these are washed and sanitized and this points out the need to make sure that each of our risk assessments are applied correctly to the right commodity because that certainly is a valid pathway for the move of nest run eggs finally hipath AI could be on the truck or driver so that's true and that's a valid pathway that's not mitigated in our in our risk assessment so that is the permanent criteria for the movement of washed and sanitized eggs to from a premises that has poultry to a market or a premises that doesn't have poultry so the permit criteria is for truck and Driver bio security so we look again at this diagram you can see again for a positive premises a single test is what you need to make sure that it to say that it's positive to move washed and sanitized eggs to market you would have to have 2x on two 24-hour periods where you're doing the you are monitored premises that will achieve your whole time and then you have to have truck and Driver biosecurity so in order to move washed and sanitized eggs you have quite a bit of work to do and quite a bit of monitoring the six-year egg supply plan consists of risk assessments that address commodity movements with those mitigations they've been modeled and the risk assessments written the risk that are are assigned from negligible up too high and the products in this the secure egg supply are all eggs based products and you can see them arrayed against the the risk categories if you're interested in reading those risk assessments or seeing the work it's available online at the at the URL listen listed you know in case anybody has it and wants to get over it the same process was used to develop the secure turkey and secure broiler supply plans as I described for the secure egg supply plan a work group was formed with industry regulators and we academics or service moderators and risk Assessors we asked the question how could the outbreak be spread by this movement and which movement we determine that based on the needs of that those industries we then asked the industry people particularly what could be done to reduce risk and based on those risk pathways and risk mitigations we write and model the risk assessment so the secure turkey and secure broiler supply plans we first did hatching egg movements and Dale bird movements from hatcheries and we did that also for the secure egg supply planned and that is what is online at the secure of royal air supply and secure turkey supply URLs but where the secure egg supply plan focused on eggs and egg products those aren't really relevant for the broiler and turkey commodity so we had to branch into live bird movements which is extremely difficult and you know requires kind of a different level of thinking so these are going to be higher risk movement and are going to require new approaches so just like the secure egg supply folks came up with innovations around how to mitigate pathways and this idea of monitored premises we're now looking at live bird movements and how we're going to accomplish the security of those movements so a new concept this came out of our our turkey working group is this idea of a pre movement isolation period and we're which is a period of extreme bio security prior to the movement of birds this idea is to minimize the chances of a flock being exposed to high cafe I close to the scheduled movement date this reduces the overall likelihood of moving and infected and undetected flop so how does it work well you know most of our ideas are are around you know how can we best detect or easiest most rapidly detect an infection and so it a lot of the work that we do is based on excellent modeling done by our partners at sia and also by our own excellent University of Minnesota modeling team and like to give a shout out to shashi Malati who you know for many years has been you know doing all the hard work beside behind this and and the rest of us just get to take credit for it so thanks to shashi this is in his team this is one of the things we see so if a flock is infected several days before movement it would likely be detected by the tests that are required to get a permit so in other words you would be able to detect as the number of infectious Birds increase you would be able to detect those birds given the pool sizes and the number of tests that are required prior to movement but if the exposure happens closer to the time of movement it becomes very difficult the number of infectious birds doesn't go up very much and the number of dead doesn't go up hardly at all so there's not very much infection there but there it's also very difficult to detect because if there's a long prodromal period in other words the birds aren't showing many clinical signs you can't figure out which birds have the infection and so if we take the example of 20,000 turkeys which of those 20,000 need to be tested to detect the hundred that have the infection so it becomes increasingly difficult to find so this idea of the pre movement isolation period was brought up in order to address that or to mitigate that risk and what what it does is this the PMI p starts so in order to prevent exposure that would occur close to movement so we block out the opportunity for exposure during that period of time and why is the PMI p how is the length of that P MIT determined well it's determined much of it in partnership with our friends at southeast poultry research lab who for example give us numbers around mean duck times how quickly could a poultry farmer detect find dead birds that rise above the level of expected tality so how long after in exposure can you detect in section and that's that's going to be the factor that determines or TM IP so if we go back to our original you know pile of things to do you can see that it continues to get bigger and bigger and you know again for a positive we have a single test for moving live birds which is a much more dangerous movement than moving washed and sanitized eggs from a control area you have to have eight days of monitored premises for 24 hours each you're going to have this pre movement isolation period which means no non-essential visitors no garbage pickup no off-site manure litter or mortality movement no bird movement and enhance personnel bio security you're also going to have right before the movement you're going to have truck and Driver biosecurity to do during the movement you're going to have loadout biosecurity live hall bio security and you're going to have to determine the route that does not go near any other poultry premises so establishing the negative case and establishing that you're not going to spread disease along with the movement of product is a very very labor-intensive situation so then we got to use these plans and I think most of you are aware that you know we had a very large incident in the Midwest and in the West the largest foreign animal disease a break in US history ended towards the end of june and 2015 during that outbreak as it relates to this continuity of business plans we learn several things we learn that for each and every positive case there are going to be many many non case premises that will want or need to move product that effort is going to require workforce and infrastructure and i think you can see from those piles that we've created just how incredible that workload can be we found out that you know the guidance and permits that we had written from our ivory tower perspective were to detail for regulators to use as is and we had created different types of permit guidance for similar and different products which resulted in confusion between different commodities so the idea to fix this was to create a secure poultry supply plan this plan is supposed to facilitate poultry and poultry industry and state regulatory agency preparedness for product movement in a high-pass AI outbreak so the idea was to create a harmonized approach to permitted movement where we linked the science of the secure egg boiler and turkey supply plans to permitted movements in an outbreak so as you know science is the language that we've used in these risk assessments and the reason is that the movement of products from a control area into a region with a dense poultry population is scary it's scary for you know the guy who's invested his life savings in that broiler flocks and it's scary for the company whose systems you know spread through out of state or throughout a region and it's scary for regulators who don't want to see this spread it's scary for everybody the risk assessments of the continuity of busin
ss plans provide a way to understand that risk even if you're not familiar with the specific activity so the risk assessments give a rating from negligible to high and that rating should help to allow different industries and regulators to understand what those risks might be so for example how would a broiler company understand the risk to them of an egg production farm moving washed and sanitized eggs well that's going to be as I described the negligible risk movement so if you said we're going to move something from an egg production farm into a broiler dense area you know you might freak out a little bit but we said we're going to move a negligible risk product this is specifically how it's going to done the transparency and the risk rating help to help people to understand what's actually going on so the science is still there and that comes from our sts LCS and SBS plans the SPS the secure poultry supply plan is built on that science the science of the risk assessment are the basis for the permit guidance in the SPS so that permanent guidance is boiled down from those hundreds of pages at our risk assessments the permit guidance is then the operational part of a risk assessment so question what do I need to do to mitigate risk when moving washed and sanitized eggs from a monitored premises answer look in the secure poultry supply permit guidance for that product and again as those permit guidances are not all a cart you have to apply the whole thing in order to get to that status that we've we've we've modeled next step of the six year poultry supply was to create a permitting process that balances the work required for permitting between the industry and the state and a standardized process in immerse for getting a permit and communicating with other states that may be involved so this document shows the the e MERS process you know the steps of getting a permit request and what we're talking about today is really the things that are happening upstream of that permanent request and what would be referred to if you wanted to question or ask how were these criteria met so this idea of a monitored premises so biosecurity not a suspect premises not a dangerous contact- pcr test has to be met then the permit criteria has to be met so you know that those that permit criteria for Washington sanitized eggs would be two days of whole time seeing every day and truck and Driver value 60 those things this monitored premise of status and Miss meet the permit criteria is we're here in Minnesota we have worked on establishing that with our state so the poultry industry and the state have worked together to create a more streamlined approach that is now part and we've tried to learn the lessons from from here so one of the things was to take those two things and create permits that rebalance effort between industry and state one of the things that happened during our outbreak are overwhelming outbreak here in Minnesota was that the state had to take on too many details of movements that that were hard to understand so the solution has been to ask industry to certify compliance with specific permit guiding specific for that commodity and product for example the reason is there's not enough people with the type of knowledge specifically needed to understand the details of a permit what is a hatching egg vs what is a washed and sanitized day there's differences between those two products that affect their risk of movement there are plenty of people in industry with this type of expertise so what we've come up with is something slightly different the idea is that the state will receive a request that says the requester has certified completion of the steps the state will add and verify test results and issue permit or not issue the permit based on those test results the certification the monitor premises status and was following a situational assessment the details then of the process falta industry the state received certification and can audit at any time so the solution industry has to assure that all criteria are met they have to be able to know the details of the engine that operates a farm the state has to see or the regulators have to see that appropriate assurances have been met in other words they have to be able to drive the car so in my world you know I definitely can drive my car I definitely cannot rebuild the engine and I don't have that kind of specific knowledge and so we think that this is a reasonable approach to help rebalance that effort finally we've worked hard with a number of partners to harmonize movement criteria where possible so harmonization became a problem just through the process of how these risk assessments were written they're written by several work groups that operated independent of each other and those different work groups had different approaches to developing the criteria needed for movement how the in the anvil though so what we've done is we've changed the risk assessments and we found the places that are the same and try to harmonize those things so that each of the risk assessments and the permit guidances look more similar but in the end only some things can be harmonized and some things are actually biologically different so the harmonization is not going to be the plans are not identical and they never will be but they are much more harmonized so we harmonize the traceability definitions and each of the plans the monitored premises definition is now the same the permit movement guidelines are continuing to be harmonized for hatching eggs Dale poults and chicks and birds to market sampling protocols are being harmonized and PMI t discussions are ongoing so to conclude this the big idea was that we could predetermine ways that product could be moved during in our outbreak and it did work the SES SBS and STS plans are addressing additional movements through the work group and risk assessment process both as independent work groups and now we're going to introduce a cross commodity work group between members of those three industries to help them discuss high and moderate risk movement the plan the plans weren't operation ready so after the hiccups of 2015 we've developed a more harmonized more straightforward approach that will be more manageable for state and federal regulators in an outbreak industry and regulatory agencies needed to rebalance their efforts and permitted movements and so we think that that has happened and the how to move product plan is now called the secure poultry supply plan and is a welcome addition to the secure egg broiler and turkey supply plan so I like to end this with a pitch before I answer questions but we're always looking for new work group participants so if you're interested please let us know and now we do a little orientation for people so that that you can understand the continuity of business principles but if you've been on this webinar I suppose you have that already so thank you and with that I'm happy to answer any questions you might have ladies and gentlemen as we move to Q&A please feel free to place yourself into the question to you by pressing pound too that's bound to on your telephone keypad voice over computer users you can select whether they use an emoticon for the top toolbar you will hear a notification when your line has been unmuted you can also send in a written questions by slicing the participants menu at the top of your screen and opting to send note to all presenters if you're logged in using the web based application please use the notes tab on the bottom right-hand side of your screen and if you're to note to all moderators we did have a written question that was submitted a little bit earlier asking how is in quotations near a poultry premises defined in the context of determining movement routes for live birds what data is this based on just a really good question we do have a little bit of data that that will be based on but that's not going to tell you I don't think that's a completed risk-based guidance at this point okay we do have another question p.m. I period what about contact with wild birds ventilation allows access how is this addressed in the RA so the risk assessment the wild bird root of introduction is sort of a constant the risk the PMI period p.m. IP period addresses personnel bio security so that's one way one way that wild bird access is prevented the bio security in the monitored premises status should include wild bird proofing and and limitation of access to wild birds so this is the line of separation idea that's out there so we it's included in the monitored premises piece and also the increased personnel biosecurity in the TM IT addresses that question ventilation allows access so the ventilation the as you know the you know the ideas of airborne transmission were not were not borne out in in this particular outbreak that we had and so ventilation access are the birds are ventilated during a PMI p period so say the the more important parts of of line of separation our personnel equipment and those are all addressed in the PM IP period they have another question outlets submitted acting have these risk mitigating parameters been analyzed for low pass a I have these risk mitigating parameters then analyzed for love how they are so so the low cafe I question is it many of the risk assessment work is based on low pass AI or some of it is based on low pass a I ideas but mostly you know it is quite different high pass a I and low pass a I transmission detection you know the infected but undetected state those are very very different so the low pass a i infected that undetected state is common where the high pass AI is it's more easy to detect if you take these mitigation strategies so i'm going to say apples and oranges on that one I okay we have another question asking did the risk assessment fail during the Minnesota outbreak and resulted in additional positive premises due to the movement of bird so first of all at the time of the Minnesota outbreak we didn't have risk assessments in place for the movement of birds second of all to our understanding there's no evidence that anything that the outbreak was moved during by the issuance of permits during the outbreak so I guess my answer is no they did not fail can we have another question asking can you elaborate on the data that will be used in the risk assessment of moving product near or other near howard apartment near in quotation marks other poultry premises I think I answered that one right so the souvenir we have some data on on near poultry premises but you know I can elaborate that that the transmission events that we know about our low path AI so there's an example of how it would be based on a low pass a I transmission event I can answer that more maybe later privately I can show you some of the data okay they have another question asking for permit approval why are the pass-through states not included in front of the presence of steps five and six so the pass-through state of so the this is talking about the the ears process I believe and the reason is that the the product would be in a enclosed transport vehicle and so the truck and Driver bio security should mitigate the risk between those those states or the past through states have limited or no risk from that plum net movement the past the if we go back to where our risk assessments and product movement have been done they're based on negligible to low-risk products the question you know I think maybe referring to future movements of things that can't be an enclosed vehicles like live birds and I think that's a very different type of question so we you know it would it would definitely have to be a consideration there because lots of things do come off of trucks as you move them as you move live birds so good question probably two different categories of things so the past three states are not considered because the presumption is that the material is in a an enclosed conveyance but the past through states are important if we're talking live birds and again as a quick reminder if you'd like to ask a question over the phone lines you can simply press pound to on your telephone keypad if you're using voiceover computer you can click the Rays pan emoticon in your top toolbar and at this time we do not have any additional questions that have been submitted and there are no people waiting to ask questions over the phone line okay well thanks everybody for joining the webinar and watch your um emails were to have a another webinar in October on the secure milk supplied plugin so thank you everyone and thank you back your cardona thank you all have a great day
