1How to maintain internal Biosecurity when flock infected with Low pathogenic avian Influenza?How to maintain internal Biosecurity when flock infected with Low pathogenic avian Influenza?Because to the importance of A.I., infected farm should report to the authorities and follow the rules established. If regulations state that (other) houses can still keep animals, strict biosecurity rules should be applied. Different clothing and footwear for each house + house specific materials. Nothing that comes into contact with the infected flock can come into contact with other  animals. Those topics will be covered in Webinar #6&7.
2How to use Stalosan F in animal house? what is recommendation dosage per area of disinfectant? Is there any approved effective dilution from reliable laboratories against major viral diseases in pigs and poultry?  Preventive application of Stalosan F is 50gr/m² weekly. For disease control the frequency of application should be increased to 2-3 weekly(same dosage). Stalosan F is ready to use product. We have plenty of tests made worldwide. Some viral tests(PRRS,PED, TGE - pigs, A.I., IBD - poultry)  are made by the University of Minnesota.
3 What type of disinfectant should be used inside the shed in the presence of chicken & during diseases outbreak?According to the legislation liquid disinfectants are not alowed for application in presence of animals. Moreover, due to dilution,  they are not effective in presence of organic materials. Stalosan F is the only powder disinfectant registered for this purpose. In addition, try to keep infections out by applying high external biosecurity standards (washing of hands, changing of clothes, footbaths, closing off the houses, ...)
4The antimicrobial resistance is not only amongs animals, there is also one health side of it, what do you think about it for the future? (question directed to Professor Dewulf)The subject has been effectively recognized as a broader ONE HEALTH scope, optimistically the synergy of the tripartite collaboration would bring the political will necessary to deal with the responsible use of Antibiotic. We have seen substantial reduction of Antibiotics Use happening but not enough information/analysis on the overall impact at ONE HEALTH level, both Human & Animal.  For deeper knowledge on the subject, I would recommend the book I have written on the subuject in “8 myths on antimicrobial resistance disproved, practical guide for reducing antibiotic use in animal husbandry”.
5How is Stalosan F in general used in pig stabels? And how in farrowing houses? 

The Standard application of Stalosan F application is once a week, 50 gr/m². In high pathogen pressure or increased mortality/morbidity it can be used more fequently (according to the situation).  For farrowing house application we have a separate document (see attachment t3://file?uid=767)

6What should the best biosecurity plan regarding Avian influenza include?This is difficult question to answer. There is no one standard answer to fit all farms' layout. Therefore, we recommend to follow strictly the 5 biosecurity principles adapted to the epidemiological situation & pressure and proceed for biosecurity system assessment of the particular farm in order to get the best advice! to test the level of biosecurity on your farm and find potential weaknesses you may want to ues the biocheck.ugent scoring system (free for use). This will likely help you to find the optimal strategy.
7Can Stalosan reduce the incidence of foot pad dermatitis?We have several trials, showing foot pad lesions reduction of about 30 - 35%. 
8How important is it, maintaining the dirty and clean area in the farm?It's very important. This is the way to prevent introduction of diseases into the farm.
9Do you send e-certificates at the end of the webinar?Sanphar did not consider issuing e-certificates in 2021 Biosecurity Awareness Program. But we are willing to consider it for the next year's program, including a proper evaluation of the participants' knowledge.
10Are there any specific and immerging points of operational biosecurity?One of the very critical points: Application of the biosecurity principles in daily routine.
11Which type of disinfectant is more effective against viruses like Avain Influenza and IB?There are many active substances with very good antiviral efficacy like bleach, hydrogen peroxide, etc.   However, for efficacy it is most important to look at the recommendations and requirements of the product intended for use.
12What is the main ingredient of Stalosan F?Stalosan F is based on mixture of minerals. The overall effects come from the synergy between ingredients.
13 What are necassary precautions when using or storing of stalosan? (e.g. direct sunlight, humidity, water immersion etc.)According to the instructions, Stalosan F should be kept in original bag in a dry place.
Sunlight does not have any negative effect, however water/moisture can cause clumping of the product. 
14Will you consider including formaldehyde to sanitize feeds?  What are your thoughts about it?Formaldehyde is the aldehyde primarily used in commercial feed treatments and has been shown to exhibit antibacterial efficacy by irreversible cross linking of proteins. When used as a feed additive it has been shown to be one of the more effective compounds for reducing Salmonella levels in feeds (Carrique-Mas et al., 2007; Cochrane et al., 2016). However, Carrique-Mas et al., (2007) has pointed out that concerns have been raised regarding safety to humans (Arts et al., 2006). More recent risk assessments (EFSA, 2014) have concluded that formaldehyde used for animal nutrition purposes would not be expected to be a risk for the environment but anyone handling the product should avoid exposure to the respiratory tract, skin, and eyes. The other consideration with the use of formaldehyde is the potential to reduce feed protein availability for digestion. Tamminga et al. (1979) concluded from studies conducted with ruminants that formaldehyde was effective in treating feed proteins to become resistant to proteolytic rumen microorganisms and thus escape relatively unscathed to the lower part of the digestive tract where they can be used by the ruminant animal. However, Tamminga (1979) also noted that if concentrations were too high, over protection of the proteins occurred where not only were proteins protected from rumen microbial proteolysis but also now were resistant to ruminant animal proteolytic enzymes resulting in a negative ruminant animal nutritional response. Formaldehyde as a antimicrobial feed additive has not been generally observed to cause adverse responses in animals (Wales et al., 2010). However, the impact on protein availability for the concentrations of formaldehyde used as a feed antimicrobial treatment may need to also be considered.
15Can bacteria also become resistant to the used disinfectants?Theoretically this is possible however in the field we do not see this happening in animal production. Especially not if you use disinfectant products that are blends of different active ingredients. If a disinfectant is not working properly it is typically because it is not used in the correct way (e.g., wrong concentration, dilution due to application on humid surface, no proper cleaning before,...)
16Do the soaps work with all disinfectants?Yes there is no specific link between the type of soap used and the type of disinfectant used.
17Can I use household soap to clean?Yes that is possible however when you use typically developed types of soap that stick longer to the surface you will get better effects.
18Is cleaning during the summer or the  winter different (e.g., other products or procedures)?The same products and procedures apply, the only thing to consider is that when it is really cold the stables should be heated before you start the disinfection as effectivity of disinfectant products will be lower at low temperatures.
19How do you use Stalosan with hatching eggs?Stalosan application in breeders is the same as as for the other animal species - 50 gr/sq.m. over the litter once a week. The only difference is the additional nest treatment (for individual boxes) or automatic nest boxes together with egg transporting belt.
20Do you use the same disinfectant for two cleanings?You can use two times the same disinfectant product or two times different products both are possible and effective.
