Of these, five have had chickens with <em>Salmonella<\/em>, with a total of six chickens of 430 having <em>Salmonella.<\/em><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"491\" height=\"282\" src=\"https:\/\/blog.uvm.edu\/aetter\/files\/2021\/10\/image-1.png\" alt=\"\" class=\"wp-image-102\" srcset=\"https:\/\/blog.uvm.edu\/aetter\/files\/2021\/10\/image-1.png 491w, https:\/\/blog.uvm.edu\/aetter\/files\/2021\/10\/image-1-300x172.png 300w\" sizes=\"auto, (max-width: 491px) 100vw, 491px\" \/><\/figure><\/div>\n\n\n\n<p>What does this mean?<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>The odds of an individual chicken having <em>Salmonella<\/em> are pretty low&#8211;about 1\/100.<\/li><li>The odds of a flock having a<em> <\/em>chicken with <em>Salmonella<\/em> are  fairly high&#8211;about 12% of flocks have at least one chicken with <em>Salmonella.<\/em><\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Chicks<\/h2>\n\n\n\n<p>We have gotten though 211 chick bedding samples since March 2020. We have done 135 this year, and we still have about 65 in the freezer. So far, we have found 35 total chick bedding samples positive for <em>Salmonella <\/em>(34 this year). Of these, 75% come from hatcheries participating in the National Poultry Improvement Plan for reducing <em>Salmonella. <\/em>You can also see that we&#8217;re finding a lot more <em>Salmonella <\/em>this year, overall.<\/p>\n\n\n\n<p>We do collect data by hatchery, and we also found a lot of variation by hatchery. Our non-NPIP hatchery had the lowest positivity rate (16% of chick bedding pads contained <em>Salmonella<\/em>). In one of our NPIP hatcheries, 79% of the chick shipping pads tested positive for <em>Salmonella<\/em> (in the other, only 21% of pads had <em>Salmonella<\/em>).<\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"643\" height=\"392\" src=\"https:\/\/blog.uvm.edu\/aetter\/files\/2021\/10\/image-4.png\" alt=\"\" class=\"wp-image-105\" srcset=\"https:\/\/blog.uvm.edu\/aetter\/files\/2021\/10\/image-4.png 643w, https:\/\/blog.uvm.edu\/aetter\/files\/2021\/10\/image-4-300x183.png 300w\" sizes=\"auto, (max-width: 643px) 100vw, 643px\" \/><\/figure><\/div>\n\n\n\n<p>What does this mean?<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>This may be a high <em>Salmonella<\/em> year. Or last year might have been low. Or it might be a difference in where we&#8217;re sampling. There are, unfortunately, a lot of possibilities. We&#8217;ll know more next year.<\/li><li>NPIP isn&#8217;t working well this year. This may be due to COVID difficulties (inability to get USDA staff people out to monitor hatcheries, etc). It could also be that hatcheries cut corners this year to meet demand (especially after last year) and the USDA hasn&#8217;t clamped down on this yet. It&#8217;ll be interesting to see what we find next year.<\/li><li>Looking at trends over time is really important for drawing robust conclusions&#8211;last year, it looked like NPIP was really working well. This year, I wouldn&#8217;t spend the extra $1.50\/bird on an NPIP-certified hatchery chick.<\/li><li>There is a lot of variation in <em>Salmonella<\/em> rates among
