Descripción

In January, egg prices reached an all-time high.  And are predicted to rise by over 40% in 2025.This is in part attributed to a "man-made crisis" caused by culling millions of chickens when bird flu appears in a flock. In this episode we look at why culling is practiced, how it affects the production of eggs, and the USDA's new plan to control the virus and bring down egg prices Sources referenced in this episode https://www.usatoday.com/story/money/food/2025/02/26/egg-prices-to-rise-2025-usda/80452571007/ [https://www.usatoday.com/story/money/food/2025/02/26/egg-prices-to-rise-2025-usda/80452571007/] https://www.foxnews.com/video/6368903426112 [https://www.foxnews.com/video/6368903426112] https://www.forbes.com/sites/mollybohannon/2025/03/06/elon-musk-says-biden-ordered-insane-slaughter-of-150-million-chickens-but-culls-are-usda-policy-to-stop-bird-flu-spread/ [https://www.forbes.com/sites/mollybohannon/2025/03/06/elon-musk-says-biden-ordered-insane-slaughter-of-150-million-chickens-but-culls-are-usda-policy-to-stop-bird-flu-spread/] https://www.avma.org/news/cat-deaths-linked-bird-flu-contaminated-raw-pet-food-sparking-voluntary-recall [https://www.avma.org/news/cat-deaths-linked-bird-flu-contaminated-raw-pet-food-sparking-voluntary-recall] https://www.wsj.com/opinion/agriculture-secretary-brooke-rollins-my-plan-to-lower-egg-prices-6be0f881 https://www.science.org/content/article/u-s-conditionally-approves-vaccine-protect-poultry-avian-flu https://www.nationalchickencouncil.org/bipartisan-bicameral-members-of-congress-seek-assurances-for-chicken-exports-as-part-of-bird-flu-strategy/ [https://www.nationalchickencouncil.org/bipartisan-bicameral-members-of-congress-seek-assurances-for-chicken-exports-as-part-of-bird-flu-strategy/] https://www.foodandwaterwatch.org/wp-content/uploads/2025/03/RPT2_2502_ [https://www.foodandwaterwatch.org/wp-content/uploads/2025/03/RPT2_2502_]EconomicCostEggs.pdf

E3: The ongoing threat of avian flu in dairy cows

In this episode, we're breaking down how bird flu has spilled over from wild birds into dairy cow herds, impacting the milk we drink. Join me, Caroline Zeiss, as we explore why this is happening, how we could control it, and what it tells us about the increased risk of bird flu spreading to humans. "The VirusDiaries" is written and recorded by me in Guilford, CT. I’m a Professor of Comparative Medicine at Yale University School of Medicine.

E2: How government layoffs could derail how we track the global bird flu pandemic

We are in the midst of the worst bird flu crisis on record. This pernicious virus has established footholds on every continent except Australia. In this episode we focus on wild birds and mammals to look at how the virus entered the US and how it has devastated animal populations across the planet. We’ll shed light on how US and international agencies work together to track and report the virus in birds, animals, and humans, and how recent US federal layoffs threaten to derail this complex system.  How bird flu entered the US https://www.cbc.ca/news/canada/newfoundland-labrador/avian-flu-newfoundland-labrador-1.6304817 [https://www.cbc.ca/news/canada/newfoundland-labrador/avian-flu-newfoundland-labrador-1.6304817] https://www.usgs.gov/centers/nwhc/science/avian-influenza-surveillance [https://www.usgs.gov/centers/nwhc/science/avian-influenza-surveillance] Caliendo V, Lewis NS, Pohlmann A, et al.
