Understanding waterfowl movement and bird flu

While poultry houses are at risk, those encountering geese in neighborhoods don't need to be too concerned for themselves or their dogs, according to a University of Delaware expert

Scores of waterfowl are currently on the move, and experts are worried they could further spread highly pathogenic avian influenza, commonly known as bird flu. But these flocks, which can number in the thousands and include Canada geese and snow geese, are of most concern around poultry houses, said University of Delaware’s Christopher Williams. The risk to humans and dogs getting bird flu from geese who inhabit their neighborhoods remains low, Williams said.


Williams, a professor wildlife ecology in UD’s College of Agriculture and Natural Resources, explained why this is happening:


• Smaller ducks such as blue-winged teal, larger ducks such as mallards, and larger geese like Canada geese and snow geese are heading north to their breeding grounds.


• Waterfowl are a primary reservoir for avian influenza viruses, meaning they can harbor bird flu strains viruses, spread them, and in some cases show no signs of disease. They can shed the virus through their saliva, naval secretions, and feces.


• Waterfowl serve as the primary vector of avian influenza to the U.S. poultry industry which has affected more than 8 million commercial and backyard chickens and turkeys that have been culled to keep the virus from spreading.


“While we are worried about these flocks congregating near poultry houses, the risk of humans getting bird flu from waterfowl remains low,” Williams said. “Further, walking dogs around areas with geese flocks should pose little threat to dogs’ health as avian influenza is very rare in dogs.”


Nevertheless, Williams cautions people and dogs to avoid touching sick birds or dead birds.


A large segment of the Canada geese population are not migratory, Williams said. They will stick around the Mid-Atlantic year-round and tend to congregate and breed near grocery store parking lots, golf courses and neighborhoods.


“Those birds are being drawn to needing two things. No. 1 is they need water including any natural pond or water containment area,” Williams said. “And all the geese species are herbivores, so No. 2 they eat grass. There are places that have both water and grass that will provide ideal nesting habitat for the geese and their chicks.”

Tariffs fuel global sourcing shakeup for fashion in the U.S.

Be prepared to see more Made in Vietnam or Made in Bangladesh labels on clothing in the coming years. That’s because U.S. fashion companies are rethinking their global sourcing strategies and operations in response to the Trump administration’s trade policies and tariffs, according to new research by the University of Delaware's Sheng Lu. Lu, professor and graduate director in the Department of Fashion and Apparel Studies, partners with the United States Fashion Industry Association (USFIA), on an annual survey of executives at the top 25 U.S. fashion brands, retailers, importers and wholesalers doing business globally. Members include well-known names like Levi’s, Macy’s, Ralph Lauren and Under Armour, among others. The report covers business challenges and outlook, sourcing practices and views on trade policy. “We wear more than just clothes; we wear the global economy, the supply chain and the public policies that jointly make fashion and affordable clothing available to American families,” Lu said. “We want to know where these companies source their products and what factors matter to them the most. It’s a classic question and it evolves each year.” This year’s report, released on July 31, shows tariffs and protectionist policies are the top business challenge for companies, with nearly half reporting declining sales and more than 20% saying they have had to lay off employees. This was followed closely by uncertainty around inflation and the economy, increasing sourcing and production costs, and changes in trade policies from other countries. In response, more than 80% of companies said they will diversify the countries from which they source their products, focusing on vendors in Asian countries such as Vietnam, Bangladesh, Cambodia and Indonesia. Despite the push for “Made in USA” garments, only 17% of respondents plan to increase sourcing from the U.S. Lu shared his findings in the following Q&A: What surprised you about the survey results? Two things surprised me. First, contrary to common perception, the results do not indicate that the tariff policy so far has effectively supported or encouraged more textile and apparel production in the U.S. This actually makes sense. U.S. mills are as uncertain about the tariff rates as our trading partners are. A U.S. company may manufacture the clothes here, but use yarns, fabrics and zippers from other countries. When tariffs drive up the cost of these raw materials, it reduces the price competitiveness of apparel “Made in the USA.” Many domestic factories are in a “wait and see” mode, holding back on making critical investments to expand production due to the lack of a clear policy signal. Second, I was struck by the wide-ranging impact of the tariffs, which has gone far beyond what I originally imagined. Tariffs have not only increased U.S. fashion companies’ sourcing costs but have also affected their product development, shipping and overall supply chain management. Nearly 70% of the survey respondents said they have delayed or canceled some sourcing orders due to tariff hikes. Should consumers be prepared for less variety in clothing or shortages? Later this year, we may see fewer clothing items from our favorite brands on store shelves — especially during the holiday shopping season — and many of those items may come with a higher price tag. That said, fashion companies are doing what they can to avoid passing on tariff costs across the board, as they recognize that consumers are price sensitive. Many surveyed U.S. fashion companies say they intend to strengthen relationships with key vendors as a strategic move, and there is a growing public call for U.S. companies to provide more support and resources to their suppliers in developing countries. Sustainability is a huge issue in the fashion industry, as millions of tons of textiles end up in landfills every year. Companies say they are spending less on sustainability efforts. What would you tell companies about their sustainability efforts? Our survey suggests that sustainability can open up new business opportunities for U.S. fashion companies. Respondents said that when sourcing clothing made from sustainable fibers — like recycled, organic, biodegradable and regenerative materials — they are more likely to rely on a U.S. sourcing base or suppliers in the Western Hemisphere. In other words, even if apparel “Made in the USA” or nearby cannot always compete on price with lower-cost Asian suppliers, there is a better chance to compete on sustainability. Based on what I’ve learned from our Gen Z students — who expect better quality and more sustainable products if they have to pay more, and are critical consumers for many brands and retailers — it is unwise to hold back on investments in sustainability. What do you see as the biggest takeaway from the survey? One key takeaway is that the $4 trillion fashion and apparel business today is truly “made anywhere in the world and sold anywhere in the world.” In such a highly global and interconnected industry, everyone is a stakeholder — meaning there are no real winners in a tariff war. The study is also a powerful reminder that fashion is far more than just creating stylish clothing. Today’s fashion industry is deeply intertwined with sustainability, international relations, trade policy and technology. I hope the findings will be timely, informative and useful to fashion companies, policymakers, suppliers and fellow researchers. I plan to incorporate the insights, as well as the valuable industry connections developed through my long term partnership with USFIA, in my classroom, giving UD students fresh, real-world perspectives on the often “unfashionable” but essential side of the industry.

Hiring Gen Z: What employers keep getting wrong

As with any new generation entering the workforce, Gen Z possesses unique tools and strengths but also experiences challenges trying to land that first job where Millennials, Gen X-ers and Baby Boomers are doing the hiring. University of Delaware career expert Jill Gugino Panté can talk about how employers can address gaps in the hiring process and communication issues as they relate to a generation that prioritizes work with purpose, authentic connections and work-life balance. Panté, director of the Lerner Career Services Center at the University of Delaware, pointed to the following three areas that should be prioritized: • Transparency. Gen Z wants to feel special and appreciates individual attention, Panté said. Employers should make the hiring process transparent and respond to emails. During busy times, they should use an out of office message that states when they will respond. • Clarity. Make details about salary, benefits, flexibility, skill building and career advancement clear. These details should be on a company's careers page so that candidates have a good understanding of what they can expect. Clarity in job postings is also important: It doesn’t make sense that an entry level position requires more than two years of experience. Don’t call it entry level if it’s not entry level. • Communication mistakes. Be transparent with Gen Z candidates about the process and timeline. More importantly, stick to that process. If a change is made, they should communicate it immediately. Also, employers should be authentic in their communication. If the process is taking longer than expected or they haven’t communicated effectively, employers should acknowledge it instead of continuing to ghost applicants.
