New Report Finds Industrially Produced Meat and Cheese Dominate America’s School Lunch Entrées, Raising Concerns for Children’s Health  

Analysis of more than 10,000 entrées finds widespread red and processed meat linked to cancer, limited protein diversity, and other health concerns associated with commonly served products; report identifies policy solutions to support healthier school meals

Washington, D.C. – A new report by Friends of the Earth and Chef Ann Foundation finds school lunch entrées are dominated by processed, meat- and cheese-laden foods sourced from large-scale industrial supply chains, increasing children’s exposure to known carcinogens and ingredients of concern, and potentially to undisclosed contaminants including veterinary drug, dioxin, and pesticide residues. 

Beyond the Nugget: The Hidden Health Risks of Industrially Produced Animal Proteins—and the Path Toward Better School Lunches analyzed more than 10,000 lunch entrées from 45 public school districts nationwide and assessed representative products from 10 of the most commonly offered entrée categories offered by USDA-approved processors. The findings reveal how federal policy has driven a school food system heavily reliant on industrially produced, often-processed meat and cheese entreés that are associated with chronic disease risks. 

Key findings include:

• Animal protein dominates school lunch menus. 88% of entrées contained animal products as the primary protein source. 53% contained dairy, and 47% contained cheese. Excluding nut butter and jelly sandwiches, only 5% of entrées were fully plant-based.
• Processed and red meats are widespread in school meals. Breaded chicken products, including chicken nuggets and patties, were the single most frequently served entrée category, appearing on more than half of school days. Overall, 39% of entrées contained either red or processed meat: at least 28% contained processed meat, and 27% contained red meat. 
• Representative products raise multiple health concerns. Among the 10 representative products of most commonly served entreés profiled in the report, seven contained processed meat; seven contained sodium or potassium phosphates; seven exceeded 400 mg of sodium; and seven contained added sugars. Four contained sodium nitrate or nitrite, three contained red meat, and six were from vendors identified as having significant USDA food safety recalls within the past five years, including recalls involving foreign matter contamination, Listeria, and Salmonella.

“Chicken nuggets shouldn’t be the defining protein of the American school lunch,” said Chloë Waterman, deputy director at Friends of the Earth and a co-author of the report. “Schools are being asked to serve healthier food while operating within a system that continues to steer them toward industrially produced meat and cheese entrees. We have an opportunity to change that by giving schools the resources they need to phase out processed meat, diversify protein choices, and procure and cook healthier food.”

Health concerns go beyond the nutrition label

The prevalence of processed meat and cheese in school meals raises significant health concerns for the nearly 30 million children who participate in the National School Lunch Program. 

Diets high in red and processed meats are associated with increased risks of cardiovascular disease, type 2 diabetes, and certain cancers. Processed meat is classified as a known carcinogen to humans, while red meat itself, as well as sodium nitrates and nitrites often found in processed meats, is classified as a probable carcinogen. The report also highlights children’s potential exposure to contaminants not disclosed on labels, including veterinary drug and pesticide residues, PFAS, dioxins, and heavy metals, by consuming foods containing industrially produced animal proteins. 

“Federally funded school meals must support children’s health, not routinely include foods known to increase the risk of cancer and chronic disease,” said Roopa Kalyanaraman Marcello, DrPH, MPH, the report’s lead author. “The overlap of multiple known and potential risks present in school lunches—which millions of American children rely on over many years of critical growth and development—is a significant yet preventable public health threat. The food served to children in schools must be held to a higher standard.”

Federal policies drive reliance on industrially produced, processed meat and cheese

The report finds that federal school meal policies and funding structures make processed meat and cheese products among the easiest to serve. The report emphasizes that these findings are not a criticism of school nutrition professionals, many of whom are finding creative ways to serve healthier entrees despite significant constraints. A companion resource, Building a Better Lunch Tray, showcases school districts leading the way toward healthier meals. The report identifies policy reforms that could help more districts follow their lead by reducing barriers to scratch cooking, improving ingredient quality, and diversifying the proteins served on school lunch trays. 

Schools receive approximately $4.70 in federal reimbursement for each meal—funding that must cover food, labor, equipment, transportation, and administrative costs. Schools also receive USDA Foods entitlement funds that can be used to obtain federally purchased foods, but options for higher-quality sourcing are limited. Approximately 40% of USDA Foods entitlement spending goes toward processing commodities such as chicken, beef, and cheese into ready-to-serve products like nuggets, patties, and pizza. Together with persistent workforce shortages and outdated kitchen infrastructure, these policies create a system in which industrially produced, processed, ready-to-serve foods are often easier to procure and prepare than scratch-cooked meals featuring a wider variety of proteins and higher-quality ingredients. 

“The science tells us what to do; now we need to make sure all schools have the resources to scratch cook,” said Mara Fleishman, CEO of Chef Ann Foundation. “School nutrition professionals are already working wonders on tight budgets and outdated kitchens. What they need now are policies that make scratch cooking with cleaner, higher-quality ingredients the easy choice in every school, not the expensive exception.”

A roadmap toward better school meals

The report outlines three complementary policy priorities for modernizing school meal funding, procurement and nutrition standards to better support children’s health:

1. Invest in schools’ capacity to serve scratch-cooked meals with high quality ingredients by increasing federal meal reimbursement rates, supporting investments in kitchen infrastructure and workforce development, and expanding farm-to-school programs.
2. Strengthen school nutrition standards to reflect current science by phasing out processed meats and other ingredients of concern; increasing plant protein offerings to diversify protein sources and increase fiber; and continuing to reduce saturated fat, sodium, and sugar.
3. Reform USDA commodity procurement by excluding processed meats and other ingredients of concern from the USDA Foods Commodity Program; phasing out animal products from supply chains that routinely use antibiotics and growth-promoting drugs; setting targets for sourcing third-party-certified products, including USDA Organic; and giving schools flexibility to spend entitlement funds on local, minimally processed foods.

“As a single mother of three, I am grateful for the school meals my children receive, and I want to trust that those meals are nourishing them,” said Noelle Nyrens, a parent in Iowa City, IA. “My youngest daughter has Type 1 Diabetes and Celiac Disease and eats plant-based, so the importance of good nutrition is deeply personal to our family. I know firsthand how challenging it can be to provide quality food on a limited budget, but what we feed our children today will shape their health for years to come. Schools need the resources to serve more fresh, whole foods and diverse, high-quality proteins, and parents should have a voice in the decisions that shape what goes on our children’s plates.” 

About the report

Beyond the Nugget: The Hidden Health Risks of Industrially Produced Animal Proteins—and the Path Toward Better School Lunches examines the foods most commonly served in U.S. school lunches and the health risks associated with highly processed, meat- and cheese-centered entrées. Researchers reviewed 10,226 identifiable lunch entrées from 45 K–12 public school districts nationwide, including large, medium, and small districts, to identify the most frequently served entrée categories and assess the prevalence of red meat, processed meat, dairy, plant-based entrées, and overall protein diversity.

Because publicly available school menus generally do not identify the specific products or ingredients used to prepare meals, researchers selected representative products for 10 of the most commonly offered entrée categories from companies participating in USDA’s National Processing Agreement Program. Each product was evaluated based on its labeled ingredients and nutrition facts, documented food safety concerns associated with its vendor, and a review of scientific literature, federal monitoring and independent testing related to potential undisclosed contaminants and chronic disease risks.
