1. Mississippi State University Extension, “How Much Meat to Expect from a Beef Animal: Farm-Direct Beef.” Worked example: 1,200 lb steer, 63% dressing, 4% cooler shrink, ~470 lb freezer-ready beef; also provides freezer-ready percentages by primal/subprimal. https://extension.msstate.edu/publications/how-much-meat-expect-beef-animal-farm-direct-beef

1. Penn State Extension, “Understanding Beef Carcass Yields and Losses During Processing.” Dressing and boneless/bone-in yield vary materially with carcass type, yield grade and fabrication. https://extension.psu.edu/understanding-beef-carcass-yields-and-losses-during-processing

1. Oklahoma State University Extension, “Buying Beef for Home Freezers.” Useful rule-of-thumb framing: carcass product mix depends heavily on cutting instructions; ground/stew is not an automatic residual. https://extension.okstate.edu/fact-sheets/buying-beef-for-home-freezers

1. Oklahoma State University Extension, “Custom Beef Processing: Expected Yields.” Aging and fabrication can produce wide finished-product yield ranges. https://extension.okstate.edu/fact-sheets/custom-beef-processing-expected-yields

• Danish Crown, Afregning. Used to confirm linear weight settlement and classification mechanics.
• Danish Crown, May 22 2026 market update. Used as context that 2025 had historically high cattle-owner settlement and that 2026 remains a competitive cattle market despite softer beef demand.

v1.5 — Danish mobile food operation

• Danish Veterinary and Food Administration / Styrelsen for Fødevarer, Landbrug og Fiskeri: Foodtruck og madbod: Regler for salg af fødevarer. Current guidance: recurring foodtruck/market-food activity above the minor-activity threshold is registered; guidance covers self-control, hygiene, cleaning, layout, temperature handling and transport.
• Danish Food Authority, Authorisation Guidance §15.4: mobile or temporary retail food premises such as foodtrucks are registered; there is no requirement that a mobile unit move at regular intervals. A mobile unit is registered with a home address.

v1.6 — food-safety process anchors

• Danish Veterinary and Food Administration / Fødevarestyrelsen: STEC in food. Notes that undercooked minced beef is an important infection source because contamination can be distributed during mincing.
• Fødevarestyrelsen: Guidance on resistant bacteria in meat / kitchen hygiene. Recommends minced meat be thoroughly cooked.
• Fødevarestyrelsen Hygiejnevejledningen §27: heat treatment and hot holding; restaurant treatment of minced beef is specifically addressed.
• Fødevarestyrelsen SiTTi — Varmholdelse: current time/temperature documentation tool; as of the current guidance it states constant holding at >=56°C has no time restriction in the tool, while other combinations require documentation. This is a safety reference only; 100 Burger a Day uses a separate, shorter sensory-quality cap.

v1.9 — commercial equipment capacity sanity check

Primary manufacturer references reviewed 2026-08-09:

• Frymaster RE80 product page: manufacturer states up to 84 lb French fries/hour for RE80 high-efficiency electric fryers.
• Frymaster Energy Star fryer comparison: lists multiple fryer models around 58–84 lb French fries/hour depending model.
• Garland Master Series / Cuisine production griddle pages: heavy-duty griddles available from 24 in width upward with thick steel plates.
• Garland INSTINCT Griddle 10: 618 × 577 mm cooking surface, two 5 kW zones.

These are used only to test whether 100BAD's required capacity is unusual. They are not procurement recommendations and do not replace a Denmark/EU equipment, electrical, ventilation or certification review.
