# A decade of label modernisation: AAFCO PFLM and the FEDIAF nutrient tables

Two institutions, an ocean apart, spent the last decade rewriting what a pet-food label is allowed to say. In the United States, AAFCO ran a multi-year effort — the Pet Food Label Modernization (PFLM) — that started in 2015 and was adopted into the 2024 Official Publication. In Europe, FEDIAF publishes a fresh set of nutrient guidelines almost every year, each one a snapshot of the minimum recommended levels for complete dog and cat food. This article walks both timelines side by side, and shows how they converged on the same consumer-facing idea: a label that reads more like a human "Nutrition Facts" box.

## AAFCO: from a 1970s rule to a 2024 regulation set

The Pet Food Committee's own mission, per `AAFCO_PET_FOOD_COMMITTEE_ROLE`, is "To provide a forum for regulators, industry, and other stakeholders to monitor, review, and recommend appropriate revisions to the AAFCO Official Publication as related to pet food and specialty pet food in order to protect pet and human health and to promote a structure for orderly commerce within the industry." The PFLM project that consumed the committee for eight years is dated precisely in `AAFCO_PFLM_PROJECT`: "In 2015, AAFCO began the Pet Food Label Modernization (PFLM) project to modernize and update the model regulations that set the requirements for pet food labeling." The stated goal was "to provide consumers and regulators with labeling information that is transparent, easy to understand, and in a format more familiar," and AAFCO "recommends a transition period of six years for manufacturers to fully incorporate the label and packaging changes."

The reform did not appear overnight. `AAFCO_2019_pfc_midyear_decisions` records the seed meeting — the Pet Food Committee Midyear in Savannah, Georgia, on January 22, 2019 — where the committee "Strike[s] PF3(e)" (the long-standing "95% claims" rule dating to the 1970s/80s) and revises "PF4(g) (Feeding directions)," and where "Kristen Green (KY) and Stan Cook (MO)" stepped down as chair/vice-chair in favour of "Lizette Beckman (WA) and Jason Schmidt (LA)." `AAFCO_2019_to_2023_committee_decisions_summary` folds this into the broader arc: 2019 PFC sets PF3(e) strike + PF4(g); 2020 MBRC drafts PF3/PF5/PF7.

That 2020 drafting step is `AAFCO_2020_mbrc_midyear_decisions`: the Model Bills and Regulations Committee (MBRC), at its January 21, 2020 Albuquerque meeting, made "Five Regulatory Revision Recommendations" including "Revise Regulation PF3 — Brand and Product Names," "Revise Regulation PF5 — Ingredients," and "Revise Regulation PF7 — Nutritional Adequacy and Feeding Protocols" — the earliest formal attachment of the modern PF sections.

By 2021 the draft was open to the public. `AAFCO_2021_annual_pflm_public_comment` records the August 2, 2021 Annual Meeting where "PFLM Working groups draft model regulations are available on the AAFCO/PFC website (posted in July) and are available for public comment" over "the 90-day comment period," with "PFLM WG hope to send recommendations to PFC in November, 2021." It also launched a Human Grade Working Group and a Copper Working Group.

The first consolidated draft landed on September 28, 2022. `AAFCO_2022_pflm_first_draft` (editor Lizette Beckman) carries "PF1 — Definitions and Terms (11 definitions)" and the now-famous "PF74. Intended Use and Nutritional Adequacy Claims ← numbering typo." The final draft on April 3, 2023 (`AAFCO_2023_pflm_final`) fixed that: "PF74 → PF4 (numbering fixed)" and added a brand-new concept, "Familiar Household Unit," defined as "a typical feeding unit in volume or count (e.g., can, measuring cup, treat, or piece)." PF9 was narrowed to "Determination of Calorie Content for Dog and Cat Foods." The 2023 Annual Meeting in Baltimore (July 31 – August 2, 2023) adopted it: `AAFCO_2023_annual_meeting_pflm_adoption` notes the new Model Regulations were embedded as "Appendix A (pages 23-69)" and "approved by AAFCO membership for inclusion in the **2024 AAFCO Official Publication**."

The 2024 result, per `AAFCO_2024_model_regulations_overview`, is "Regulations PF1 through PF12" — most importantly PF5 "Pet and Specialty Pet Nutrition Facts (the boxed panel with calorie content per familiar household unit and ordered nutrient guarantees)" and PF9 "Determination of Calorie Content (Modified Atwater formula ... kcal/kg)." Crucially, `AAFCO_2024_official_publication_summary` states the nutrient profiles "carry forward the values last substantively updated in 2014/2016 — ... the 2024 edition is explicitly a 'carry-over of 2016 revisions'," so "No new numeric nutrient profile values were introduced in 2024." The institution around it, from `AAFCO_OFFICIAL_PUBLICATION`, retains "current and previous versions of the AAFCO OP" in the Feed BIN Library and launched an AI assistant, "AVA," in 2026 — while prohibiting OP use "as training data for artificial intelligence purposes without authorization."

## FEDIAF: a new guideline edition almost every year

Where AAFCO revises rarely, FEDIAF republishes continuously. The cat adult-maintenance table (Table III-4a) is reproduced first-hand for four editions in this repository. `fediaf_historical_2021_cat_adult_maintenance` (Publication October 2021) lists "Taurine (canned pet food)* g 0.27 0.20" and "Taurine (dry pet food)* g 0.13 0.10," with "Protein* g 33.30 25.00." `fediaf_historical_2022_cat_adult_maintenance` carries the identical rows. `fediaf_historical_2024_cat_adult_maintenance` (Publication July 2024) is again unchanged — same "Taurine (canned pet food)* g 0.27 0.20 / Taurine (dry pet food)* g 0.13 0.10." And `fediaf_historical_2025_cat_adult_maintenance` (Publication September 2025) repeats them once more. Four consecutive guideline editions, identical cat taurine rows.

The dog adult-maintenance table (Table III-3a) is equally well covered: `fediaf_historical_2021_dog_adult_maintenance` opens with "Protein* g 21.00 18.00 25.00 20.00," and the 2022, 2024 and 2025 editions (`fediaf_historical_2022_dog_adult_maintenance`, `fediaf_historical_2024_dog_adult_maintenance`, `fediaf_historical_2025_dog_adult_maintenance`) each reproduce their year's minimum recommended levels, all C1-verified.

**Honest gap:** four other FEDIAF editions are placeholders, not data. `fediaf_historical_2018_pending`, `fediaf_historical_2019_pending`, `fediaf_historical_2020_pending` and `fediaf_historical_2023_pending` are each explicitly "PENDING: first-hand source unavailable." Their retrieval findings are unambiguous: the official European Pet Food media library "lists full guideline PDFs only for **2021, 2024 and 2025**; 2020 exists only as a title-page JPG ... **2018, 2019 and 2023 are absent**," and the Wayback Machine was unreachable. Per the project's no-fabrication rule, "the 2018/2019/2023 adult-maintenance nutrient tables are **NOT reproduced**." So the FEDIAF timeline here spans 2021 → 2022 → 2024 → 2025 with real values, and 2018/2019/2020/2023 are flagged as missing — no numbers are invented for them.

## How the two timelines meet on the label

The processing logic behind FEDIAF's numbers is spelled out in `FEDIAF_2025_wet_vs_dry_processing`: taurine bioavailability "is lower when cats are fed heat-treated canned food," so "a heat-processed wet cat food needs to contain approximately 2 to 2.5 times more taurine than a dry extruded food, which should contain 0.1% DM taurine." The "late-1980s link between commercial heat-processed cat foods and taurine-deficiency dilated cardiomyopathy (Pion P et al. 1987) drove these fortification rules." FEDIAF's own labeling guidance, `FEDIAF_labeling_format`, sits "inside the Nutritional Guidelines and leans on Regulation (EC) No 767/2009" — complete pet food must carry "feeding directions indicating the purpose for which the food is intended," with energy calculated via "Weende analysis" and "declared-value tolerances per ANNEX 4 of Regulation 767/2009."

That is the same consumer-facing instinct AAFCO built into PF5: a boxed nutrient panel with calorie content per familiar household unit. AAFCO reached it through a committee-driven, eight-year, state-adopted regulation set; FEDIAF reaches it through annual trade-guideline editions that are recommendatory, not statutory. Both end at the same place — a label that states "complete and balanced," lists nutrients per unit, and tells the owner how much to feed.
