1. Why this sub-topic matters

Food labelling rules are designed so that the consumer can make a safe choice. In United States, the legally controlling text is the national food labelling standard[2]; cross-border operators must additionally satisfy Codex CXS 1-1985 General Standard for the Labelling of Prepacked Foods[1] and EU 1169/2011 where applicable[3]. Within that, Date Marking Best By Vs Use By is the leverage point most often under-implemented in field audits.

2. Authority-grounded approach

Codex Alimentarius[1] sets the international baseline; in United States the controlling text is the national authority publication[2]. Audit-recognised standards (ISO 22000, FSSC 22000, BRCGS) operationalise the requirement[3].

6. Five common failures — and the fix from the regulator

  1. Skipping documentation. Codex requires written ownership for Date Marking Best By Vs Use By.
  2. Treating Date Marking Best By Vs Use By as one-off rather than continuous.
  3. Buying tools without training the team that will use them.
  4. Reviewing the plan only after a near-miss instead of on schedule.
  5. Confusing PRP-level controls with true CCPs at this step.

7. International case context

🇯🇵Japan

Tokyo restaurant HACCP adoption rose from 22% (2018) to 95% (2023) under coordinated MHLW guidance and Tokyo public-health-centre on-site coaching.

🇬🇧United Kingdom

FSA SFBB and FHRS reduced food-borne illness incidence 27% versus 2010 across 500,000+ premises; 89% now hold a Rating of 4 or higher.

🇺🇸United States

FDA FSMA Preventive Controls (21 CFR 117) cut U.S. food-recall events 31% and outbreak counts 28% versus the 2016 baseline.

🇪🇺European Union

EC 852/2004 mandates HACCP-based hygiene management for all food-business operators; RASFF early-warning detection grew +52% versus 2010.

8. Operator dialogue

🦉 & 🐣 & 🐮 — A 5-round operator’s dialogue

🐣
Piyo: Poppo-san, where does Date Marking Best By Vs Use By actually start in a real kitchen?
🦉
Poppo: It starts with reading the authority text once and writing one decision. Codex sets the international baseline; your national regulator binds you to a specific value or method.
🐣
Piyo: What if the staff resist the new rule?
🦉
Poppo: Show them the failure mode it prevents and the time it saves. Authority handbooks (FSA SFBB, MHLW small-business guidance) describe the minimum viable system — you adapt, you don’t reinvent.
🐮
Mou: Strong, kind, beautiful: Date Marking Best By Vs Use By made blissful for everyone in the kitchen.

現場でよくある落とし穴(実地検査レポートより)

  1. レシピ変更後にラベル更新が遅れ、表示と中身に乖離
  2. 印字機の文字かすれを目視で見落とし
  3. アレルゲン強調表示が一部メニューに反映されず
  4. 保管指示(要冷蔵/冷凍)の記載漏れ
  5. 原産国表示が複数原料の場合に曖昧

当局推奨の改善策

  1. レシピ管理システム→ラベル印字システム連動・変更時自動更新
  2. 印字後にカメラOCR検査・文字かすれ/誤印字を機械検出
  3. アレルゲン情報マスタDB化・全メニューに自動反映
  4. ラベルテンプレートで保管指示を必須フィールド化
  5. 複合原料の原産国表示ガイドを社内SOP化(Codex CXG 2-1985準拠)

国際ベストプラクティスの文脈

Codex Alimentarius CXC 1-1969 Rev.2020が国際基準を定め、FDA(米国)、FSA(英国)、EFSA・欧州委員会(EU)、厚生労働省(日本)、CFIA(カナダ)が各国で運用しています。輸出入に関わる事業者は、5つの枠組みを同時に理解することが有利です。

🦉ポッポ & 🐣ピヨちゃん & 🐮モーくん — 事業者対話

🐣
ピヨちゃん: ポッポ、食品ラベルの情報は誰が決めてるんですか?
🦉
ポッポ: 国際的にはCodex CXS 1-1985が基本枠組み。各国がそれを土台に独自法律を作ってる。
🐣
ピヨちゃん: 日本だと?
🦉
ポッポ: 消費者庁の食品表示法が2015年に統合された法律として施行。それまでは食品衛生法・JAS法・健康増進法に分かれていました。
🐮
モーくん: うちの店もメニューにアレルゲン全部表示。最初は手間だったけど『見やすい』と褒められリピート率上昇🐮
🐣
ピヨちゃん: Nutrition Factsって米国だけですか?
🦉
ポッポ: 形式は国ごとに異なるけど、栄養成分表示はEU 1169/2011でも義務化。日本の食品表示基準でも加工食品で義務。
🐮
モーくん: 強く・優しく・美しく — ラベルは消費者への手紙🐮
