How to Talk About Recalls and Contamination in Japanese: Public Health Warnings
Learn to report food recalls, contamination, and public health alerts in Japanese using 回収, 汚染, 自主回収, and the 〜が確認されました pattern.
By MarcusFood & cafés · Yapr Learn
When a food product is recalled or contaminated, Japanese news and official notices use a specific set of terms that differ from allergy vocabulary. This lesson teaches you to understand and produce public health announcements: how to say a product is being recalled, that contamination was detected, and that the manufacturer is voluntarily collecting items. You will learn the key nouns 回収 (kaishū, recall/collection), 汚染 (osen, contamination), and 自主回収 (jishu kaishū, voluntary recall), plus the passive and 〜が確認されました patterns that appear in official notices. These expressions are about protecting the public, not about individual allergic reactions, so the focus stays on products, batches, and official action.
By the end, you can…
- report that a food product is being recalled using 回収 and 自主回収.
- say that contamination was detected or confirmed in a product or batch.
- understand and produce a short public health warning about a recalled item.
Listen once. Try it slowly. Then say it without looking.

この商品は回収されました。
This product has been recalled.
Kono shōhin wa kaishū saremashita.
Standard passive form used in news and official notices to state that a product was collected from stores.
自主回収を行っています。
We are carrying out a voluntary recall.
Jishu kaishū o okonatte imasu.
Used by manufacturers and retailers when they recall products on their own initiative, not by government order.
食品から異物が確認されました。
A foreign object was confirmed in the food.
Shokuhin kara ibutsu ga kakunin saremashita.
〜が確認されました is the standard official phrasing for 'was confirmed/detected' in public health reports.
細菌による汚染の恐れがあります。
There is a risk of bacterial contamination.
Saikin ni yoru osen no osore ga arimasu.
〜の恐れがあります expresses a potential risk, common in cautious official warnings.
対象のロット番号をお知らせください。
Please tell us the lot number of the affected product.
Taishō no rotto bangō o oshirase kudasai.
Used when a store or hotline asks customers to identify the affected batch; ロット番号 is the standard term.
Pronunciation guides are approximate. Slow playback keeps the original pitch.
Make it make sense
Useful pattern
The core pattern for public health announcements is [product] は回収されました (was recalled) and [substance] が確認されました (was confirmed/detected). For example, この飲料は回収されました (This beverage was recalled) and 異物が確認されました (A foreign object was confirmed). To describe an ongoing action, use 自主回収を行っています (We are conducting a voluntary recall). Note that 汚染 (contamination) is a noun; to say 'contaminated,' use 汚染された or 汚染の恐れがある (there is a risk of contamination).
When to use it
Use these expressions when reading or writing official notices, store signs, or news about food safety. 回収 is neutral and factual, suitable for headlines and announcements. 自主回収 specifically means the company chose to recall the product voluntarily, often before a government order. 〜の恐れがあります is more cautious than 〜があります; it signals a possible but not yet confirmed risk. In customer service, say お客様, 対象商品は回収されましたので、ご返金いたします (The affected product has been recalled, so we will refund you).
Listen to each line, then take one part and reply out loud.
昨日のニュースで、この乳製品が自主回収されたと聞きました。
I heard on yesterday's news that this dairy product was voluntarily recalled.Kinō no nyūsu de, kono nyūseihin ga jishu kaishū sareta to kikimashita.はい、細菌による汚染の恐れがあるそうです。
Yes, apparently there is a risk of bacterial contamination.Hai, saikin ni yoru osen no osore ga aru sō desu.対象のロット番号はどこに書いてありますか。
Where is the affected lot number written?Taishō no rotto bangō wa doko ni kaite arimasu ka.パッケージの裏側に記載されています。店に持って行けば返金してもらえます。
It is printed on the back of the package. If you take it to the store, you can get a refund.Pakkēji no uragawa ni kisai sarete imasu. Mise ni motte ikeba henkin shite moraemasu.A little context goes a long way
Japanese recall notices often use formal passive and keigo phrasing, even on supermarket signs, because the text is issued by a company to the public. 自主回収 is preferred over 回収 alone when the company acts voluntarily, as this signals responsibility. When speaking to staff, using 〜そうです (I heard that...) softens a claim you read in the news and avoids sounding like you are accusing the store.
One thing to watch for
Using アレルギー (allergy) to describe a contamination or recall, as in この食品はアレルギーです.
Try this instead: Allergy vocabulary describes a person's reaction, not a product problem. For public health, say この食品は回収されました (This food was recalled) or 汚染が確認されました (Contamination was confirmed). Reserve アレルギー for personal conditions such as 私は卵アレルギーがあります (I have an egg allergy).
Your turn
Try answering out loud before checking a possible answer.
1How would you say 'A foreign object was confirmed in this product' in an official notice?
Show a sample answer
この商品から異物が確認されました。
This uses the standard passive 確認されました with から marking the source. この商品に異物が確認されました is also acceptable, but から is common when the object came from the product.
2A company recalls a product on its own before any government order. Which term fits best: 回収 or 自主回収?
Show a sample answer
自主回収
自主回収 emphasizes that the company acted voluntarily. 回収 alone is not wrong, but it does not convey the voluntary nature that Japanese notices often highlight.
3Translate: 'There is a risk of contamination.'
Show a sample answer
汚染の恐れがあります。
〜の恐れがあります expresses a possible risk. 汚染の可能性があります is also correct and slightly more neutral, while 恐れ is more cautious and formal.
For recalls and contamination, use 回収されました for 'was recalled,' 自主回収 for voluntary recalls, and 〜が確認されました for 'was confirmed.' Keep allergy terms for personal reactions, not public health notices.
