ホーチミン市で汚染フォー麺2,800トン製造の夫婦逮捕|約12年間で被害規模が判明
2026年4月26日、ホーチミン市警察はタンタオ区（Tan Tao Ward）で長年にわたり違法な化学物質を混入した生フォー麺を製造・出荷していた44歳の夫婦、Nguyen Thi My Phung容疑者とPham Tuan Thanh容疑者を食品安全規定違反の容疑で身柄拘束し、検察送致しました。捜査当局の発表によると、2014年頃から約12年間で生産された汚染麺の総量は2,800トンに達し、ベトナム国内の食品安全事件としては過去最大級の規模となります。
A search was conducted on April 16, and about 700 kg of fresh noodles, 10.2 kg of borax, 27 plastic cans containing liquid glass (sodium silicate), and 10 liters of a yellow liquid were seized at the scene. Police announced that "the couple deliberately mixed in banned chemicals to improve texture, prevent the noodles from breaking apart, and extend the shelf life from a few hours to up to two days."
We have organized how the fresh noodles for pho (Phở) and bun cha (Bún Chả) that Japanese tourists eat in Ho Chi Minh City are distributed, how local Vietnamese are reacting, and what criteria to use to eat safely.

Physical evidence seized
- Fresh pho noodles: about 700 kg
- Borax: 10.2 kg
- Sodium silicate (liquid glass): 27 plastic cans
- Yellow liquid of unknown use: 10 liters
Police believe the noodles were traded for years at a wholesale price of 10,000-15,000 VND per kg (about 60-90 yen, at 1 yen = 170 VND), and announced they would expand the investigation to retailers and eateries along the distribution route.
Background | Why borax contamination keeps recurring in Vietnam
Vietnam's Ministry of Health bans the use of borax and boric acid in food entirely, but their illegal use in fresh noodles, Vietnamese fried spring roll wrappers (banh trang), and minced-fish products (gio) has been repeatedly uncovered over the past 20-plus years. A past investigation by Saigoneer reported that the carcinogenic fluorescent whitening agent Tinopal was detected in 75% of pho noodle samples circulating in Ho Chi Minh City.
Why illegal additives persist
| Factor | Details |
|---|---|
| Economic incentive | Because borax extends shelf life from a few hours to 48 hours, waste loss drops sharply |
| Limits of the inspection system | Regular inspections cannot keep up with the thousands of tiny noodle-making shops nationwide |
| Price competition | Fresh noodles are cheap, around 10,000 VND per kg, and are chosen on price over quality |
| Lack of awareness | Both eatery owners and consumers tend to mistake "glossy noodles" for "fresh" |
The effects of borax and liquid glass on the human body
According to public materials from Vietnam's National Institute for Food Control (NIFC), even small amounts of borax cause chronic poisoning of the digestive system, liver, kidneys, and brain with long-term intake. Ingesting 5 g or more at once is said to produce acute poisoning symptoms such as nausea, vomiting, bloody stool, convulsions, and shock within 6-8 hours.
Liquid glass (sodium silicate) is a strongly alkaline agent used as an industrial adhesive and preservative, and it is a completely unapproved substance for food hygiene.
By the numbers | Food safety enforcement cases in Ho Chi Minh City
We have organized public data from Ho Chi Minh City's Food Safety Management Committee.
| Year | Number of cases | Main violations | Administrative penalties (VND) |
|---|---|---|---|
| 2023 | 2,847 cases | Additives / labeling fraud | About 8.7 billion VND |
| 2024 | 3,156 cases | Unlicensed production / additives | About 9.4 billion VND |
| 2025 | 3,402 cases | Additives / hygiene management | About 10.8 billion VND |
| 2026 (Jan-Apr) | 1,287 cases | Borax, Tinopal, and others | About 4.2 billion VND |
Converting at 1 USD = 25,500 VND and 1 JPY = 170 VND, the full-year 2025 penalty total is about 63.53 million yen (about 424,000 USD). This pho case stands out in both scale and duration, and local paper Tuoi Tre reports it is likely to result in one of the largest criminal penalties ever for a single case.
Local reaction | Voices of Vietnamese users
After the news broke, we excerpt three anonymized, paraphrased voices from the comment sections of Tuoi Tre Online and VnExpress, and from the Vietnamese-language X (formerly Twitter) community.
Comment 1 (30s, Ho Chi Minh resident, homemaker)
"2,800 tons — that's far more than my whole family ate over 10 years. As someone who has cooked meals for my kids, it makes me sick. From now on I'll only buy noodles that are in clear packaging with the production date clearly marked."
Comment 2 (40s, Tan Tao Ward restaurant owner)
"I had no idea there was a factory in my neighborhood. Local eateries need to review all their suppliers. This isn't an individual problem — it's a trust issue for the whole industry."
Comment 3 (20s, university student, Hanoi)
"Food culture differs between north and south, but I never imagined Ho Chi Minh's pho noodles were in this state. I feel sorry for the tourists. I agree with those who say it should be a life sentence, not just a fine."
While voices supporting the Vietnamese police stood out in the comments, the majority called for a fundamental strengthening of oversight of small-scale producers.
Impact on Japanese tourists | Criteria for eating safely
We lay out what to watch for when Japanese eat pho or bun cha in Ho Chi Minh City.
How to spot a safe shop
| Item to check | Safety | Note |
|---|---|---|
| Noodle color | A natural white with a slightly yellow tint | Unnaturally white with strong translucence |
| Texture | Somewhat easy to break and soft | Strongly springy, doesn't break at all even when chewed |
| Production-date labeling | Same-day production is clearly marked | No labeling; keeps for several days |
| Shop size | Chain, famous, or mid-tier shop | Nameless street stall |
| Price range | 50,000-80,000 VND per bowl | 20,000 VND or less per bowl |
Converting prices to JPY, 50,000 VND ≈ about 294 yen and 80,000 VND ≈ about 470 yen. If you prioritize safety, it's realistic to choose a mid-tier restaurant geared toward tourists (seeRecommended cafés and restaurants in District 1, Ho Chi Minh Cityfor reference).
If you feel unwell
| Contact | Details |
|---|---|
| Japanese Consulate-General in Ho Chi Minh City | +84-28-3933-3510 |
| Family Medical Practice HCM | +84-28-3822-7848 (Japanese available 24 hours) |
| FV Hospital | +84-28-5411-3333 |
Because abdominal pain, vomiting, or bloody stool within 24-48 hours of arrival can overlap with acute symptoms of borax poisoning, seeking care early is recommended.
Industry ripple effects | Impact on Vietnam's food distribution
After the case came to light, the Ho Chi Minh City Food Safety Management Committee announced on April 25 a sweeping inspection of about 400 small noodle-making shops in the city. According to Tuoi Tre, distribution into Long An, Binh Duong, and Dong Nai provinces is also subject to additional investigation.
Anticipated industry changes
- Accelerated shift to major noodle makers: Demand for vacuum-packed noodles from majors such as Vifon and Acecook increases
- Moving up mandatory traceability labeling: Debate over disclosing production sites via QR codes reignites
- Impact on OEM manufacturers: When Japanese food trading firms source locally, the trend to limit dealings to certified factories only expands
For Japanese food importers and OEM operators, reviewing supplier selection criteria becomes urgent. On the site operated by Agriture,Food OEM Gatewaywe provide know-how on selecting manufacturing partners that accounts for such risks.
Practical table | Choosing a shop to enjoy pho safely
We have compiled pho specialty shops that are well regarded by Japanese tourists in Ho Chi Minh City (based on our reporting; prices as of April 2026).
| Store name | Area | Price (VND/JPY) | Characteristics |
|---|---|---|---|
| Pho Hoa Pasteur | Pasteur street, District 3 | 95,000 VND / about 560 yen | Long-established since 1968, house-made noodles |
| Pho Le | Nguyen Trai street, District 5 | 85,000 VND / about 500 yen | A popular shop in the Cho Lon district |
| Pho Quynh | Pham Ngu Lao street, District 1 | 90,000 VND / about 530 yen | Open 24 hours, tourist-friendly |
| Pho 2000 | Le Thanh Ton street, District 1 | 110,000 VND / about 650 yen | The shop visited by former President Clinton |
All of these shops have their own noodle-making lines or contracts with major wholesalers, and have been confirmed to be unrelated to this case.
Summary | Hold to the criterion of avoiding "pho that's too cheap"
The figure of 2,800 tons over 10 years means Ho Chi Minh residents were exposed to illegal additives over a long period. After the Vietnamese police announcement, the market price of fresh noodles has surged from 12,000 VND to 18,000 VND per kg (about 70 yen to about 106 yen), showing signs of a shift toward sound manufacturers.
There are three actions Japanese tourists can take right now.
- Avoid extremely cheap street-stall pho priced at 50,000 VND (about 294 yen) or less per bowl
- If the noodles are unnaturally white or strongly springy, switch to a different dish
- Choose famous shops or chains at mid-tier or above, and give priority to shops using vacuum-packed noodles with a production date marked
In enjoying Vietnam's food culture, this case is a chance to sharpen your "eye for choosing a safe shop." For local Ho Chi Minh City fare beyond pho, seeLocal food information for District 1, Ho Chi Minh Cityfor reference.
