This is Part 9 of the Thai Life and Law series. In Part 8, we covered banking, remittances, and foreign exchange regulations. This time, we look at food safety and consumer protection. When you shop at Thai supermarkets, markets, and street stalls every day, questions arise: “Is this food safe?” “I can’t read the expiry date.” “What if I buy a defective product?” Let’s walk through the legal framework behind your daily shopping.
1. Is Thai Food Safe? — Check for the FDA Mark
The Legal Framework
The legal foundation of food safety in Thailand is the Food Act B.E. 2522 (1979). The FDA (Food and Drug Administration) and MOPH (Ministry of Public Health) are the primary regulators.
Thai food products are classified into four categories by level of regulation:
| Category | Description | Examples |
|---|---|---|
| Specially controlled food | Strictest regulation. FDA registration required | Infant formula, supplements |
| Controlled food | FDA registration required | Certain cooking oils, condiments |
| Standardized food | Quality standards are prescribed | Certain processed foods |
| General food | Labelling obligations apply | Other processed foods |
The “อย.” Mark — Your Safety Indicator
When picking up a packaged food product at a supermarket or convenience store, look for the “อย.” (Aor Yor) mark on the packaging. This indicates the product is registered with the FDA and has met certain safety standards.
All processed foods are required to display an FDA serial number. This applies to imported products as well. Processed foods without the FDA mark may not be legally authorised for sale — it is best to avoid them.
How to Read the FDA Number
The FDA number consists of 13 digits:
| Position | Meaning |
|---|---|
| Digits 1-2 | Province code (location of manufacturing/import facility) |
| Digit 3 | Facility type (1=FDA-licensed manufacturer, 2=provincial manufacturer, 3=FDA-licensed importer, 4=provincial importer) |
| Digits 4-8 | Facility licence number + year of licence |
| Digit 9 | Issuing authority code |
| Digits 10-13 | Product serial number |
You do not need to decode this for every purchase, but confirming that the อย. mark and a 13-digit number are present provides a basic level of assurance.
Healthier Choice Logo
The FDA also certifies a “Healthier Choice” logo. This voluntary programme marks food products with sugar, salt, and fat content below set thresholds.
2. Reading Expiry Dates — Mind the Buddhist Calendar
Thai Buddhist Calendar
The first thing that confuses many foreigners on Thai food labels is the year on the expiry date. Thailand uses the Buddhist Era (BE) calendar.
Thai Buddhist Era = Gregorian year + 543
So “2569” on a label means 2026. Do not panic thinking the product is centuries old.
Date Format
| Thai | Meaning |
|---|---|
| ผลิต (phalit) | Manufacturing date |
| ควรบริโภคก่อน (khuan boriphok kon) | Best Before / Expiry date |
Dates are written in day/month/year order — the reverse of the Japanese format (year/month/day).
Example: “ควรบริโภคก่อน 01/04/2569” = 1 April 2026
3. Street Food and Markets — How Are They Regulated?
Street Vendors Are Exempt from FDA Licensing
Thai street vendors and market stalls do not qualify as “factories” and are therefore not directly subject to the manufacturing licence requirements under the Food Act. However, the food quality and safety standards under Food Act Section 25 apply to all food, including that sold by street vendors.
Hygiene management for street food falls under local government authorities (Bangkok Metropolitan Administration, provincial offices).
The “Clean Food Good Taste” Sticker
The Ministry of Public Health (MOPH) has operated the “Clean Food Good Taste” (อาหารสะอาด รสชาติอร่อย) hygiene certification programme since 1999. Certified stalls and restaurants display a dedicated sticker.
The programme has recently evolved into “SAN Plus”, applying strengthened standards based on four principles: cleaning, cooking, cooling, and contamination prevention.
Uncertified stalls can of course serve excellent food, but the hygiene risk becomes a matter of personal judgement. If you are choosing food for young children, opting for certified establishments may provide added peace of mind.
4. If You Buy a Defective Product — Consumer Protection and Product Liability
Consumer Protection Act
The Consumer Protection Act B.E. 2522 (1979) establishes basic consumer rights. The regulator is the OCPB (Office of the Consumer Protection Board).
| Consumer Right | Description |
|---|---|
| Right to safe products | Right to receive products free from defects |
| Right to accurate information | Prohibition of false or misleading advertising |
| Right to fair contract terms | Prohibition of unfair contract clauses |
Product Liability Act — No Need to Prove Fault
The Product Liability Act B.E. 2551 (2008) is Thailand’s product liability law. Its key feature is strict liability: consumers do not need to prove that the manufacturer was negligent.
You only need to prove two things:
- The product was used or stored in a normal manner
- Damage occurred
Liability falls on manufacturers, importers, and sellers. This law applies equally to foreigners. Being a foreign national does not diminish your legal rights.
Where to File a Complaint
| Office | Contact | Scope |
|---|---|---|
| OCPB | 1166 (Consumer Hotline) | General consumer protection |
| FDA | FDA official website | Food and drug safety |
Always keep your receipts. They serve as critical evidence for returns and complaints.
The Lemon Law (Proposed)
The OCPB has been promoting a bill (commonly called a “lemon law”) that would establish consumer rights to immediate repair, replacement, or refund for defective products. Public hearings were held in 2024, but as of April 2026 the bill has not yet been enacted. If passed, it would significantly strengthen consumer protections.
5. Bringing Medicine, Supplements, and Food from Japan
Prescription Medicine
| Item | Rule |
|---|---|
| General prescription drugs | Up to 30 days’ supply (Drug Act B.E. 2510, Section 13(4)) |
| Recommended documentation | English translation of the prescription |
| Packaging | Keep in the original container |
| Narcotics / psychotropic substances | Up to 90 days’ supply, but FDA permit (Form IC-2) must be obtained at least 15 days before travel |
Supplements
Small quantities for personal use are generally fine. However, bringing large quantities may be treated as “importation” and fall under FDA regulations.
Japanese Food (Snacks, Retort Pouches, etc.)
Small quantities for personal use are generally acceptable. However, meat products (sausages, bacon, beef jerky, etc.) cannot be brought in without a permit from the Department of Livestock Development (DLD). There is no personal-use exemption — even small amounts require a permit. Fresh produce is also subject to quarantine.
6. Summary — Three Key Points
| Point | Details |
|---|---|
| ① Check for the FDA mark (อย.) | When buying processed food, look for the อย. mark and a 13-digit number |
| ② Read expiry dates in the Buddhist calendar | Buddhist Era = Gregorian year + 543. “2569” means 2026. Dates are in day/month/year order |
| ③ Product liability law protects you | No need to prove fault. Keep receipts and contact OCPB if needed |
Thailand’s food safety system is well-structured in law, with mandatory FDA registration and strict product liability. Simply developing the habit of checking the FDA mark when shopping will give you significantly greater peace of mind.
