AFP  ps: AFP (France), Mar. 6, 2012:  For "unable to document any legitimate food safety risk and used non-scientific reasons to justify their bans", Taiwan plans to lift ban on most drug-treated US beef, but internal organs from cattle containing ractopamine and ractopamine-treated pork products will still be banned.   In 2006 Taipei relaxed the rules to permit imports of boneless beef.   Till nowadays US meat with ractopamine, is still banned in China and the European Union.


   Costco sold out almost all beef products containing banned drugs  Jan. 15, 2011 19:15pm, by <CTS>, Taiwan 

Taiwanese government found Costco and RT-mart sold beef/steaks containing residue of banned chemical stuff ― Paylean, lean-meat-enhancing drugs (belong to B-agonist, i.e.,  Ractopamine, Clenbuterol, etc ).

Taiwanese health authorities ordered Costco and RT-mart to remove all remaining beef products (that tested positive for Paylean) from shelves,  but Costco ( 6 stores/branches ) had already sold out almost all of those beef/steaks . 

Why can those beef be imported to Taiwan ?   Taiwan's government confessed they didn't check every box.

How can people tell which is dangerous beef/steak?  The answer is you can't tell just by their look.


Costco's banned-drug beef news by media

<Taipei Times> Taiwan, Jan 16, 2011

    3  beef products were found leanness drugs ...RT-mart with a reading of 0.64 ppb, ... COSTCO ... 1.46 ppb and 2.84 ppb. (Costco is about 3 times the test-value of RT-mart)

<China Times> Taiwan, Jan 16, 2011

    3  out of 11 randomly selected sampling in regular check were found lean-meat-enhancing drugs, Such a high ratio (nearly 30%) scares Taiwanese ―  "where's eating safety in Taiwan?" ...... Taiwanese Department of Health didn't order to remove remaining beef products with banned drugs as soon as they informed the public of the issue, and DOH has no idea about the source even till next day noon ...

<Liberty Times> Taiwan, Jan 16, 2011

   ◎ Headline of Life News : Banned drugs in beef probably had already been eaten by consumers/customers.

    ◎ Taiwan's Department of Health declared again and again .... but if DOH had not made such  simple chemical tests, none to mention to make comparatively complicated tests (e.g., 普立昂變性蛋白) ....

<United Daily News> Taiwan, Jan 16, 2011

   ◎ Europe ( same as Taiwan ) bans beef products containing lean-meat-enhancing drugs.

<ETTV> (channel 57,  9:00 ~ ) Taiwan, Jan 20, 2011

     160+ countries banned Paylean,  US allows minor Paylean, but American only eat meat, Taiwanese eat every part of them (liver, heart, etc organs...), the rest part contains banned drugs more than 20 times than meat itself... (ps: That's the difference !)

(banned drugs in beef may result in Palpitation etc, and even serious heart diseases)

About Costco :

   The Costco Wholesale Corp. outlet in Taipei's Neihu high-tech district, (Taiwan's only wholesale club chain) is the 567-store chain's second most profitable, behind a Korean outlet.  ( 2 other Taiwanese Costco stores are also ranking top 10, totally 5 Taiwanese stores stand top 20)  Costco is considering to enter an even bigger market : China.

   However, This US Corp. in  Taiwan (Nei Hu) is not very democratic and modern (seems to me)  -   since 1995 there's no  "questions & comments" email-box provided for customers,  unlike COSTCO USA  "Back to basics".    Costco Taiwan said (via the phone, 2010 ) that customers can drive ( long way for me) to drop a  letter to their suggestion-box in NeiHu, this reminds me an old western cartoon of  satire & humor :  suggestion box is hanged in a high place .

  Costco's Taiwan chief, Mr. Richard Chang, said that one reason they are profitable during these bad economic days and one way of distinguishing itself is to use Costco's U.S. policy of trying to guarantee its prices are the market's lowest (Costco has worked with local vendors to cut costs and prices), but it's not difficult to find lower price goods in some other supermarkets in Taiwan, like RT-mart and French Carrefour.

   Below please find some examples  :

  (1) VitaMix blender in Costco Taiwan is asking about USD 800, compare model 5200 blender in USA for only USD449.   or

       Besides, Costco's Vitamix is made for Taiwanese or Asian only, not same as Vitamix 5200 in Costco USA. 

  (2)  As for steaks imported from USA, Costco's tag price is not the lowest.

RT-Mart offers NT 29.9(about USD0.95) per 100g, for steak imported from USA,
a lot cheaper than Costco's price.


  (3) Costco's Centrum is made for Taiwanese (or Asian?) too, not those sold in USA or some international airports.  (I cannot find many items for elders in Nei-hu, like <supports alertness & short-term memory>)

  (4) Ralph Lauren POLO clothes and pants is more expensive than some widely-known "outlet" garment shops in Taipei, Macau (Trav. Praia Grande; Avenida de D. Joao IV), China (Shanghai Taobao City, XiangYang Market, but I heard 90+% of them are fake ones, and many other places like GuangZou, Zhuhai ), etc.

        Ralph Lauren official outlet online, Macy's (USA) clearance sale and some others provide with good-price, more assorted products,
        i.e.,   Macys is offering Ralph Lauren Andrew Stretch Lorduroy for big & tall, original price USD 125 down to USD24.99,
                 Shirt - Batik Striped Henley USD 98 down to USD 41.99.     May 15, 2010
        i.e.,   Ralph Lauren POLO outlet online offers 35 categories : Suits, Ties, belts, outwear, coats, leather goods, accessories, hats, etc. Costco Taiwan has
                 comparatively a lot smaller items to sell.

RL POLO outlet online

Macy's online

   (5)  Costco has not many watches (few kinds for each brand), I saw (early May 2010) a TISSOT - PRC200 leather ( watch for men ) for about USD 320 (NT9799), but Amazon offers cheaper price for about USD 259.99

          Omega is bringing a suit case against Costco for selling their products, but I don't see any Omega watches in Costco Neihu here.

   (6)  CostCo Taiwan doesn't have online products , but Costco USA and Canada do.  see below :


   (7)   <Fast Company> described Costco as an enterprise thinking highly of customers (higher than Costco stock-holders), but, Costco Taiwan Neihu doesn't have any email-box for customer's suggestion and communication since 1995,  in contrast,  Carrefour Taiwan, RT-Mart Taiwan, and Costco USA all do have.


   (8)   I only saw small number of top brand sport-shoes (for running, basketball, etc, May 2010 ) in aisles of merchandise stacked floor-to-ceiling.
          Costco sells less than 4000 kinds of products, others ( major rivals are RT-Mart of Taiwan and China, French Carrefour ) are between 40000
            and 80000 .

   (9)   Costco declares giving U.S. merchandise a local twist, but NeiHu store only has some sushi, I don't see (middle May '10) any fresh Japanese
          sashimi (raw fish slices), which is most favorite food in all 5 star hotels (all-you-can-eat-buffet) in Taiwan.

   (10)   Quite many items Costco sells are large-packed, if you don't have a large refrigerator, probably better choose RT-mart or Carrefour nearby. 


Costco Taiwan focuses on high-income, high-education market segmentation.

Costco said Taiwanese love imported products, unlike Japanese and Korean have strong brands of their own.  So, about two-fifths of the chain's merchandise is imported from USA.   Costco wants to make it as authentic as possible,  also localize.

Some customers feel Costco treats them as thieves for Costco's double checking customers receipts, Costco said their barcode scanner sometimes may make mistakes, that's why .... 

( reported in 2010, for precise translation pls. refer to Chinese version web-pages  )

ps:  (1) Omega watches available now in Costco, but price is not about half price as news reported several years ago.

      (2) Now Costco has member-comment form on the net for customers to send opinions, as for privacy policy ... I don't quite understand....     6.8.2014
