Update on PEDV Impact in Japan

According to the Ministry of Agriculture, Forestry and Fisheries (MAFF), this is the latest update (numbers as of May 26) on the porcine epidemic diarrhea virus (PEDV) situation in Japan.

Since PEDV was first detected* in Okinawa prefecture in October of last year:

• 701 production facilities in 38 prefectures have detected the disease
• 743,138 pigs have been diagnosed as positive
• 199,935 pigs have died since the October outbreak, equivalent to about 1.2 percent of Japan’s annual hog slaughter

In addition to mandatory reporting requirements, other measures taken in Japan to prevent spread of PEDV include disinfection of trucks and handling facilities. MAFF also reports that sow vaccinations have been effective in reducing piglet mortality rates.

Japan’s pork carcass prices surged in April – in yen terms, up 25 percent year-over-year and up 17 percent from March. In U.S. dollars, April prices averaged $2.59 per pound, up 19 percent from a year ago. The PEDV impact on Japan’s production, high prices for imported pork and tight frozen inventories (March inventories were down 7 percent year-over-year) have contributed to the run-up in domestic hog prices.

April import data showed Japan’s chilled/frozen pork imports were 72,794 metric tons (mt), up 17 percent from a year ago. This included a 9 percent increase from the United States (25,799 mt) and larger imports from Denmark, Mexico and Spain.

*PEDV was originally detected in Japan in 1997 at three production facilities, resulting in the death of 185 piglets. Small-scale outbreaks were also reported in 1998, 1999 and 2001.
