Item 1.	Security and Issuer Shares of Common Stock, $0.01 par value Food Technology Service, Inc. 502 Prairie Mine Road Mulberry, Florida 33860 USA ________________________________________________________________________________________________
Item 2.	Identity and Background N/A ________________________________________________________________________________________
Item 3.	Source and Amount of Funds or Other Consideration. N/A ________________________________________________________________________________________
Item 4.	Purpose of Transaction Item 4 is hereby amended. As confirmed by letter Agreement dated May 18, 2000 (previously filed) Food Technology Service, Inc.'s ("FTSI") indebtedness to MDS Nordion ("Nordion") as at February 4, 2000 is in the amount of $963,194 (the "Debt"). Additionally, such Letter Agreement provides that the right of conversion of interest on the Debt accruing from February 5, 2000 to January 1, 2001, into shares of FTSI, has been waived by Nordion. By Letter Agreements dated November 20, 2000 and November 26, 2001, Nordion has extended its waiver of the right of conversion of interest accruing on the Debt from January 1, 2001 to January 1, 2003. On December 17, 2002, MDS Nordion exercised its option to convert $300,000US of the Debt into common shares of FTSI, (leaving a remaining balance of convertible debt of $663,194US, ("Outstanding Indebtedness")). The amount of $300,000US is convertible into shares of FTSI at the conversion rate of 70% of the closing price, on the last trade date, prior to the date of exercise of the conversion right. By notice dated December 17, 2002 Nordion has extended its waiver of the right of conversion of interest accruing on Outstanding Indebtedness accruing from January 1, 2003 to January 1, 2004. Since the 13D Amendment 27, filed with the SEC in December 2002, (which calculated the amount of beneficially owned shares based on the closing share price on December 17^th, 2002 i.e., 70% of $0.85 or $0.595) the closing share price of FTSI on January 15, 2003 increased to $1.14. Seventy percent (70%) thereof corresponds to a conversion price of $ 0.798. At the close of business on January 15, 2003 Nordion beneficially owned 4,947,652 shares of stock, which constitutes approximately 43.7% of the outstanding shares of FTSI. The number of shares beneficially owned as of January 15, 2003 has been computed by aggregating (i) the number of shares that Nordion actually owns (including 504,201 shares issued upon exercise of conversion of the $300,000US of the Debt on December 17, 2002 and the private sale of 75,000 shares on January 15, 2003); and (ii) the number of shares into which Nordion could elect to convert the Outstanding Indebtedness on the basis of the closing price of January 15, 2003 (i.e., 70% of $1.14 or $0.798) or 831,070 shares. Pursuant to publicly available information 10,496,837 shares of Food Technology Service, Inc. were issued and outstanding on January 15, 2003. ________________________________________________________________________________________
Item 5.	Interest in Securities of the Issuer See Item 4 ________________________________________________________________________________________
Item 6.	Contracts, Arrangements, Understanding or Relationships with Respect to Securities of the Issuer. By notice dated December 17, 2002, MDS Nordion exercised its option to convert $300,000US of FTSI indebtedness into common shares of FTSI based on 70% of the closing price of FTSI shares listed on NASDAQ on the last trade date prior to the date of exercise of the conversion right, and MDS Nordion extended its waiver of the right of conversion of interest accruing on FTSI Outstanding Indebtedness, to January 1, 2004. ________________________________________________________________________________________
