Summary of Significant Accounting Policies (Policies)	Jul. 03, 2011
Accounting Policies [Abstract]
Description of Business	Description of Business Ruddick Corporation (the "Company") is a holding company which, through its wholly-owned subsidiaries, is engaged in two primary businesses: Harris Teeter, Inc. ("Harris Teeter") operates a regional chain of supermarkets in eight states primarily in the southeastern and mid-Atlantic United States, and the District of Columbia; and American & Efird, Inc. ("A&E") manufactures and distributes industrial sewing thread, embroidery thread and technical textiles on a global basis.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated condensed financial statements include the accounts of Ruddick Corporation and subsidiaries, including its wholly-owned operating companies, Harris Teeter and A&E, collectively referred to herein as the Company. All material intercompany amounts have been eliminated. In the opinion of management, the information furnished reflects all adjustments (consisting only of normal recurring accruals) necessary to present fairly the results for the interim periods presented. The statements have been prepared by the Company pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States have been condensed or omitted pursuant to such rules and regulations. It is suggested that these consolidated condensed financial statements be read in conjunction with the consolidated financial statements and accompanying notes included in the Company's 2010 Annual Report on Form 10-K filed with the SEC on December 1, 2010 ("Company's 2010 Annual Report"). The Company's Consolidated Condensed Balance Sheet as of October 3, 2010 has been derived from the audited Consolidated Balance Sheet as of that date. The results of operations for the 13 and 39 weeks ended July 3, 2011 are not necessarily indicative of results for a full year.
Reporting Periods	Reporting Periods The Company's quarterly reporting periods are generally 13 weeks and periodically consist of 14 weeks because the Company's fiscal year ends on the Sunday nearest to September 30. However, Harris Teeter's fiscal periods end on the Tuesday following the Company's fiscal period end.
Derivatives	Derivatives The Company utilizes derivative financial instruments to hedge its exposure to changes in interest rates. All derivative financial instruments are recorded on the balance sheet at their respective fair value. The Company does not use financial instruments or derivatives for any trading or other speculative purposes. Harris Teeter enters into purchase commitments for a portion of the fuel utilized in its distribution operations. Harris Teeter expects to take delivery of and to utilize these resources in a reasonable period of time and in the conduct of normal business. Accordingly, these fuel purchase commitments qualify as normal purchases. Harris Teeter also utilizes derivative financial instruments to hedge its exposure in the price variations of fuel.
Statements of Consolidated Cash Flows	Statements of Consolidated Cash Flows A portion of the sales and operating costs of A&E's foreign operations are denominated in currencies other than the U.S. dollar. This creates an exposure to foreign currency exchange rates. The impact of changes in the relationship of other currencies to the U.S. dollar has historically not been significant, and such changes in the future are not expected to have a material impact on the Company's results of operations or cash flows.
New Accounting Standards	New Accounting Standards In June 2009, the Financial Accounting Standards Board issued a new standard that: changed the definition of a variable interest entity ("VIE"); contained new criteria for determining the primary beneficiary of a VIE; required enhanced disclosures to provide more information about a company's involvement in a VIE; and, increased the frequency of required reassessments to determine whether a company is the primary beneficiary of a VIE. The adoption of this standard at the beginning of the fiscal 2011 had no impact on the Company's financial position, results of operations or cash flows.
Reclassifications	Reclassifications To conform with classifications used in the current year, the financial statements for the prior year reflect certain reclassifications.

Disclosure of accounting policy for its derivative instruments and hedging activities. Disclosure may include: (1) Each method used to account for derivative financial instruments and derivative commodity instruments ("derivatives"); (2) the types of derivatives accounted for under each method; (3) the criteria required to be met for each accounting method used, including a discussion of the criteria required to be met for hedge or deferral accounting and accrual or settlement accounting (for example, whether and how risk reduction, correlation, designation, and effectiveness tests are applied); (4) the accounting method used if the criteria specified for hedge accounting are not met; (5) the method used to account for termination of derivatives designated as hedges or derivatives used to affect directly or indirectly the terms, fair values, or cash flows of a designated item; (6) the method used to account for derivatives when the designated item matures, is sold, is extinguished, or is terminated. In addition, the method used to account for derivatives designated to an anticipated transaction, when the anticipated transaction is no longer likely to occur; and (7) where and when derivatives, and their related gains or losses are reported in the statement of financial position, cash flows, and results of operations and (8) an accounting policy decision to offset fair value amounts with counterparties. An entity may also describe its embedded derivatives, and the method(s) used to determine the fair values of derivatives and any significant assumptions used in such valuations.
