Policy Text Block [Abstract]
Basis Of Presentation	Basis of Presentation The consolidated condensed financial statements are unaudited and have been prepared by Tyson Foods, Inc. (“Tyson,” “the Company,” “we,” “us” or “our”). Certain information and accounting policies 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 of the United States Securities and Exchange Commission. Although we believe the disclosures contained herein are adequate to make the information presented not misleading, these consolidated condensed financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our annual report on Form 10-K for the fiscal year ended October 3, 2015. Preparation of consolidated condensed financial statements requires us to make estimates and assumptions that affect reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated condensed financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We believe the accompanying consolidated condensed financial statements contain all adjustments, which are of a normal recurring nature, necessary to state fairly our financial position as of July 2, 2016, and the results of operations for the three and nine months ended July 2, 2016, and June 27, 2015. Results of operations and cash flows for the periods presented are not necessarily indicative of results to be expected for the full year.
Consolidation	Consolidation The consolidated condensed financial statements include the accounts of all wholly-owned subsidiaries, as well as majority-owned subsidiaries over which we exercise control and, when applicable, entities for which we have a controlling financial interest or variable interest entities for which we are the primary beneficiary. All significant intercompany accounts and transactions have been eliminated in consolidation.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements In March 2016, the Financial Accounting Standards Board ("FASB") issued guidance which simplifies several aspects of the accounting for employee share-based payment transactions, including the accounting for income taxes, forfeitures, and statutory tax withholding requirements, as well as classification of related amounts within the statement of cash flows and impact on earnings per share. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2016, our fiscal 2018. Early adoption is permitted and the application of the guidance requires various transition methods depending on the specific amendment. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In February 2016, the FASB issued guidance which created new accounting and reporting guidelines for leasing arrangements. The guidance requires lessees to recognize a right-of-use asset and lease liability for all leases with terms of more than 12 months. Recognition, measurement and presentation of expenses and cash flows arising from a lease will depend on classification as a finance or operating lease. The guidance also requires qualitative and quantitative disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2018, our fiscal 2020. Early adoption is permitted and the modified retrospective method should be applied. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In January 2016, the FASB issued guidance that requires most equity investments be measured at fair value, with subsequent changes in fair value recognized in net income. The guidance also impacts financial liabilities under the fair value option and the presentation and disclosure requirements on the classification and measurement of financial instruments. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2017, our fiscal 2019. It should be applied by means of a cumulative-effect adjustment to the balance sheet as of the beginning of the fiscal year of adoption, unless, equity securities do not have readily determinable fair values, in which case, the amendments should be applied prospectively. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In November 2015, the FASB issued guidance to simplify the presentation of deferred income taxes. The guidance requires that deferred tax liabilities and assets be classified as non-current in the balance sheet. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2016, our fiscal 2018, and may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. Early adoption is permitted. This new guidance is not expected to have a material impact on our consolidated financial statements. In July 2015, the FASB issued guidance which requires management to evaluate inventory at the lower of cost and net realizable value. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2016, our fiscal 2018. Early adoption is permitted and the prospective transition method should be applied. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In May 2015, the FASB issued guidance which removes the requirement to categorize all investments within the fair value hierarchy for which fair values are measured using the net asset value per share practical expedient. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2015, our fiscal 2017. Early adoption is permitted and the retrospective transition method should be applied. This new guidance is not expected to have a material impact on our consolidated financial statements. In April 2015, the FASB issued guidance on the recognition of fees paid by a customer for cloud computing arrangements. The guidance clarifies that if a cloud computing arrangement includes a software license, the customer should account for the software license consistent with the acquisition of other software licenses. If the arrangement does not include a software license, the customer should account for the arrangement as a service contract. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2015, our fiscal 2017, and should be applied prospectively or retrospectively. We are currently evaluating the impact this guidance will have on our consolidated financial statements. In April 2015, the FASB issued guidance which requires debt issuance costs to be presented in the balance sheet as a direct deduction from the associated debt liability; however, debt issuance costs related to revolving credit facilities will remain in other assets. The guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2015, our fiscal 2017. Early adoption is permitted and the retrospective transition method should be applied. This new guidance is not expected to have a material impact on our consolidated financial statements. In February 2015, the FASB issued guidance changing the analysis procedures that a reporting entity must perform to determine whether it should consolidate certain types of legal entities. All legal entities are subject to reevaluation under the revised consolidation model. The new guidance affects the following areas: (1) limited partnerships and similar legal entities, (2) evaluating fees paid to a decision maker or a service provider as a variable interest, (3) the effect of fee arrangements on the primary beneficiary determination, (4) the effect of related parties on the primary beneficiary determination, and (5) certain investment funds. This guidance is effective for annual reporting periods and interim periods within those annual reporting periods, beginning after December 15, 2015, our fiscal 2017. Early adoption is permitted and the retrospective or modified retrospective transition method should be applied. This new guidance is not expected to have a material impact on our consolidated financial statements. In May 2014, the FASB issued guidance changing the criteria for recognizing revenue. The guidance provides for a single five-step model to be applied to all revenue contracts with customers. The standard also requires additional financial statement disclosures that will enable users to understand the nature, amount, timing and uncertainty of revenue and cash flows relating to customer contracts. Companies have an option to use either a retrospective approach or cumulative effect adjustment approach to implement the standard. This guidance is effective for annual reporting periods and interim periods within those annual reporting periods beginning after December 15, 2017, our fiscal 2019. Early adoption is permitted for fiscal years beginning after December 15, 2016, our fiscal 2018. We are currently evaluating the impact this guidance will have on our consolidated financial statements.
