Organization, Consolidation and Presentation of Financial Statements [Abstract]
Consolidated Financial Statements	Consolidated Financial Statements The Company operates on the basis of a 52/53-week fiscal year ending on the Sunday falling on or before December 31. The reader should assume any reference we make to a particular year (for example, 2014) in the notes to these Consolidated Financial Statements applies to our fiscal year and not the calendar year. The consolidated financial statements include the accounts of Pilgrim’s Pride Corporation and its majority owned subsidiaries. We eliminate all significant affiliate accounts and transactions upon consolidation.
Foreign Currency Transactions and Translations	The Company measures the financial statements of its Mexico subsidiaries as if the U.S. dollar were the functional currency. Accordingly, we remeasure assets and liabilities, other than non-monetary assets, of the Mexico subsidiaries at current exchange rates. We remeasure nonmonetary assets using the historical exchange rate in effect on the date of each asset's acquisition. We remeasure income and expenses at average exchange rates in effect during the period, except for certain accounts which are remeasured at a historical rate. Currency exchange gains or losses are included in the line item Foreign currency transaction losses (gains) in the Consolidated Statements of Operations.
Revenue Recognition	Revenue Recognition We recognize revenue when all of the following circumstances are satisfied: (i) persuasive evidence of an arrangement exits, (ii) price is fixed or determinable, (iii) collectability is reasonably assured and (iv) delivery has occurred. Delivery occurs in the period in which the customer takes title and assumes the risks and rewards of ownership of the products specified in the customer's purchase order or sales agreement. Revenue is recorded net of estimated incentive offerings including special pricing agreements, promotions and other volume-based incentives. Revisions to these estimates are charged back to net sales in the period in which the facts that give rise to the revision become known. Taxes collected from customers and remitted to governmental authorities are excluded from revenues.
Shipping and Handling Costs	Shipping and Handling Costs Costs associated with the products shipped to customers are recognized in cost of sales.
Advertising Costs	Advertising Costs The Company expenses advertising costs as incurred. Advertising costs are included in selling, general and administrative expenses
Research and Development Costs	Research and Development Costs Research and development costs are expensed as incurred.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers highly liquid investments with a maturity of three months or less when acquired to be cash equivalents. The majority of the Company's disbursement bank accounts are zero balance accounts where cash needs are funded as checks are presented for payment by the holder. Checks issued pending clearance that result in overdraft balances for accounting purposes are classified as accounts payable and the change in the related balance is reflected in operating activities on the Consolidated Statements of Cash Flows.
Investments in Securities	Investments in Securities The Company’s current investments are comprised of fixed income securities, primarily commercial paper. These investments are classified as available-for-sale. These securities are recorded at fair value, and unrealized holding gains and losses are recorded, net of tax, as a separate component of accumulated other comprehensive income. Investments in fixed income securities with remaining maturities of less than one year and those identified by management at the time of purchase for funding operations in less than one year are classified as current assets. Investments in fixed income securities with remaining maturities in excess of one year that management has not identified at the time of purchase for funding operations in less than one year are classified as long-term assets. Unrealized losses are charged against net earnings when a decline in fair value is determined to be other than temporary. Management reviews several factors to determine whether a loss is other than temporary, such as the length of time a security is in an unrealized loss position, the extent to which fair value is less than amortized cost, the impact of changing interest rates in the short and long term, and the Company’s intent and ability to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. The Company determines the cost of each security sold and each amount reclassified out of accumulated other comprehensive income into earnings using the specific identification method. Purchases and sales are recorded on a trade date basis. Investments in entities in which the Company has an ownership interest greater than 50% and exercises control over the entity are consolidated in the Consolidated Financial Statements. Investments in entities in which the Company has an ownership interest between 20% and 50% and exercises significant influence are accounted for using the equity method. The Company invests from time to time in ventures in which its ownership interest is less than 20% and over which it does not exercise significant influence. Such investments are accounted for under the cost method. The fair values for investments not traded on a quoted exchange are estimated based upon the historical performance of the ventures, the ventures’ forecasted financial performance and management’s evaluation of the ventures’ viability and business models. To the extent the book value of an investment exceeds its assessed fair value, the Company will record an appropriate impairment charge. Thus, the carrying value of the Company’s investments approximates fair value.
Accounts Receivable	Accounts Receivable The Company records accounts receivable when revenue is recognized. We record an allowance for doubtful accounts, reducing our receivables balance to an amount we estimate is collectible from our customers. Estimates used in determining the allowance for doubtful accounts are based on historical collection experience, current trends, aging of accounts receivable, and periodic credit evaluations of our customers’ financial condition. We write off accounts receivable when it becomes apparent, based upon age or customer circumstances, that such amounts will not be collected. Generally, the Company does not require collateral for its accounts receivable.
Inventories	Inventories Live chicken inventories are stated at the lower of cost or market and breeder hens at the lower of cost, less accumulated amortization, or market. The costs associated with breeder hens are accumulated up to the production stage and amortized over their productive lives using the unit-of-production method. Finished poultry products, feed, eggs and other inventories are stated at the lower of cost (average) or market. We record valuation adjustments for our inventory and for estimated obsolescence at or equal to the difference between the cost of inventory and the estimated market value based upon known conditions affecting inventory, including significantly aged products, discontinued product lines, or damaged or obsolete products. We allocate meat costs between our various finished chicken products based on a by-product costing technique that reduces the cost of the whole bird by estimated yields and amounts to be recovered for certain by-product parts. This primarily includes leg quarters, wings, tenders and offal, which are carried in inventory at the estimated recovery amounts, with the remaining amount being reflected as our breast meat cost. Generally, the Company performs an evaluation of whether any lower of cost or market adjustments are required at the country level based on a number of factors, including: (i) pools of related inventory, (ii) product continuation or discontinuation, (iii) estimated market selling prices and (iv) expected distribution channels. If actual market conditions or other factors are less favorable than those projected by management, additional inventory adjustments may be required.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost, and repair and maintenance costs are expensed as incurred. Depreciation is computed using the straight-line method over the estimated useful lives of these assets. Estimated useful lives for building, machinery and equipment are five to 33 years and for automobiles and trucks are three to ten years. The charge to income resulting from amortization of assets recorded under capital leases is included with depreciation expense. The Company records impairment charges on long-lived assets held for use when events and circumstances indicate that the assets may be impaired and the undiscounted cash flows estimated to be generated by those assets are less than the carrying amount of those assets. When the above is true, the impairment charge is determined based upon the amount the net book value of the assets exceeds their fair market value. In making these determinations, the Company utilizes certain assumptions, including, but not limited to: (i) future cash flows estimated to be generated by these assets, which are based on additional assumptions such as asset utilization, remaining length of service and estimated salvage values, (ii) estimated fair market value of the assets and (iii) determinations with respect to the lowest level of cash flows relevant to the respective impairment test, generally groupings of related operational facilities. Given the interdependency of the Company’s individual facilities during the production process, which operate as a vertically integrated network, it evaluates impairment of assets held for use at the country level (i.e., the U.S. and Mexico). Management believes this is the lowest level of identifiable cash flows for its assets that are held for use in production activities. At the present time, the Company’s forecasts indicate that it can recover the carrying value of its assets held for use based on the projected undiscounted cash flows of the operations. The Company records impairment charges on long-lived assets held for sale when the carrying amount of those assets exceeds their fair value less appropriate selling costs. Fair value is based on amounts documented in sales contracts or letters of intent accepted by the Company, amounts included in counteroffers initiated by the Company, or, in the absence of current contract negotiations, amounts determined using a sales comparison approach for real property and amounts determined using a cost approach for personal property. Under the sales comparison approach, sales and asking prices of reasonably comparable properties are considered to develop a range of unit prices within which the current real estate market is operating. Under the cost approach, a current cost to replace the asset new is calculated and then the estimated replacement cost is reduced to reflect the applicable decline in value resulting from physical deterioration, functional obsolescence and economic obsolescence. Appropriate selling costs includes reasonable broker's commissions, costs to produce title documents, filing fees, legal expenses and the like. We estimate appropriate closing costs as 4% to 6% of asset fair value. This range of rates is considered reasonable for our assets held for sale based on historical experience.
Identified Intangible Assets	Identified Intangible Assets Our identified intangible assets consist of assets subject to amortization such as trade names, customer relationships and non-compete agreements. We calculate amortization of those assets that are subject to amortization on a straight-line basis over the estimated useful lives of the related assets. The useful lives range from three to 15 years for trade names and non-compete agreements and 13 years for customer relationships. We review intangible assets subject to amortization for impairment whenever an event or change in circumstances indicates the carrying values of the assets may not be recoverable. We test intangible assets subject to amortization for impairment and estimate their fair values using the same assumptions and techniques we employ on property, plant and equipment.
Book Overdraft Balances	Book Overdraft Balances The majority of the Company's disbursement bank accounts are zero balance accounts where cash needs are funded as checks are presented for payment by the holder. Checks issued pending clearance that result in overdraft balances for accounting purposes are classified as accounts payable and the change in the related balance is reflected in operating activities on the Consolidated Statements of Cash Flows.
Litigation and Contingent Liabilities	Litigation and Contingent Liabilities The Company is subject to lawsuits, investigations and other claims related to employment, environmental, product and other matters. The Company is required to assess the likelihood of any adverse judgments or outcomes, as well as potential ranges of probable losses, to these matters. The Company estimates the amount of reserves required for these contingencies when losses are determined to be probable and after considerable analysis of each individual issue. The Company expenses legal costs related to such loss contingencies as they are incurred. The accrual for environmental remediation liabilities is measured on an undiscounted basis. These reserves may change in the future due to changes in the Company’s assumptions, the effectiveness of strategies, or other factors beyond the Company’s control.
Accrued Self Insurance	Accrued Self Insurance Insurance expense for casualty claims and employee-related health care benefits are estimated using historical and current experience and actuarial estimates. Stop-loss coverage is maintained with third-party insurers to limit the Company’s total exposure. Certain categories of claim liabilities are actuarially determined. The assumptions used to arrive at periodic expenses are reviewed regularly by management. However, actual expenses could differ from these estimates and could result in adjustments to be recognized.
Income Taxes	Income Taxes The Company follows provisions under ASC 740-10-30-27 in the Expenses-Income Taxes topic with regard to members of a group that file a consolidated tax return but issue separate financial statements. The Company files its own U.S. federal tax return, but it is included in certain state consolidated returns with JBS USA. The income tax expense of the Company is computed using the separate return method. The provision for income taxes has been determined using the asset and liability approach of accounting for income taxes. Under this approach, deferred income taxes reflect the net tax effect of temporary differences between the book and tax bases of recorded assets and liabilities, net operating losses and tax credit carry forwards. The amount of deferred tax on these temporary differences is determined using the tax rates expected to apply to the period when the asset is realized or the liability is settled, as applicable, based on the tax rates and laws in the respective tax jurisdiction enacted as of the balance sheet date. The Company reviews its deferred tax assets for recoverability and establishes a valuation allowance based on historical taxable income, potential for carry back of tax losses, projected future taxable income, applicable tax strategies, and the expected timing of the reversals of existing temporary differences. A valuation allowance is provided when it is more likely than not that some or all of the deferred tax assets will not be realized. Valuation allowances have been established primarily for net operating loss carry forwards of certain foreign subsidiaries. See “Note 11. Income Taxes” to the Consolidated Financial Statements. The Company deems its earnings from Mexico as of December 28, 2014 to be permanently reinvested. As such, U.S. deferred income taxes have not been provided on these earnings. If such earnings were not considered indefinitely reinvested, certain deferred foreign and U.S. income taxes would be provided. For activity after 2008, the Company did not permanently reinvest its earnings in Puerto Rico. Therefore, net earnings generated in Puerto Rico have U.S. taxes provided as if the earnings were distributed. The Company follows provisions under ASC 740-10-25 that provide a recognition threshold and measurement criteria for the financial statement recognition of a tax benefit taken or expected to be taken in a tax return. Tax benefits are recognized only when it is more likely than not, based on the technical merits, that the benefits will be sustained on examination. Tax benefits that meet the more-likely-than-not recognition threshold are measured using a probability weighting of the largest amount of tax benefit that has greater than 50% likelihood of being realized upon settlement. Whether the more-likely-than-not recognition threshold is met for a particular tax benefit is a matter of judgment based on the individual facts and circumstances evaluated in light of all available evidence as of the balance sheet date. See “Note 11. Income Taxes” to the Consolidated Financial Statements.
Pension and Other Postemployment Benefits	Pension and Other Postemployment Benefits Our pension and other postemployment benefit costs and obligations are dependent on the various actuarial assumptions used in calculating such amounts. These assumptions relate to discount rates, long-term return on plan assets and other factors. We base the discount rate assumptions on current investment yields on high-quality corporate long-term bonds. We determine the long-term return on plan assets based on historical portfolio results and management’s expectation of the future economic environment. Actual results that differ from our assumptions are accumulated and, if in excess of the lesser of 10% of the projected benefit obligation or the fair market value of plan assets, amortized over either (i) the estimated average future service period of active plan participants if the plan is active or (ii) the estimated average future life expectancy of all plan participants if the plan is frozen.
Operating Leases	Operating Leases Rent expense for operating leases is recorded on a straight-line basis over the lease term unless the lease contains an escalation clause which is not fixed or determinable. The lease term begins when we have the right to control the use of the leased property, which is typically before rent payments are due under the terms of the lease. If a lease has a fixed or determinable escalation clause, the difference between rent expense and rent paid is recorded as deferred rent and is included in the Consolidated Balance Sheets. Rent for operating leases that do not have an escalation clause or where escalation is based on an inflation index is expensed over the lease term as it is payable.
Risk Management	Risk Management The Company attempts to mitigate commodity purchase exposures through a program of risk management that includes the use of forward purchase contractual obligations and derivative financial instruments. The Company will also occasionally purchase derivative financial instruments in an attempt to mitigate currency exchange rate exposure related to the net assets of its Mexico operations that are denominated in Mexican pesos. The Company's Mexico subsidiaries also attempt to mitigate the foreign currency exposure on certain U.S. dollar-denominated transactions through the use of derivative financial instruments. We recognize all derivative financial instruments in the Consolidated Balance Sheets at fair value. We elected not to designate derivative financial instruments executed to mitigate commodity purchase exposures and foreign currency exposures as hedges of forecasted transactions. Therefore, we recognize changes in the fair value of these derivative financial instruments immediately in earnings. Gains or losses related to both the commodity derivative financial instruments and the foreign currency derivative financial instruments are included in the line item Cost of sales in the Consolidated Statements of Operations.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. (“U.S. GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. We make significant estimates in regard to receivables collectability; inventory valuation; realization of deferred tax assets; valuation of long-lived assets; valuation of contingent liabilities, liabilities subject to compromise and self insurance liabilities; valuation of pension and other postretirement benefits obligations; and valuation of acquired businesses.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance on revenue recognition, which provides for a single five-step model to be applied to all revenue contracts with customers. The new 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. There is no option for early adoption. The provisions of the new guidance will be effective as of the beginning of our 2017 fiscal year. We are currently evaluating the impact of the new guidance on our financial statements and have not yet selected a transition approach to implement the standard.

We make significant estimates in regard to receivables collectability; inventory valuation; realization of deferred tax assets; valuation of long-lived assets; valuation of contingent liabilities, liabilities subject to compromise and self insurance liabilities; valuation of pension and other postretirement benefits obligations; and valuation of acquired businesses.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued new accounting guidance on revenue recognition, which provides for a single five-step model to be applied to all revenue contracts with customers. The new 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. There is no option for early adoption. The provisions of the new guidance will be effective as of the beginning of our 2017 fiscal year. We are currently evaluating the impact of the new guidance on our financial statements and have not yet selected a transition approach to implement the standard.
