Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies [Text Block]	COMMITMENTS AND CONTINGENCIES In addition to the discussions below, we have pending certain other legal actions and claims incurred in the normal course of business. We record accruals for such contingencies when it is probable that a liability will be incurred and the amount of the loss can be reasonably estimated. As of September 26, 2015, we have determined that the liabilities associated with certain litigation matters are probable and can be reasonably estimated. We have accrued for these matters and will continue to monitor each related legal issue and adjust accruals for new information and further development. Other than what is disclosed below, we consider the litigation matters to be immaterial individually and in the aggregate. Texas Medicaid In June 2013, we received notices from the Office of the Attorney General for the State of Texas, of civil investigative demands to two of our affiliates, Perrigo Pharmaceuticals Company and Paddock Laboratories, LLC, for information under the Texas Medicaid Fraud Prevention Act relating to the submission of prices to Texas Medicaid in claims for reimbursement for drugs. We have cooperated with requests for information and are in the process of evaluating this and other information. While we do not know the full extent of our potential liability at this time and intend to vigorously defend against any claims, we could be subject to material penalties and damages. We initially established a contingency loss accrual of $15.0 million to cover potential settlement or other outcomes. Due to changes in circumstances, during the three months ended March 28, 2015, we accrued an additional $9.0 million. In addition, we recorded a receivable of $7.0 million representing the amount we expect to collect from the previous owners of Paddock Laboratories, LLC. We cannot predict whether we will obtain a settlement on terms we deem acceptable, or whether a settlement or potential liability for these claims will be materially higher than the amount recorded. Eltroxin During October and November 2011, nine applications to certify a class action lawsuit were filed in various courts in Israel related to Eltroxin, a prescription thyroid medication manufactured by a third party and distributed in Israel by Perrigo Israel Agencies Ltd. The respondents include Perrigo Israel Pharmaceuticals Ltd. and/or Perrigo Israel Agencies Ltd., the manufacturers of the product, and various healthcare providers who provide healthcare services as part of the compulsory healthcare system in Israel. One of the applications was dismissed and the remaining eight applications were consolidated into one application. The applications arose from the 2011 launch of a reformulated version of Eltroxin in Israel. The consolidated application generally alleges that the respondents (a) failed to timely inform patients, pharmacists and physicians about the change in the formulation; and (b) failed to inform physicians about the need to monitor patients taking the new formulation in order to confirm patients were receiving the appropriate dose of the drug. As a result, claimants allege they incurred the following damages: (a) purchases of product that otherwise would not have been made by patients had they been aware of the reformulation; (b) adverse events to some patients resulting from an imbalance of thyroid functions that could have been avoided; and (c) harm resulting from the patients' lack of informed consent prior to the use of the reformulation. Several hearings on whether or not to certify the consolidated application took place in December 2013 and January 2014. On May 17, 2015, the District Court certified the motion against Perrigo Israel Agencies Ltd. and dismissed it against the remaining respondents, including Perrigo Israel Pharmaceuticals Ltd. On June 16, 2015, Perrigo submitted a motion for permission to appeal the decision to certify to the Israeli Supreme Court together with a motion to stay the proceedings of the class action until the motion for permission to appeal is adjudicated. Other than requiring Perrigo to file its statement of defense to the underlying proceedings, the underlying proceedings have been stayed pending a decision on the motion to appeal. At this stage, we cannot reasonably predict the outcome or the liability, if any, associated with these claims. Tysabri^® Product Liability Lawsuits Perrigo Company plc and collaborator Biogen Idec are co-defendants in product liability lawsuits arising out of the occurrence of Progressive Multifocal Leukoencephalopathy, a serious brain infection, and serious adverse events, including deaths, which occurred in patients taking Tysabri^®. Perrigo Company plc and Biogen Idec will each be responsible for 50% of losses and expenses arising out of any Tysabri^® product liability claims. While these lawsuits will be vigorously defended, management cannot predict how these cases will be resolved. Adverse results in one or more of these lawsuits could result in substantial judgments against us.
