TRANSFER ORDER
SARAH S. VANCE, Chair.Before the Panel:* Before the Panel are four dockets arising from a New York state investigation into the herbal supplements industry, which allegedly found based on DNA barcode testing that store brand supplements sold by Walgreens, Wal-Mart, GNC, and Target contained fillers and contaminants in place of the herbal ingredients listed on the product labels.
Plaintiffs in six actions move under 28 U.S.C. § 1407 to centralize each of the above-captioned dockets on a retailer-specific basis in various districts. In MDL No. 2619, plaintiff in one action seeks centralization of the Walgreens actions in the Northern District of Illinois. In MDL No. 2620, plaintiffs in three actions seek centralization of the Wal-Mart actions in the Western District of Arkansas or the Northern District of California. In MDL No. 2621, plaintiff in one action seeks centralization of the GNC actions in the Southern District of Florida or the Northern District of Illinois. In MDL No. 2622, plaintiff in one action seeks centralization of the Target actions in the Northern District of California or, alternatively, the Northern District of Illinois. This litigation currently consists of 35 actions, as listed on the attached schedules. The Panel has been notified of over 30 potentially related actions.1
All defendants2 and responding plaintiffs support centralization, but disagree on the structure of the proposed dockets (four retailer-specific MDLs or a single omnibus MDL) and the proposed transferee districts. Defendants Walgreens, Wal-Mart, Target, and NBTY support centralization of four retailer-specific MDLs before one judge in the Northern District of Illinois or, alternatively, in another district in which a defendant has its headquarters. Defendant GNC agrees, but proposes the Western District of Pennsylvania in the first instance and, alternatively, the Northern District of Illinois. Plaintiffs in 15 actions support the creation of four retailer-specific MDLs in separate districts. Plaintiffs in 28 actions support centralization of all actions before the Panel in a single district and, of those, plaintiffs in about a dozen actions argue for creation of a single omnibus MDL. In total, responding plaintiffs propose 12 districts for the various proposed MDLs: the Eastern and Western Districts of Arkansas; the Central, Northern, and Southern Districts of California; the Southern District of Florida; the Northern District of Illinois; the Western District of Kentucky; the District *1375of Minnesota; the Western District of Missouri; the Eastern District of New York; and the Southern District of Ohio.
We find that common factual questions in all actions unquestionably arise from’ the New York attorney general’s determination based on DNA barcode testing that certain herbal supplements sold by Walgreens, Wal-Mart, GNC, and Target do not contain the herbs advertised on the label and instead contain fillers or contaminants. Thus, discovery and motions concerning the testing will be substantially the same, regardless of the named defendant. At oral argument, no party disputed that all actions overlap on at least those matters.
The only issue is whether creation of a single multi-retailer MDL or four retailer-specific MDLs will achieve greater efficiencies. The parties supporting creation of retailer-specific MDLs argue that separate MDLs are warranted principally because (1) each defendant’s labeling, marketing, manufacturing, and sourcing practices will raise unique factual issues; (2) retailer-specific motions can be more efficiently presented and resolved in separate dockets;3 and (3) defendants are direct competitors and thus, will need to protect against the disclosure of confidential manufacturing, marketing, and other information.
In response, plaintiffs supporting a single multi-retailer MDL argue that (1) the central factual issues in all four dockets focus on the same New York attorney general investigation and, in particular, the DNA barcode testing; (2) since overlapping discovery and motions practice concerning the validity of the DNA testing will be substantial, centralization is necessary to avoid inconsistent rulings — a point defendants acknowledge; and (3) retailer-specific factual issues and protection of confidential proprietary information can be addressed by creating separate tracks for each retailer. These plaintiffs also argue that many actions allege NBTY is a common supplier for some or all involved retailers, which makes the creation of separate MDLs impracticable. They also note that there are at least seven actions asserting claims against all four retailers, which would be difficult to sever and transfer into four separate MDLs. These plaintiffs, along with defendants, assert that under any scenario, the proposed MDL(s) should be centralized before the same transferee judge because the proposed statewide and nationwide classes overlap substantially and present competing class definitions.
In our judgment, a single MDL encompassing all four retailers is necessary to ensure the just and efficient conduct of this litigation. In many situations, we are hesitant to bring together actions involving separate defendants and products, but where, as here, the actions stem from the same government investigation and there is significant overlap in the central factual issues, parties, and claims, we find that creation of a single MDL is warranted.4 A single MDL is the most appropriate vehicle for resolving defendants’ common challenges to the validity of the DNA testing, the anticipated common third-party *1376discovery involving the New York attorney general’s investigation, discovery of any common suppliers, and management of the competing putative classes. Although the advocates of separate MDLs have identified certain retailer-specific issues, Section 1407 does not require a complete identity of common factual issues or parties as a prerequisite to transfer, and the presence of additional facts is not significant where the actions arise from a common factual core.5 We are confident that the transferee judge can accommodate any issues involving the different products and defendants, including confidentiality and retailer-specific resolutions, in a manner that guarantees the just and efficient resolution of all cases.
Several parties have requested that we order the creation of separate tracks for each retailer, largely repeating the arguments of those advocating separate MDLs. But we have long left the degree of coordination of involved actions to the sound discretion of the transferee judge. See In re: Frito-Lay North America, Inc. “All Natural” Litig., 908 F.Supp.2d, 1379, 1380 (J.P.M.L.2012). We often have observed that the transferee court can employ any number of pretrial techniques, such as establishing separate discovery and motion tracks, to manage pretrial proceedings efficiently. In the Panel briefing, the parties have discussed additional case management tools that have been successful in other MDLs. It is incumbent upon the parties to bring their concerns to the attention of the transferee court and to propose ways to resolve them. If the transferee judge views establishing separate tracks for the different retailers appropriate, then he can do so, but that is a matter dedicated to his discretion.
On the basis of the papers filed and the hearing session held, we find that the actions listed on the attached schedules involve common questions of fact and that centralization will serve the convenience of the parties and witnesses and promote the just and efficient conduct of this litigation. ‘ All of the actions present common factual questions arising from the New York attorney general investigation allegedly determining in February 2015 that certain store brand herbal supplements sold by Walgreens, Wal-Mart, Target, and GNC did not contain the herbs advertised on the label and instead contained fillers or contaminants.6 Centralization will eliminate duplicative discovery; prevent inconsistent pretrial rulings, including with respect to class certification; and conserve the resources of the parties, their counsel, and the judiciary.
The Northern District of Illinois is an appropriate transferee district for this litigation. This district provides a convenient and accessible forum for actions filed throughout the country regarding products sold nationwide. Walgreens, Wal-Mart, Target, and NBTY support this district, and GNC supports it in the alternative. Responding plaintiffs in over 20 actions also support this district as their first or second choice. A significant number of actions are pending in this .district, which is also where the Walgreens defendants are based. Judge John W. Darrah is an experienced transferee judge and currently presides over one action involving all four retailers. We are confident that he *1377will steer this litigation on a prudent course.
IT IS THEREFORE ORDERED that the actions listed on Schedules A, B, C, and D, and pending outside the Northern District of Illinois are transferred to the Northern District of Illinois and, with the consent of that court, assigned to the Honorable John W. Darrah for coordinated or consolidated pretrial proceedings.
IT IS FURTHER ORDERED that plaintiffs’ motions for centralization in MDL Nos. 2619, 2620, 2621, and 2622, are denied in all other respects.
IT IS FURTHER ORDERED that MDL No. 2619 is renamed In re: Herbal Supplements Marketing and Sales Practices Litigation.
