This is an action of tort to recover for personal injuries caused by a piece of tin embedded in a loaf of bread, alleged to have been manufactured by the defendant.- In the Municipal Court the judge found for the plaintiff and reported the case to the Appellate Division, which dismissed the report; and the defendant appealed. The only issue presented is whether the evidence, offered to show that the defendant was the manufacturer of the loaf of bread, was admissible, and whether the court was justified in finding upon the evidence that the food containing the foreign substance which injured the plaintiff was manufactured by the defendant.
The testimony to which reference has been made tended to prove that the loaf came in a sealed wrapper upon which appeared the words: “Massachusetts Baking Company,” “White Rose Bakery New England Office, Boston,” also a statement of the weight as one pound, four ounces and the words “Trade Mark Registered IT. S. Pat. Off.” This wrapper had been destroyed, but a wrapper was introduced in evidence which the witness stated to be similar in all respects except that instead of the name “Massachusetts Baking Company” which was on the plaintiff’s loaf there appeared on the wrapper in evidence the present trade name of the defendant. It was agreed by counsel at the trial that the name appearing upon the plaintiff’s loaf was the trade name of the defendant at the time the loaf was purchased by the plaintiff.
A manufacturer is liable “to third persons for negligence in the preparation of food for human consumption: whether the unfitness of the food be due to deleterious ingredients, or to the presence of a foreign substance.” Tonsman v. Greenglass, 248 Mass. 275, 277. A jury may infer from the fact that a piece of metal is embedded in the loaf that it got in during manufacture when the dough was soft, and that its presence was due to the negligence of the baker or manufacturer. Tonsman v. Greenglass, supra, page 278. DeGroat v. Ward Baking Co. 102 N. J. L. 188. See Richenbacher v. California Packing Corp. 250 Mass. 198.
The plaintiff was bound to prove that it was more probable *519that the damage was due to negligence of the defendant than to some other cause. Noble v. American Express Co. 234 Mass. 536. Crisafi v. Sells Floto Circus, ante, 120. The weight printed on the loaf was not one of the units referred to in G. L. c. 94, § 7, and because of the statutory provision, G. L. c. 94, § 8, the manufacturer had no right to sell a loaf of bread of the weight this loaf purported to have without placing his name thereon or upon the wrapper in which it was contained. No one except the defendant had the right to use its trade name. U. S. Comp. Sts. (1916) §§ 9485, 9504. In the absence of any evidence tending to show that the defendant’s trade name was being wrongfully used, the inference could be drawn that the name was used by the defendant in compliance with the statutory requirement and that the defendant was the manufacturer of the bread. It also could have been found that the piece of metal was in the bread when it was manufactured, and that its presence was attributable to the negligence of some one for whose act the defendant is responsible.
Order dismissing report affirmed.
