I would assume this would fall under product liability laws. However I am not a lawyer and this sure as heck is not legal advice.

Products liability refers to the liability of any or all parties along the chain of manufacture of any product for damage caused by that product. This includes the manufacturer of component parts (at the top of the chain), an assembling manufacturer, the wholesaler, and the retail store owner (at the bottom of the chain).
Products liability claims can be based on negligence, strict liability, or breach of warranty of fitness depending on the jurisdiction within which the claim is based.
Translated to products liability terms, a defendant is liable when it is shown that the product is defective. It is irrelevant whether the manufacturer or supplier exercised great care; if there is a defect in the product that causes harm, he or she will be liable for it.
I assume when they use manufacturer in the last paragraph they mean everyone in the chain as described previously.
