In the case of food poisoning by injection for foods packaged in polypropylene bags, the shape of the hole on the bag is compared with that of the controlled holes to detect the type of needle that was used.
A method was developed to make controlled holes by needles at various angles on polypropylene bags and many images of controlled holes were obtained.
Almost all controlled holes were accompanied by scratch marks. There were some correlation between injection needle diameters and scratch widths.
The images of controlled holes are useful for checking rupture lines of suspected sample film and estimating the angle of the injection needle. Also the images are useful to make control samples efficiently. The reported method is simple so that one can make a variety of controlled holes depending on the suspected needles or suspected films.
