I think you are conflating a couple of ideas in your comment making it a bit muddled in my mind. Actual incidents of product contamination (originating in any country/manufacturer) shouldn't be characterized as "conspiracy theories", that is just inaccurate, IMHO. Drawing general conclusions about a particular country or industry based on media reports should be done very cautiously (confirmation bias, non-random samples, media inaccuracy on details etc.) but even then the details of the assertion are going to be important in labeling something a "conspiracy theory". Could just be statistical illiteracy, sloppy reporting, click-bait stories, etc. I think you were concerned about a single data point being extrapolated into a general assertion with no evidence -- that happens all the time in the media but I don't think that phenomena is best described as a "conspiracy theory".
