Meat is having a terrible, no good, very bad week. And it’s only Monday.

Reddit user Wiener_Holder_2020 posted in the Not The Onion community about a food analysis report that discovered traces of human DNA in about 2 percent of the 345 hot dogs and sausages that were tested. The study reported that more than 14 percent of the samples “were problematic in some way.” And no, the writers weren’t referring to the hot dogs’ views on race and gender.

(Interestingly, the report, which was conducted by Clear Food, found meat in 45 percent of the vegetarian samples. Two-thirds of those samples also had human DNA in them.)

But meat’s biggest hit came Monday.

That’s when the World Health Organization labeled processed meat a carcinogen and hinted that it would be doing the same for red meat as well. This designation, which Reddit user Ragnarokcometh posted in the World News community, would lump meat in the same category as other cancer-causing agents, such as cigarettes and asbestos.

WHO has been posting the findings from the report, which was conducted by the International Agency for Research on Cancer, on Twitter. Here’s a crib sheet on what you need to know about this announcement.

What Kind of Meat?

Meat—processed or otherwise—covers a lot of food ground. So what kind of cuts fall under WHO’s designation? When it comes to processed meats—these are meats with extended shelf lives thanks to smoking, curing, adding salt and preservatives, or using other methods, according to WHO—hot dogs; sausages; deli meats like ham, salami, and bologna; and, the holiest of holies, bacon are now considered cancer risks. Beef, lamb, veal, pork (sorry, it’s not considered “the other white meat” in this case), and other mammalian muscle meat fall in the red meat category, WHO reports.

What Kind of Cancer?

The report found that for every 50 grams of processed meat eaten daily, the chances of contracting colorectal cancer increase by 18%. And while colorectal cancer was the main concern when consuming red meat, other cancer risks also were evident.

Are There Other Risks?

No conclusions were reached by the report on whether high-temperature cooking increased cancer risks or if eating raw meat was safer.
