“Processed meat is classified in the same International Agency for Research on Cancer (IARC) carcinogenicity category as tobacco smoking (cigarettes).”
IARC and WHO sources explicitly place processed meat consumption and tobacco smoking in the same IARC Group 1 category, meaning there is sufficient evidence they can cause cancer in humans. The claim is accurate as stated. The main caveat is that sharing a category does not mean they pose the same level of risk.
“The World Health Organization (WHO) classified processed meats, including deli ham, as Group 1 carcinogens.”
This claim is substantively accurate. In October 2015, IARC — the cancer research agency of the WHO — classified processed meat as a Group 1 carcinogen, and explicitly listed "ham" as an example. WHO itself communicates this classification on its own website. Saying "WHO classified" is reasonable shorthand, though technically the classification comes from IARC's Monographs program. "Deli ham" falls under the processed meat category rather than being individually evaluated. The core claim holds up well.
