An outbreak of Listeria monocytogenes linked to enoki mushrooms that spanned more than three years and led to four deaths appears to be over, according to the Food and Drug Administration.

Although the onset dates started in November 2016 and the last recorded case was reported in December 2019, the FDA continued to warn consumers this spring, with imported enoki mushrooms from the Republic of Korea (South Korea) testing positive with the same strain tied to the earlier deaths.

In all, 36 people were sick, with 31 requiring hospitalization, according to the FDA.

The federal agency issued warnings in March and April, advising people in the Listeria monocytogenes high-risk group, including the elderly and pregnant women, to avoid all enoki mushrooms from South Korea, regardless of distributor or brand.

The mushrooms named in the three recalls were from Green Co. Ltd. in South Korea.
