The CDC said a Salmonella outbreak linked to broccoli sprouts and microgreens grown from a contaminated New Zealand seed lot was over, with 34 sick in six states and 215 cases recalled. What should Thai salad shops prepare?
The CDC's final update on 4 November 2026 reported 34 cases in six states with three hospitalised, with illness onset from 7 July to 11 September 2026.
The source was broccoli sprouts and microgreens grown from a contaminated seed lot imported from New Zealand; Evergreen Fresh Sprouts recalled 215 cases on 10 September and the seed supplier recalled the lot.
Thai salad shops, health-food restaurants and juice bars serve uncooked sprouts and greens, so pathogens from seeds or produce reach customers directly. Traceable suppliers, lot records, separate prep areas, standard washing and sanitising surfaces with food-safe products reduce risk.

Before: No one knew which lot the sprouts came from when the recall hit.
After: Lot records, separate areas and immediate removal on recall.
If buying equipment is not practical or the area is too large, use the World Health Disinfection disinfection service or ozone treatment service. The team wears full protective equipment, chooses products to suit the germ and surface, and reports after the job.
Q: Why are sprouts risky? A: Sprouts grow in warm, humid conditions that suit bacteria and are often eaten raw; here the contamination came from the seed.
Q: How long before the area can be used? A: After ULV fogging, areas are typically usable about 30 minutes later. For ozone treatment, no people or pets may be inside and the room must be ventilated before use.
Q: Can I get a tax invoice? A: Yes. Tax invoices are issued and 3% withholding tax is supported. Call 065-556-6294 or LINE @whd268.
Follow disease updates from Thailand's Department of Disease Control (hotline 1422) and the World Health Organization. Disinfection reduces germs in the environment and is not medical treatment; anyone with symptoms should see a doctor.
The broccoli sprout case shows contamination can start at the seed. Traceable, systematically clean shops respond to recalls immediately.
