Cut flowers and vase water can contain bacteria and fungi, but their presence does not show that a bouquet will make someone sick at home. The available evidence does not quantify the chance of illness in ordinary households. CDC guidance is more cautious in certain healthcare settings, especially where patients are severely immunocompromised.
What microbes can be on flowers or in vase water?
Flower-vase water can support diverse bacteria, particularly when it is not changed regularly. CDC summarizes studies reporting concentrations from 104 to 1010 colony-forming units per milliliter (CFU/mL), especially when water was changed infrequently. That is a measure of microbes in sampled water, not a measure of the chance that someone will become ill.
A 1991 study by K. S. Kates and colleagues found 41 bacterial species across 60 flower-vase-water samples. It reported a mean total aerobic bacterial count of 4.5 × 108 organisms per 500 mL. These are results from the study’s samples, not an estimate of what is typical in a home today. Read the study record on PubMed.
CDC also notes that flowers and ornamental plants may serve as reservoirs for Aspergillus and other fungi, and that spores can disperse. This matters most in care environments where patients are highly vulnerable; it does not establish that an ordinary household bouquet poses a measurable infection risk.

Do cut flowers make people sick at home?
The available evidence does not establish how often, or whether, ordinary household members become ill from cut flowers. A large microbial count is not an illness count: infection risk depends on factors beyond whether microbes are present, and the cited studies do not measure household illness outcomes.
CDC summarizes healthcare evidence as showing “minimal or no evidence” that plants in patient-care areas increase healthcare-associated infection among immunocompetent patients. One study involving a limited number of surgical patients found no correlation between bacterial isolates from areas near flowers and postoperative infections. Those findings are reassuring for the settings reviewed, but they do not prove zero risk in every home or for every person. CDC infection-control guidance

Why are flowers restricted in some healthcare settings?
Healthcare precautions are tailored to patients’ vulnerability and the consequences of exposure. CDC advises efforts to exclude flowers and plants from areas caring for immunosuppressed patients, including hematopoietic stem-cell transplant units. This is a targeted infection-control measure for specialized care, not a blanket recommendation that people avoid flowers in their homes.
If someone in your household is severely immunocompromised, ask their clinical team whether flowers are appropriate in their specific circumstances. The CDC guidance concerns healthcare environments and should not be treated as individualized medical advice for a home.

How should you handle flowers and vase water?
Basic hygiene is a sensible way to limit contact with microbes during flower care:
- Wash your hands after handling flowers or their vase water.
- Change the water regularly and clean the vase when refreshing an arrangement.
- CDC’s patient-care precautions specify changing vase water every two days and cleaning and disinfecting vases after use. That interval is healthcare guidance, not a household medical requirement.
Flower food is intended to help flowers last longer and reduce bacterial clouding in the water. CDC does not establish that flower food prevents human illness. Do not add household disinfectants or spray flowers as infection-prevention measures; the cited guidance does not show that these practices protect household members.

What the evidence can—and cannot—tell you
The available evidence combines healthcare infection-control guidance with studies of microbes in sampled vase water. It supports the conclusion that microbes can be present and that extra precautions are appropriate around certain highly vulnerable patients. It does not provide a household illness rate, prove that a bouquet is risk-free, or establish that a particular flower-care product prevents infection.
