Yes, based on limited information and PFAS water levels found in Washington, we don't expect produce to be a significant source of PFAS exposure. The health benefits of gardening may outweigh any health risks.
It is possible for some PFAS from contaminated soil or irrigation water to reach edible parts of plants. However, a garden study by the Minnesota Department of Health showed that for PFAS with health-based guidelines, levels did not exceed health-based guidelines for exposure. Research on this question is emerging. If you are concerned, here are some ways to minimize exposure:
There are no current standards for allowable PFAS in commercial produce. If you raise and sell crops, contact the Washington State Department of Agriculture for their most updated guidance.

A blood test for PFAS can tell you how much of each PFAS measured is in your blood. It can allow you to compare your PFAS levels to national norms or with other communities. Blood testing also helps us measure PFAS exposure for community studies on health outcomes.
At this time, we don't know what the PFAS levels in blood mean in terms of individual health risk. The test results can't be used to diagnose current health problems, predict future health problems, or indicate a specific course of treatment for the patient.
If you have specific health concerns, please consult with your health care provider.
If PFAS are above health advisory levels in your drinking water, we recommend that you switch to an alternative source of drinking water and continue to breastfeed your baby. Given the scientific understanding at this time, the benefits of breastfeeding outweigh any potential risks of PFAS exposure through breast milk. Talk to your health care provider if you have concerns about PFAS and breastfeeding.

No, you cannot boil PFAS out of water.
