WHO standard of heavy metal in food sample?

The World Health Organization (WHO) has established a number of standards for heavy metals in food samples. These standards are designed to protect human health from the potential harmful effects of heavy metals.

The following table lists the WHO standards for some of the most common heavy metals found in food:

| Heavy Metal | Maximum Level (mg/kg) |

|---|---|

| Arsenic | 0.1 |

| Cadmium | 0.001 |

| Lead | 0.01 |

| Mercury | 0.001 |

These standards are based on the latest scientific evidence and are subject to change as new information becomes available.

It is important to note that these standards are not absolute limits. They are rather guidelines that should be used in conjunction with other factors when determining the safety of a particular food sample.

For example, the presence of a heavy metal in a food sample does not necessarily mean that the food is unsafe to eat. The amount of the heavy metal, the form of the heavy metal, and the other ingredients in the food all need to be taken into consideration when making a risk assessment.

If you have concerns about the levels of heavy metals in your food, you can contact your local health department or food safety agency for more information.
