Algae Bloom Being Monitored for Effect on Livestock


Based on test results reported on July 12th, the level of cyanotoxins in Utah Lake is NOT considered a health threat to livestock at this time.  According to Assistant State Veterinarian, Dr. Chelsea Crawford, cyanotoxin levels in the lake may change rapidly, and livestock and pet owners should monitor local news media for information.

The Utah Department of Agriculture and Food (UDAF) will continue to track monitoring data and provide direction to the agricultural community as the cyanotoxin concentrations change.

The UDAF advises livestock owners to locate an alternative source of water should cyanotoxins rise to unhealthy levels in the future.

The algae cells that can produce toxin are present in significant numbers in certain parts of the lake even though they are not producing dangerous levels at this time. In some cases, animals may choose a cyanobacteria source over clean water even if a clean water source is available. Animals may eat mats of cyanobacteria slime. In these cases, animals should be restricted from areas of concentrated cyanobacteria and be provided a clean source of drinking water.
