“…Ultraviolet light has been studied widely to use as an activator to trigger the oxygen scavenging reaction to prevent the initial reaction with atmospheric oxygen (Albert and Rooney 2004). Byun et al (2011) proposed the use of ␣-tocopherol and a transition metal coupled with thermal processing as a potential oxygen scavenger.…”

“…However, nowadays, many consumers have a negative view of the term ''iron-based." Therefore, Byun et al (2011) studied the development of na oxygen scavenger using a natural compound: -tocopherol. A natural free radical scavenger, -tocopherol, and a transition metal in an oxygen scavenging system were evaluated as a possible oxygen scavenger.…”

“…Vacuum packaging has been widely used to eliminate oxygen in the package prior to sealing. However, the oxygen that permeates from the outside environment into the package through the packaging material cannot be removed by this method (Byun et al, 2011).…”

“…1). The most common active ingredient in food-grade oxygen scavenging systems is reduced iron, used for its ability to consume oxygen via conversion to iron oxide [1]. Reduced iron is a term generally used to refer to the end product of iron oxide that has been reduced with hydrogen or carbon monoxide.…”

Oxygen absorbers are commonly used in packages of dried or dehydrated foods (e.g., beef jerky, dried fruit) to prolong shelf life and protect food from discoloration and decomposition. They usually contain reduced iron as the active ingredient although this is rarely stated on the external packaging. Although reduced iron typically has minimal oral bioavailability, such products are potential sources of iron poisoning in companion animals and children. We present a case of canine ingestion of an oxygen absorber from a bag of dog treats that resulted in iron intoxication necessitating chelation therapy. A 7-month-old female Jack Russell terrier presented for evaluation of vomiting and melena 8-12 h after ingesting 1-2 oxygen absorber sachets from a package of dog treats. Serum iron concentration and ALT were elevated. The dog was treated with deferoxamine and supportive care. Clinical signs resolved 14 h following treatment, but the ALT remained elevated at the 3-month recheck. The ingestion of reduced iron in humans has been reported to cause mild elevation of serum iron concentration with minimal clinical effects. To our knowledge, no cases of iron intoxication following the ingestion of oxygen absorbers have been reported. The lack of ingredient information on the packaging prompted analysis of contents of oxygen absorber sachets. Results indicate the contents contained 50-70% total iron. This case demonstrates that iron intoxication can occur following the ingestion of such products. Human and veterinary medical personnel need to be aware of this effect and monitor serum iron concentrations as chelation may be necessary.
