A Decade of Challenges The pet food industry increasingly faces challenges associated with a global supply chain, potential for contaminants, growing quality expectations, escalating regulatory scrutiny, more educated consumers and pet owner expectations. Globally, the incidence of pet ownership has increased with rising consumer income. More than ever before, pet owners believe that their pets
are family members who deserve nutrition comparable in quality to what they feed themselves. Since 2006, several high-exposure situations have occurred within the pet food industry that have brought an elevated level of consumer awareness and concern over the safety of pet food products.
In 2007, an economic adulteration of imported wheat gluten and rice protein concentrate with melamine and

cyanuric acid resulted in the recall of over 150 brands of pet food.1 It is believed that the contamination also led to a significant, untold number of cat and dog deaths.
Also in 2007, the FDA launched an investigation into the safety of duck, chicken and sweet potato jerky, mostly imported from China. Since the investigation began, there have been more than 6,200 pet illnesses reported and more than 1,140 docu-mented canine deaths.2 To date, the FDA has not determined the cause of the pet illnesses.
In addition, over the last 10 years, there has been a growing level of scrutiny over the microbiological safety of pet foods. As shown in Figure 1, in the last four years, greater than 75 percent of pet food recalls have been associated with suspected pathogen or mold contamination. A majority of these recalls have been related to salmonella, while the last two years have also seen a growth in recalls linked to Listeria.
A New Safety FocusThere has been an increased global response in reaction to and preventing recalls. As an example, in 2011, grow-ing consumer concerns over food safety led the FDA to enact the most sweeping reform to food safety in over 70 years.4 The Food Safety Modernization Act (FSMA) was designed to shift the focus of enforcing regulations surrounding contamination issues to preventing them. The legislation primarily focuses on the following areas: Prevention; Inspections, Compliance and Response; Import Safety; and Enhanced Partnerships.
The preventative control portion of this legislation requires human and animal food facilities to implement hazard analysis and risk-based preventative controls. This requires facilities to:
1. Evaluate hazards that could affect food safety2. Identify and implement preventative controls to
prevent hazards3. Monitor controls and maintain monitoring records4. Conduct verification activities
Agencies around the world have been establishing their unique standards and best practices regarding food safety. The European Union funded the European Food Safety Authority (EFSA), which was established in 2002 under the EU General Food Law–Regulation 178/2002, with the role of providing scientific advice and communi-cation on risks associated with the food and feed chain. EFSA operates independently of the European legislative and executive institutions (Commission, Council and Parliament) and EU Member States. As the risk assessor, EFSA produces scientific opinions and advice that form the basis for European policies and legislation.
In Brazil, MAPA (feed and agriculture food) and ANVISA (food) have some programs to control food safety; however, they follow different legislation to promote and coordinate activities related to the topics of veterinary and human pharmacovigilance, monitoring and control of antimicrobial resistance in animals, and violations of residues and contaminants (dioxins, heavy metals, pesticides, antibiotics, etc).

oxidative deterioration and microbial contamination of both their ingredients and the product sold to con-sumers. Failure to control oxidation of the fats and oils used in pet food can result in compromises to pet food nutritional quality and palatability. Autoxidation can be effectively managed through proper utilization of antiox-idants in pet food ingredients and throughout the entire pet food manufacturing processes.
In addition to threatening pet food safety, microbial hazards create public health risks related to the poten-tial for direct human contact with pet food. Effective management of these risks requires a thorough hazard analysis of the entire supply chain and production pro-cess, and that preventative controls are established. Any ingredient added to pet food kibble topically, after the extrusion kill step, increases risks. Since fats and oils are added post-extrusion, they can be managed by several methods: proper sanitation and hygiene procedures, heating fat to control microbial levels and the usage of ingredients proven to provide microbial control.
ALLINSUR™ A SeriesALLINSUR™ A series was developed to provide pet food manufacturers effective natural and synthetic solutions for controlling autoxidative deterioration, preserving freshness and influencing microbial risks in fats. A study was conducted at Log10, LLC to evaluate the effective-ness of ALLINSUR in influencing the growth of three
Salmonella strains (S. typhimurium, S. schwarzengrund, and S. infantis ) at 106 CFU/g. Figure 2 demonstrates the success of an ALLINSUR prototype in controlling microbi-al contamination in poultry fat. Studies show that adding ALLINSUR does not negatively impact the palatability of cat or dog food. ALLINSUR A Series Features & Benefits
• Provides effective oxidation management• Secondary benefit of influencing microbial levels in fats• Provides natural and synthetic preservation options • No observed “scorching” or black spots in fat• Neutral impact on canine and feline palatability
Raw Material Quality ManagementThere are significant risks to consider when managing raw materials used in the rendering process. Delays in processing raw materials can have consequences on both the oxidative and microbial quality of rendered fat and protein. Endogenous or exogenous enzymes (such as lipases or decarboxylase enzymes) can degrade raw material quality by catalyzing a number of reactions known to increase production of free fatty acids, biogenic amines and the lipid oxidation by-products. Raw material deterioration can also have significant negative conse-quences on the efficiency of plant operations. Degraded raw materials can cause a reduction in the heat transfer ability of the fat, which requires longer cooking times

that increase energy costs. The longer resonance time in the cooker will increase the level of product fines, which will decrease the efficiency of the presses. This causes a decrease in the fat yield and leaves more fat in the meal, which can result in meal that is difficult to handle.
ALLINSUR™ FS Series Freshness SolutionThe ALLINSUR™ FS product line is a highly effective blend of antioxidants and acidifiers designed to maintain the quality of raw material in the rendering industry. It aids in prolonging the freshness of raw materials by controlling oxidation and microbial degradation. Protecting the quality of raw materials helps to improve operational efficiency in the rendering plant to increases plant profitability, and achieve pet food manufacturers’ quality requirements. Figure 3 demonstrates the effectiveness of ALLINSUR FS in controlling microbial degradation of poultry viscera, as measured by control of histamine production.
ALLINSUR FS Features & Benefits• Innovative and optimal combination of antioxidant
and acidifiers• Reduces free fatty acid in animal fats and protein meals• Provides effective precooking oxidation management • Reduces biogenic amines in animal protein meals• Improves efficiency of rendering operations• Neutral effect on companion animal palatability
Pet Treat MarketIn nearly every pet food market around the world, the pet treat segment is experiencing tremendous growth. With the growing global trend of pet humanization, pet owners are increasingly pampering their dogs and cats by indulg-ing them with treats that offer healthy and wholesome characteristics. One specific aspect of this trend is that consumers are increasingly moving away from synthetic additives and demanding natural alternatives.

Pet Treat PreservationPet treats can be produced in a wide variety of product forms, many of which have an elevated microbial risk due to their potential to have high moisture content and elevated water activity (aw). Effective microbial shelf-life preservation is a critical factor in the long-term market success of these treats. Historically, mold inhibition solu-tions have been formulated with synthetic ingredients and there have been limited natural options.
PREVION™ VC DryPREVION™ VC Dry was developed to provide pet food manufacturers an effective, natural alternative to synthetic preservatives for extending the shelf-life of pet treats. Since it is a water soluble combination of buffered vinegar and citric acid in a powder form, it can be incorporated into brines, marinades, dry ingredient blends or directly into meats. Buffering improves product handling and minimizes corrosivity of ingredients. Most importantly, PREVION does not negatively impact the palatability of pet treats, maintaining a consistent flavor profile in treats.
PREVION VC Dry Features & Benefits• Contains buffered ingredients for safe handling• Maintains quality of pet treats• Provides natural treat preservation• Consumer-friendly labeling• Effective microbial shelf-life extension• No negative impact on palatability
Food safety in the pet food industry is a shared respon-sibility among renderers, ingredient suppliers, manufac-turers, distributors and even the pet owners who feed the final products to their companion pets. Ensuring the safety and quality of commercial pet foods is both a challenging and complex process. That’s why Kemin Nutrisurance makes every effort to provide technical advice and laboratory testing support to assist with optimum oxidation management, natural mold inhibition and microbial control for your rendered fats and protein meals, pet food and pet treats.

Kemin Nutrisurance products help address food allergies and intolerances By Andrew G. Yersin, PhD, and Ryan Guldenpfennig, DVM
Q: Why are low allergen diets such a hot topic in the pet food industry?A. Food allergies and intolerances, like gluten or dairy intolerances, are common mealtime considerations for an increasing number of families. With the increasing humanization of pets, this heightened awareness of intolerances in humans often leads to discussions among pet owners and the pet industry. As a result, the pet food industry is challenged to create innovative solutions that address pet intolerances to key ingredients.
Q: What is the difference between a food allergy and a food intolerance? A. It is important to differentiate between a food allergy and a food intolerance in pets. A food allergy is triggered when a pet’s immune system in the digestive tract reacts
Ingredients: Low Allergen Diets for Pets
to a fragment of food. The type of food that elicits the im-mune response is called an allergen and is typically made up of protein. Symptoms may involve the gastrointestinal (GI) system—vomiting, diarrhea, bloating. However, symptoms typically involve the skin, which often mani-fest as inflammation, itchiness, rashes and patches in a pet’s coat. Symptoms can also often result in secondary infections of the ears, feet and other parts of the body.
A food intolerance is caused by the inability of the digestive tract to digest a food substance in the diet, often due to a lack of a functional enzyme or specific chemical. Food intolerance is typically more persistent and less recognized in its appearance, and may be more difficult to diagnose than a food allergy. This makes the symptoms of food intolerance to vary greatly, and easily appear as the symptoms of a food allergy.(1,2,3)

Q. How can one use food trials to assess a food allergy or intolerance?A. Food trials allow veterinarians to assess if an animal response to a diet is due to a true allergen or to the inability to “tolerate” certain food components. Food trials may be conducted by using a limited ingredient diet (LID) or a diet using hydrolyzed ingredients.
An LID is composed of a single source of protein that is “novel” or new to the pet’s diet. The carbohydrate source is also limited to a single ingredient, as there may be residual plant proteins present. It is important that the pet is only fed a protein source that it has not encoun-tered before.4
The other option is to feed a diet comprising hydrolyzed ingredients. The proteins in the diet are broken down into amino acids and smaller peptide fragments with the use of enzymes or acids. While it is not possible to complete-ly remove all potential allergens, reducing the size of peptides greatly reduces the risk of an allergic response. Various studies and calculations have been performed to determine what size of peptide is small enough to avoid triggering an immune response.
Q. What is a Dalton?A. A Dalton is a unit of measurement used at an atomic scale and is abbreviated as Da. One Dalton is equivalent to one atomic mass unit (AMU). Recall that one atom of hydrogen is equal to one atomic mass unit containing one proton and one neutron. So, essentially, one atom of hydrogen=1 Da.
We tend to categorize the sizes of peptides, proteins and other molecules by the thousands of Daltons. One thousand Daltons is called a kiloDalton, written as 1 kDa. To put this in applicable terms, the average size of an amino acid, the building blocks for proteins, is 110 Dalton. As mentioned above, it is believed that in order to avoid triggering a response from an immune cell, the peptide chain must be smaller than 5 kDa.5
Q: How can the pet food industry deliver solutions for formulating therapeutic diets for pets with AFRs (Adverse Food Reactions)? A. There are two ways that the pet food industry can provide pet owners with therapeutic diets. The first is to provide diets consisting of simplified recipes of new ingredients (ingredients that a pet has not eaten before). This route has several potential hurdles.
First, the diversification of pet food over the last decade has brought a wide variety of new lines of pet foods and treats to the market. Boutique and big box stores are shelved with new formulations and ingredients to provide pet owners with a larger variety. While this is great for the pet, it makes it difficult to determine all of the potential sources of protein the pet has already been exposed to when trying to implement a food trial plan. Another risk is that a chronic exposure to any protein can eventually lead to an allergy. It does not happen often, but it is a consideration.
It is also important to note that some proteins in one species of plant or animal may be similar to another
INGREDIENTS: LOW ALLERGEN DIETS FOR PETS

species, triggering a similar allergic response. This is known as cross-reactivity. Common examples include al-lergies to chicken triggered by turkey or duck, or a peanut allergy that is triggered by other legumes or tree nuts.
Finally, producing enough of a novel protein that is sustainable and cost-effective may be a large challenge.
Another option is providing a diet consisting of hydro-lyzed protein sources, like Kemin Nutrisurance's spray-dried chicken liver hydrolysate product, PROSURANCE™ CHX Liver.HD. The hydrolyzation process modifies the physical characteristics of the protein molecules, making them smaller, altering their shape and potentially changing their flavor profile.
Q: Why are hydrolysates an excellent option for high-quality protein source for pets?A: Hydrolysis is a normal process in digestion. Our bodies (and our pets’ bodies) need to break down food particles into small enough particles to be absorbed through the protective barriers of the digestive tract. The food particles are broken down by a combination of phys-ical grinding and hydrolysis by enzymes and acids in the GI tract. When the GI tract is not performing optimally for any reason (AFR, parasites, stress, antibiotic-induced
dysbiosis, etc.), this digestive process may not be sufficient to utilize all of the nutrition present in a diet.
As mentioned above, a hydrolysate product, like PROSURANCE™ CHX Liver.HD, provides the amino acids that a pet needs for growth/maintenance from sources often used in non-hydrolyzed diets. The advan-tage of a hydrolyzed diet is that it makes the proteins more readily available to the digestive tract for absorption.
Hydrolyzation expands the pet industry’s ability to use well-balanced, nutritious ingredients that optimize pets’ health.
