FDA also conducted a complaint investigation from February 11 through February 12, 2019, during which FDA obtained samples of your canned dog food.<\/p>\n<p>The inspections and the investigation confirmed that animal food products with unsafe levels of vitamin D were manufactured and marketed by your firm.\u00a0 You determined the unsafe levels of vitamin D were the result of an ingredient that you received and accepted in a manner not in accordance with your receiving procedures, and that was subsequently incorporated in the animal food products. The unsafe amounts of vitamin D cause your products listed below to be adulterated because they bear or contain a food additive that is unsafe within the meaning of the Federal Food, Drug, and Cosmetic Act (FD&amp;C Act).<a id=\"footnoteref1_zw42wtm\" class=\"see-footnote\" title=\"Section 402(a)(2)(C)(i) of the FD&amp;C Act [21 U.S.C. \u00a7 342(a)(2)(C)(i)] and section 409 of the FD&amp;C Act [21 U.S.C. \u00a7 348].\" href=\"https:\/\/www.fda.gov\/inspections-compliance-enforcement-and-criminal-investigations\/warning-letters\/hills-pet-nutrition-inc-576564-11202019#footnote1_zw42wtm\">1<\/a><\/p>\n<p>Furthermore, the inspection revealed violations of FDA\u2019s Hazard Analysis and Risk-Based Preventive Controls requirements for animal food found in Title 21 of the Code of Federal Regulations, part 507, subpart C (21 CFR part 507, subpart C).

On January 31, 2019 your firm initiated a recall (RES# 82018) of twenty-five (25) different canned dog food products manufactured by your firm. On March 20, 2019 your firm determined that additional products were affected. As a result, approximately twenty (20) additional lots of product previously listed in the original recall were added, and the recall was expanded to include eight (8) new products of canned dog food. On May 20, 2019 your recall was expanded yet again to include an additional lot. A comprehensive list of your recalled products can be found on FDA\u2019s website at\u00a0<a href=\"http:\/\/www.fda.gov\/\">www.fda.gov<\/a>.<\/p>\n<p><u><strong>Adulterated Animal Food &#8211; Unapproved Food Additive<\/strong><\/u><br \/>\nOn February 11 and 12, 2019, during a complaint investigation, FDA collected for vitamin D analysis two samples of your Hills Prescription Diet Digestive Care i\/d Low Fat (SKU Number 10423) canned dog food. These samples were part of the lots covered by your recall. Testing of the products revealed the following results:<\/p>\n<ul>\n<li>Lot code BEST BEFORE 10 2020, T1911124 3912, found 100,170 to 107,282 IU\/kg of vitamin D in your canned dog food.<\/li>\n<\/ul>\n<ul>\n<li>Lot code BEST BEFORE 10 2020, T1911125 3912, found 102,829 to 102,346 IU\/kg of vitamin D in your canned dog food.<\/li>\n<\/ul>\n<p>A food additive is a substance that becomes a component of food unless it is generally recognized, among experts qualified by scientific training and experience to evaluate its safety, as having been adequately shown through scientific procedures to be safe under the conditions of its intended use.<a id=\"footnoteref5_tlu8t6n\" class=\"see-footnote\" title=\"See definition of \u201cfood additive\u201d in Section 201(s) of the FD&amp;C Act [21 U.S.C \u00a7 321(s)].

At these levels, vitamin D is not generally recognized as safe; therefore, it is a food additive. Under section 409 of the Act (21 U.S.C. \u00a7 348), a food additive is unsafe unless a regulation is in effect that prescribes the conditions under which the additive may be safely used, and the additive and its use or intended use are in conformity with that regulation. We are not aware of any regulation that would allow the use of vitamin D at the levels found in the above-referenced canned dog food. Therefore, the vitamin D is an unsafe food additive and the canned dog food containing these elevated levels of vitamin D is adulterated under section 402(a)(2)(C)(i) of the FD&amp;C Act [21 U.S.C. \u00a7 342(a)(2)(C)(i)].<\/p>\n<p><u><strong>Adulterated Animal Food &#8211; Hazard Analysis and Risk-Based Preventive Controls Requirements<\/strong><\/u><br \/>\nDuring our inspection of your facility, FDA Investigators noted violations of the Hazard Analysis and Risk- Based Preventive Controls requirements for animal food found in Title 21 of the Code of Federal Regulations, part 507, subpart C (21 CFR part 507, subpart C).\u00a0 These violations render your animal food products adulterated under the FD&amp;C Act.<a id=\"footnoteref9_appsgo0\" class=\"see-footnote\" title=\"Section 402(a)(4) of the FD&amp;C Act [21 U.S.C. \u00a7 342(a)(4)] and 21 CFR 507.1(a)(1).\" href=\"https:\/\/www.fda.gov\/inspections-compliance-enforcement-and-criminal-investigations\/warning-letters\/hills-pet-nutrition-inc-576564-11202019#footnote9_appsgo0\">9<\/a>\u00a0Violations observed during the inspection include, but are not limited to, the following:<\/p>\n<p>Your firm did not sufficiently assess the probability that a vitamin D toxicity or deficiency hazard will occur in the absence of a preventive control as required by 21 CFR 507.33(c)(1).<\/p>\n<p>Specifically, your firm uses vitamin premix in the manufacture of animal food products, but your firm failed to implement your prerequisite program to ensure that the vitamin premix did not contain an excess of vitamin D, which is a known or reasonably foreseeable hazard that could occur in the absence of a preventive control.\u00a0 As stated in your food safety plan\u2019s risk assessment matrix for your vitamin premix, you were relying on a\u00a0<strong>(b)(4)<\/strong>\u00a0to prevent nutrient deficiencies and toxicity hazards\u00a0<strong>(b)(4)<\/strong>, which you classified as a high risk chemical hazard. You noted that \u201c[i]f the raw materials or other ingredients do not contain nutrients at the expected levels, this may result in either a nutrient deficiency or toxicity hazard when the ingredient is incorporated into the animal food based on a preset formulation.\u201d Your food safety plan also stated that \u201c[c]hemical hazards identified as high risk require the hazard be analyzed and be within acceptable limits prior to unloading the specific raw material into the manufacturing facility.\u201d<\/p>\n<p>However, the vitamin premix was not analyzed and subsequently reviewed to ensure that the vitamin D added to final products from the premix would meet your firm\u2019s pre-set formulation. Your ingredient specification for the vitamin premix included a target specification for vitamin D and states that the \u201cSupplier must include Certificate of Analysis\u00a0<strong>(b)(4)<\/strong>,\u201d but your firm did not obtain Certificates of Analysis (COA) upon receipt\u00a0<strong>(b)(4)\u00a0<\/strong>of vitamin premix from your supplier. Your firm also failed to test, evaluate against your specification, and subsequently reject the vitamin premix containing excess vitamin D, as required by your food safety plan.\u00a0 As a result, you used vitamin premix containing a concentration of vitamin D that was outside your specification.<\/p>\n<p>As a result of your failure to follow your food safety plan, the hazard of vitamin D toxicity was not adequately managed at your receiving step.\u00a0 Therefore, you did not reduce the probability that the hazard would occur in the absence of a preventive control. As a result of your failure to consistently implement your pre-requisite program, a systematic failure of your food safety plan occurred that resulted in the recall of canned dog food as identified above.\u00a0 The systematic failure also resulted in adulterated animal food, as described above.<\/p>\n<p><strong>Corrective Actions<\/strong><\/p>\n<p>We acknowledge your promised corrective actions in your written responses dated March 12, 2019, May 23, 2019, and August 30, 2019 to the Form FDA 483, which include implementing a\u00a0<strong>(b)(4)<\/strong>\u00a0Certificate of Analysis (COA) requirement for vitamin premixes and trace mineral premixes, revising the Receiving Procedure to address the need for\u00a0<strong>(b)(4)<\/strong>\u00a0COAs\u00a0<strong>(b)(4)<\/strong>, training personnel on the revised Receiving Procedure, integrating COA requirements into an internal system so that incoming vitamin and trace mineral premix ingredients cannot be received without conforming COAs, conducting an onsite audit of your supplier\u2019s facility, revising your Food Safety Plan, and implementing a process preventive control for the\u00a0<strong>(b)(4)<\/strong>\u00a0steps to enhance control of the misformulation hazard.<\/p>\n<p>We are unable to assess the adequacy of your corrective actions because many are preexisting procedures that were not followed consistently prior to the recall event. For example, your requirement for vitamin premixes with vitamin D to have a COA\u00a0<strong>(b)(4)<\/strong>\u00a0was documented in your ingredient specification before the recall.\u00a0 This was further confirmed by your firm\u2019s special instructions to your supplier\u00a0<strong>(b)(4)<\/strong>.\u00a0 In your response to the Form FDA 483, you stated that your food safety plan was not intended to cover \u201cmisformulation\u201d by your supplier.\u00a0<strong>(b)(4)<\/strong>\u00a0and noted that \u201c[n]utrient deficiency or toxicity hazards can be the result of incorrect levels of nutrients in incoming raw materials or ingredients.\u201d<\/p>\n<p>Your response states that your firm is now implementing a process preventive control at the\u00a0<strong>(b)(4)<\/strong>\u00a0step; however, you did not provide adequate documentation demonstrating the implementation and effectiveness of the preventive control to include the associated management components as required by 21 CFR 507.39 and therefore we are unable to determine the adequacy of this corrective action.<\/p>\n<p>The corrective action of a \u201cprocess preventive control\u201d at your\u00a0<strong>(b)(4)<\/strong>\u00a0step\u00a0<strong>(b)(4)<\/strong>. However, it does not address the root cause of this incident, which was accepting an ingredient without confirming that it contained vitamin levels that were within specification as required by your procedures.<\/p>\n<p>FDA will verify your proposed voluntary corrective actions during a future inspection of your firm.<\/p>\n<p><strong>Conclusions<\/strong><\/p>\n<p>The violations cited in this letter are not intended to be an all-inclusive list of violations that exist at your facility.\u00a0 You are responsible for investigating and determining the causes of the violations identified above and for preventing their recurrence or the occurrence of other violations.\u00a0 It is your responsibility to ensure your firm complies with all requirements of federal law, including FDA regulations.\u00a0 You should take prompt action to correct the violation cited in this letter.

For a domestic facility, FDA will assess and collect fees for reinspection-related costs from the responsible party for the domestic facility. The inspection noted in this letter identified non-compliance materially related to a food safety requirement of the FD&amp;C Act.\u00a0 Accordingly, FDA may assess fees to cover any reinspection-related costs.<\/p>\n<p>Your firm\u2019s response should be sent to Danial S.
