A Florida food company has been notified by the FDA after a facility inspection caused by a multistate outbreak of Listeria monocytogenes. Infections associated with ice cream supplied to facilities of Big Olaf Creamery LLC.

According to the Centers for Disease Control and Prevention (CDC), 28 patients in 11 states were infected with the outbreak strain of Listeria monocytogenes. One patient died and one pregnant patient had a miscarriage. On July 13, 2022, the company recalled all ice cream products and Big Olaf brand ice cream through June 30, 2022 due to possible contamination with Listeria monocytogenes.

In its December 9, 2022 warning letter, the FDA described an inspection of Big Olaf Creamery LLC, located in Sarasota, Florida, from July 19 through September 1, 2022.

An FDA inspection revealed that the company was not in compliance with FDA regulations, resulting in the issuance of FDA Form 483. Some of the serious violations are:

Multistate Outbreak of Listeriosis Associated with Big Olaf Ice Cream
CDC, FDA, the Florida Department of Health, and the Florida Department of Agriculture and Consumer Services (FACS) investigated this multistate outbreak of Listeria. Monocytogenes infection associated with ice cream manufactured by Big Olaf Creamery. The investigation found that at least 28 patients in 11 states were infected with the outbreak strain of Listeria monocytogenes. Whole-genome sequencing was performed on Listeria monocytogenes from 28 sick people, showing that Listeria monocytogenes are genetically closely related to each other, suggesting that consuming the same food by sick people could lead to disease. Fourteen patients were Florida residents, and 11 were reported to have traveled to Florida before onset of illness. Of her 28 sick people with available information, 27 were hospitalized and 7 sick were pregnant or their newborns. Her 1 death and her 1 miscarriage attributed to listeriosis have been reported.

In the interviews, the sick people answered questions about the foods they ate and other exposures in the month before they became ill. The person specifically reported eating Big Olaf ice cream or eating at a location provided by the Big Olaf Creamery in the month before the illness began. In addition, she reported that one patient had eaten ice cream more than a month before the onset of symptoms. It can take up to 70 days for him to develop symptoms of listeria infection.

According to the warning letter, comprehensive epidemiological data, disease subcluster information, and food histories of travelers to Florida suggest that Big Olaf Creamery ice cream is the cause of disease in this outbreak of Listeria monocytogenes infection. It strongly indicates that

Additionally, on July 7 and 9, 2022, FACS collected samples (environmental swabs and finished packaged ice cream products from Big Olaf’s production environment). In this sample, 10 environmental swab isolates and 20 ice cream product isolates matched his 2022 clinical outbreak isolates and 2021 based on his WGS analysis.

The presence of Listeria monocytogenes in the company’s facilities and its products demonstrates insufficient sanitation efforts to effectively control pathogens in facilities and prevent food contamination. is important in that Proper control of Listeria monocytogenes in food processing environments requires knowledge of the organism’s unique characteristics and implementation of the corresponding hygiene practices necessary to control this pathogen.

Hazard Analysis and Risk-Based Preventive Controls (21 CFR Part 117, Subpart C)

1. Failure to develop or have developed and implemented a food safety plan when required. Development of the food safety plan shall be overseen by one or more Preventive Controls Qualified Individuals (PCQIs), as appropriate. A company’s food safety plan must also include:

1) written hazard analysis;

2) written preventive controls;

3) a written supply chain program;

4) recall plan;

5) written procedures for monitoring the implementation of preventive controls;

6) written corrective action procedures;

7) written verification procedures;

However, the company did not have a food safety plan with the necessary elements.example (Edited) Determine whether various RTE ice cream products are manufactured, processed, packed, or held at your facility for hazards that require preventive controls.

In addition, preventative measures are taken to ensure that the hazards requiring preventive controls are substantially minimized or prevented and that RTE ice cream products manufactured, processed, packed, or held at the facility are not adulterated or fraudulently branded. Did not identify and implement controls. .

Preventive controls include process controls, food allergen controls, sanitation controls, supply chain controls and recall plans, depending on the facility and food. Given the nature of the preventive control and its role in the facility’s food safety system, the preventive control should include preventive control control components (monitoring, verification, and corrective action) as necessary to ensure the effectiveness of the preventive control. subject to You should also verify that the preventive control can adequately control the hazards, depending on the nature of the preventive control and its role in the facility’s food safety system. Specifically for RTE ice cream products:

Your supply chain program must include using approved suppliers and conducting supplier verification activities.
