The incident is the most serious case of grave-robbing in the West African state, the world capital of voodoo where most of the country's 9 million residents practice a benign form of the official religion.
Authorities in Dangbo, a village 10 km (6 miles) from the capital Porto-Novo, began an investigation after a mason working at the cemetery said he spotted several masked men digging up the graves, from which organs and skulls were removed.
The two printed signs have appeared in the Market Hill area in Sudbury.
The town council, which owns the displays, said it has not added the signs and does not know why anyone else would.
Jacqui Howells, deputy council clerk, said: "It's a mystery and we have no idea where the signs have come from."
The council has about 40 floral troughs in the area around the town hall and St Peter's church.
It said the troughs are too high for dogs to eat from, so the signs are not needed to warn owners.
The council said the winter pansies were not poisonous, so there was no health risk.
Ms Howells said: "It's not a publicity stunt by us, although it is good publicity for Sudbury before Christmas.
"I don't know what to make of the signs - people do some weird things."

Ukraine's prime minister, Mykola Azarov (back left), watches Jordi Sardà Bonvehí (front left), a man they thought was a representative of Spain's Gas Natural Fenosa, as he signs a deal to build a gas plant!
It was the deal of the century, a $1bn contract for a brand new gas plant that would rescue Ukraine from its dependence on energy supplied by Vladimir Putin's Russia.
Prime minister Mykola Azarov oversaw the signing ceremony as a video feed appeared to show welders already at work on the liquid gas plant and the representative of the Spanish company Gas Natural Fenosa, Jordi Sardà Bonvehí, put his name to the agreement.
Not until several days after the event on Monday did it emerge that no one at Gas Natural had heard of Bonvehí. "This person does not represent the company," a spokesman for the firm said.
"Gas Natural Fenosa has not signed any contract to invest in a LNG plant project in Ukraine," the company added. "Nor does it have representatives working in Ukraine on this issue."

The U.S. Coast Guard confirmed to Action News that the hazardous chemical vinyl chloride is leaking from derailed train in Paulsboro, New Jersey.
Emergency management officials issued the advisory to residents of Paulsboro, West Deptford and East Greenwich Township as a precaution.
At least one tanker car may contain vinyl chloride, Gloucester County Emergency Management director J. Thomas Butts told WPVI-TV.
TV helicopter footage showed at least two tankers in Mantua Creek and one hanging over a trestle, part of which is seemingly collapsed. The creek empties into the Delaware River just across from Philadelphia International Airport.
The Environmental Protection Agency said short-term exposure to high levels of vinyl chloride can cause dizziness and drowsiness.
A spokesman for the state Environmental Protection Department says officials are trying to determine what the cars were carrying.
The Gloucester County Times says 18 people are reported to be having difficulty breathing.
It's not clear what caused the derailment.
Calls to Conrail have not been returned.
Iranian and Turkish officials in a series of meetings in Istanbul are due to explore avenues for further increase in economic cooperation between the two countries.
An Iranian trade delegation from the Northern Semnan province's Chamber of Commerce, Industry and Mine departed on Wednesday for Istanbul to expand the province's economic cooperation and trade with Turkey.
Members of the team will hold talks with their counterparts and partners to promote economic cooperation and trade during the one week visit to Turkey.
They will visit Polytan company in Istanbul as the largest Polymer company and hold talks with the Board of Directors of Etishkan Company which produces plasters for construction projects.
According to the figures released by the Turkish Statistical Institute, Iran became Turkey's third biggest business partner with a trade exchange of $17.52bln since the beginning of the current Iranian year (started on March 20, 2012).
Turkey imported $8.94 billion in goods from Iran, and exported $8.58 billion in goods to the Islamic Republic during this period.
Trade between Turkey and Iran has risen sharply over the past decade.
Turkey was Iran's fifth-largest oil customer in 2011, buying around 200,000 barrels per day, 30 percent of its total imports and more than 7 percent of Iran's oil exports.
The two countries' officials plan to mutual trade to $30bln by 2015.
The remarks were made by Chairman of the parliament's National Security and Foreign Policy Commission Alaeddin Boroujerdi in a meeting with Leader of the Islamic Unity Party of the People of Afghanistan Mohammad Mohaqiq in Tehran.
Referring to the historical, cultural and religious affinities between the two nations, Boroujerdi said the Islamic Republic of Iran has always backed the Afghan nation in all ups and downs in the past three decades and hosted millions of Afghan refuges.
Given the invaluable experience of Iranian parliament over half a century, he said there exists good ground for expansion of broad-based parliamentary relations and economic cooperation between the two countries.
Mohaqiq, for his part, referred to the longstanding cultural and religious ties between the two countries, and called for benefiting from each others' capabilities to broaden economic cooperation.
Iran is one of the most important donors to Afghanistan which has kept its promises to help with the reconstruction of the war-hit country.
Iran has built some roads, power transmission lines, and border stations, among the other infrastructure projects which would better link the two nations.
Iran has also contributed more than $50 million annually to Afghan anti-narcotics efforts in the last 8 years.

After the vote, U.S. ambassador to the UN, Susan Rice criticized the vote from her seat in the assembly, saying, "Today's grand pronouncement will soon fade and that the Palestinian people will wake up tomorrow and find little has changed except the chance for a durable peace has receded."
Rice went on to ridicule the Palestinian action as "unilateral," a strange use of the term, considering that the Palestinians took their case to an international governing body, and their bid for statehood received 138 out of a possible 188 votes.
Comment: In speeches after the vote win, UK ambassador acknowledged that it abstained because Abbas refused to give up the right to prosecute Israel for war crimes
The American entertainer's representatives are set to issue a statement, the news wire said late Wednesday, in which they will claim Wonder believes taking sides in the Israeli-Palestinian conflict clashes with his role as a "Messenger of Peace" for the United Nations. He has held that honorific title since 2009.
JTA based its reporting on "a source who has read email exchanges between Wonder's representatives and organizers of the event."
The Los Angeles event raises millions of dollars every year to support Israel's military. Wonder performed at a gala marking Israel's 50th anniversary in 1998.
Three years earlier, however, he was photographed in Jerusalem receiving a traditional Palestinian kafia headdress from an aide to Yasser Arafat, then the chairman of the Palestine Liberation Organization. Wonder was in Israel to perform a concert. AFP, the French Press Agency, reported that he said he was happy "to see the Holy Land in spirit."
An online petition at change.org had reached 4,000 signatures by Wednesday evening after going online Tuesday. It called on Wonder to "remember that apartheid is apartheid, whether it comes from White Afrikaaner settlers of South Africa or from Jewish Israelis in Israel."
Comment: Gilad Atzmon writes:
According to reporting from the Daily Caller, fearing he will look as though he's taking sides in the Israeli-Palestinian conflict, singing/songwriting legend Stevie Wonder, has withdrawn from his starring role in a Dec. 6 Los Angeles benefit for the murderous IDF.
The truth, really, then, is that Wonder is taking sides. He is clearly against Israeli militarism. He sides with Justice i.e. Palestine
If the report proves accurate, it may as well mean that Jewish Power is falling apart.
It is about time...
Comment: One more sign of the utter inanity that is modern Western civilization under the American Empire. Yes indeed, the 'end' must really be near when so many people are fascinated by such moronic tripe.
